Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only embodiments of the present invention and do not represent all of the technical idea of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be variations and variations.

As described in [Technical Solution], the three-dimensional camera according to the present invention can be effectively used for close-up photography, and has a configuration and effect that can widen the selection range of the lens usable in the first imaging lens assembly. However, below, only the configuration for achieving the object described in [Technical Problem] will be described.

In the present specification, the '~~ imaging lens assembly' may be made of one lens but may be made of two or more lenses.

1. Configuration to easily adjust binocular parallax

Figure 2 is a perspective view showing a horizontal monocular stereoscopic camera according to a first embodiment of the present invention, Figure 2a is a view showing a three-dimensional camera with a portion of the case removed.

Referring to the drawings, the stereoscopic camera 100 includes a case, a first imaging lens assembly 10, and a mirror box 20 including a half mirror H installed at the rear of the first imaging lens assembly 10. And a sliding unit 24 for moving the mirror box 20 in the front-rear direction (± x direction), the first mirror unit 30 for reflecting backward the light reflected by the half mirror H, A second mirror unit reflecting the light passing through the second imaging lens assembly 51, the right eye camera 60, and the half mirror H to the rear, installed on the optical path reflected by the first mirror unit 30 ( 40, the second imaging lens assembly 52, the left eye camera 70, and the first and second mirror units 30 and 40 installed on the optical path reflected by the second mirror unit 40. Rotation means for making. The components of the stereoscopic camera 100 have the arrangement as shown in FIG. 1.

The first imaging lens assembly 10 is installed on the front panel 2 of the case. The first imaging lens assembly 10 converges the light incident from the subject 1. The first imaging lens assembly 10 is preferably installed to be interchangeable. A suitable lens may be selected and installed in consideration of the photographing purpose, the type of the subject 1, the distance to the subject 1, and the like.

Light rays passing through the first imaging lens assembly 10 are incident on the mirror box 20. As shown in FIG. 3, the mirror box 20 includes a fixing frame 21, a half mirror H installed perpendicular to the fixing frame 21, and a mirror M installed to be perpendicular to the half mirror H. do.

As for the fixing frame 21, the part in which the half mirror H and the mirror M are provided, and the part which becomes the path | route of the light beam reflected by the mirror M are opened. Therefore, the light rays reflected by the half mirror H travel to the first mirror 31 (first optical path), and the light rays passing through the half mirror H are reflected by the mirror M and then the second light beam. Proceed to the mirror 41 (second optical path).

The mirror box 20 may be slid in the front-rear direction (± x direction) by the sliding unit 24, thereby adjusting binocular disparity. That is, when the mirror box 20 is moved in the front and rear directions, the binocular disparity may be adjusted because the optical axis spacing between the left and the right is widened or narrowed by the first and second mirrors 31 and 41.

As described in [Background Art], the conventional stereoscopic camera has moved the left eye camera and / or the right eye camera itself to adjust the binocular disparity, and thus the structure thereof is complicated and binocular disparity adjustment is very difficult. In contrast, the stereoscopic camera 100 according to the present invention can adjust binocular disparity by moving only the mirror box 20 in the front and rear directions while leaving the left and right eye cameras 60 and 70 intact.

As shown in FIGS. 3 to 6, the sliding unit 24 includes an upper block 27, a lower block 25 coupled to the upper block 27 to be slidable with respect to the upper block 27, and a lower block ( The screw gauge 28 for pushing the linear movement 25 and the elastic member 27b provided between the upper block 27 and the lower block 25 is included.

The upper block 27 is coupled to be fixed to the upper panel 3 of the case, and the upper surface of the mirror box 20 is coupled to the lower block 25. The upper and lower blocks 27 and 25 are coupled to each other so as to be linearly slidable by the rail structure 27a.

On the other hand, the sliding unit 24 may be provided below the mirror box 20, not on the mirror box 20. That is, the upper block 27 is coupled to the bottom panel 4 of the case, the lower block 25 is slidable above the upper block 27, and on the lower block 25 of the mirror box 20. The bottom face may be combined.

The presser plate 26a is provided in the side surface of the lower block 25, and the long hole 26b of an x direction is formed in the presser plate 26a. In addition, a bolt hole 25b is formed at the side surface, and the knob 26 is screwed to the bolt hole 25b. When the knob 26 is rotated forward and the pressure plate 26a is pressed, the upper and lower blocks 27 are formed. ) 25 are fixed to each other and the knob 26 is reversed to release the pressurization and the lower block 25 is allowed to slide. Therefore, when binocular parallax adjustment is required, the upper and lower blocks 27 and 25 are fixed by sliding the lower block 25 and rotating the knob 26. Meanwhile, even when the sliding unit 24 is coupled to the bottom panel 4, the upper and lower blocks 27 and 25 are fixed in the same principle.

 The screw gauge 28 is installed in the upper block 27. The screw gauge 28 includes a thimble and a spindle that is moved in a straight line by the rotation of the thimble. The screw gauge 28 is used for micrometers and the like because the spindle can be moved very precisely, and its structure is already known. Therefore, detailed description of the screw gauge 28 will be omitted.

As shown in FIG. 6, the elastic member 27b is installed to connect the upper and lower blocks 27 and 25 between the upper and lower blocks 27 and 25, and the upper and lower blocks 27 ( 25) apply an elastic force that pulls in the direction of each other. Therefore, the tip of the screw gauge 28 is always kept in close contact with the protruding portion 25a by the elastic member 27b, whereby the screw gauge 28 can move the lower block 25 precisely. have.

2. Configuration for rotating the first and second mirrors (configuration for main time adjustment)

The light beam reflected by the half mirror H travels to the first mirror 31 and is then reflected by the first mirror 31 to sequentially pass through the second and third imaging lens assemblies 51 and 61 to capture an image. Rays reaching 63 (first optical path) and passing through the half mirror H are reflected by the mirror M and proceed to the second mirror 41 and then reflected by the second mirror 41. And sequentially pass through the second and third imaging lens assemblies 52 and 71 to reach the imaging surface 73 (second optical path).

In the present invention, in order to adjust the viewing angle, the first and second mirror units 30 and 40 are rotated instead of rotating (or rotating) the left and right cameras themselves. Therefore, the configuration for adjusting the viewing angle is simpler and more efficient than the conventional stereoscopic camera.

As shown in FIG. 7 and FIG. 8, the first and second mirror units 30 and 40 may include a support 32 installed on the bottom panel 4 of the case so as to be rotatable, and a fixing part installed on the support 32. And a first mirror 31 or a second mirror 41 provided in the fixing portion, and a protrusion 39 formed to protrude laterally to the support 32.

The fixing part is supported by the support panel 33 vertically installed on the support base 32, the pedestals 35 and 36 and the pedestals 35 and 36 respectively provided on the upper and lower ends of the support panel 33. The first mirror 31 or the second mirror 41 provided on the 33, the bolts 37 for coupling the pedestals 35 and 36 to the support panel 33, and the image of the support panel 33. It includes an elastic means 38 are respectively installed at the bottom.

Protruding portion 39 is a portion protruding to have a cross-sectional shape '' 'on the side of the support (32). Rotating rod 81 is inserted into the protrusion 39 so as to be rotatable. The protrusion 39 is always in close contact with the stepped jaw 82 by the pushing force of the elastic spring 83.

The first and second mirror units 30 and 40 may be rotated (or rotated) by the rotating means. The rotating means includes a rotating rod 81, an elastic spring 83 provided at both ends of the rotating rod 81, and a nut member 85 provided at the bottom panel 4.

The rotating rod 81 extends from the first mirror unit 30 to the second mirror unit 40. Accordingly, one end of the rotating rod 81 corresponds to the first mirror unit 30, and the other end of the rotating rod 81 corresponds to the second mirror unit 40.

Both ends of the rotating rod 81 are rotatably supported by the bearing 84, and the center portion of the rotating rod 81 is inserted into the nut member 85. A thread (not shown) is formed on at least a portion of the rotating rod 81, preferably the outer circumferential surface of the center portion, and a screw thread is formed on the inner circumferential surface of the nut member 85 for screwing with the screw. Therefore, when the rotating rod 81 is rotated in the forward or reverse direction by the user, the rotating rod 81 is moved to the left or the right.

Both ends of the rotating rod 81 are provided with a stepped jaw 82 and an elastic spring 83. The staircase 82 is formed at a position corresponding to the protrusion 39, and the elastic spring 83 applies a pushing force so that the protrusion 39 is always in close contact with the staircase 82. Due to this structure, the protrusion 39 is always kept in close contact with the staircase 82 between the elastic spring 83 and the staircase 82, so that the rotating rod 81 to the left or right When moved, the protrusion 39 is also moved to the left or the right, and accordingly, the first and second mirror units 30 and 40 are rotated (or rotated) precisely.

At this time, since the first and second mirror units 30 and 40 are located at opposite sides with respect to the rotating rod 81, the first and second mirror units 30 and 40 rotate in opposite directions to each other. )

Specifically, when the rotating rod 81 is rotated and moved to the right side (+ y direction in FIG. 7), the first mirror unit 30 is rotated in the counterclockwise direction (AR1 in FIG. 7) about the z-axis. 2, the mirror unit 40 is rotated in the clockwise direction (AR2 in Fig. 7) around the z-axis so that the viewing angle is close (the convergence point moves in the direction close to).

Then, when the rotating rod 81 is rotated and moved to the left side (in the -y direction of FIG. 7), the first mirror unit 30 rotates clockwise around the z axis and the second mirror unit 40 moves to the z direction. It rotates counterclockwise around the axis, causing the viewing angle to be farther away (the convergence point moves farther away).

As such, by moving one rotating rod 81, two mirror units 30 and 40 can be simultaneously rotated in opposite directions at the same time, thereby allowing easy and quick adjustment of the viewing angle.

Meanwhile, in the above description, a configuration in which one rotating means (one rotating rod) rotates all of the first and second mirror units 30 and 40 is described, but the first and second mirror units 30 and 40 are Each rotating means (rotating rod) may be provided, and each rotating means (rotating rod) may rotate only the mirror unit 30, 40, which is configured as the first and second mirror units 30 and 40. ) Can be separated and rotated (rotated at different angles).

3. Configuration for adjusting the tilt of the first and second mirrors

Conventionally, in order to adjust the height and tilting value of the third imaging lens assembly (61, 71), the height and tilt of the left and right cameras are adjusted. This conventional configuration is very complicated in structure, expensive in equipment, and adjustable. There was a problem with this difficulty. In contrast, in the present invention, the optical axis is adjusted to the height and the tilting value of the third imaging lens assembly 61 or 71 by adjusting the inclination of the first and second mirrors 31 and 41. It has the advantage of being very simple, inexpensive equipment and easy to adjust.

As described above, the fixing portion is a support panel 33 vertically installed on the support base 32, pedestals 35 and 36 respectively provided on the upper and lower ends of the support panel 33, and the pedestals 35 and 36. A first mirror 31 or a second mirror 41 supported on the support panel 33, a bolt 37 for coupling the pedestals 35 and 36 to the support panel 33, and a support panel. An elastic means 38 is provided at the upper and lower ends of the 33, respectively.

As shown in FIGS. 9 to 11, first bolt holes 33a and grooves 33b are formed at upper and lower ends of the support panel 33. The first bolt hole 33a is positioned to correspond to the second bolt hole 35a, and the elastic means 38 is installed in the groove 33b. The elastic means 38 applies a force for pushing the first mirror 31 or the second mirror 41 outward, a sponge or the like can be used.

Pedestals 35 and 36 are detachably installed on the upper and lower ends of the support panel 33 so as to support the first mirror 31 or the second mirror 41. Specifically, a second bolt hole 35a is formed in the pedestals 35 and 36, and the bolt 37 passes through the second bolt hole 35a and is fastened to the first bolt hole 33a. Pedestals 35 and 36 are fastened to the support panel 33.

At this time, a gap exists between the pedestals 35 and 36 and the support panel 33 due to the elastic means 38. When the bolt 37 is adjusted to the depth of the first bolt hole 33a, The inclination of the first and second mirrors 31 and 41 can be adjusted. For example, if the tightening depth of the lower bolt 37 is made shallower than the fastening depth of the upper bolt 37, the first and second mirrors 31 and 41 are inclined backwards, and the lower than the fastening depth of the upper bolt 37. When the fastening depth of the lower bolt 37 is deepened, the first and second mirrors 31 and 41 are inclined forward.

Meanwhile, as shown in FIGS. 7 and 8, bolts 37 are fastened to both sides of the pedestal 36 to the pedestal 36 at the bottom, and the bolts (only at the center of the pedestal 35 are attached to the pedestal 35 at the top). 37 may be fastened. In this case, the lateral inclination of the first and second mirrors 31 and 41 may be adjusted by changing the fastening depths of the two bolts 37 of the lower pedestal 36.

4. Configuration to make the same image size of left and right cameras

In the past, the left eye camera and / or the right eye camera were directly moved to make the same image size of the left and right cameras. However, this configuration has a problem that the structure is very complicated.

In contrast, in the present invention, the image size is the same by linearly moving the second imaging lens assembly 51 while the left and right eye cameras are left as they are.

Specifically, the light reflected by the first mirror 31 sequentially passes through the second imaging lens assembly 51 and the third imaging lens assembly 61 to reach the imaging surface 63 (first light). Path), and the light rays reflected by the second mirror 41 sequentially pass through the second imaging lens assembly 52 and the third imaging lens assembly 71 to reach the imaging surface 73 (second optical path). The left and right cameras are moved by moving the second imaging lens assembly 51 forward and backward with respect to the third imaging lens assembly 61 while keeping the gap between the second and third imaging lens assemblies 52 and 71 intact. Make the phase size the same. That is, in the present invention, the second imaging lens assembly 52 and the left eye camera (the third imaging lens assembly and the aperture and the imaging surface, etc.) and the right eye camera (the third imaging lens assembly and the aperture and the imaging surface) are located on the second optical path. The second image forming lens assembly 51 on the first optical path in the front-to-rear direction (± x direction) with the same size as it is.

To this end, the stereoscopic camera 100 according to the present invention, as shown in Figure 12, includes a support member 55 and the lens fixing member 57.

The support member 55 is installed perpendicular to the bottom panel 4 on the first optical path. The support member 55 has a circular through hole, and a thread is formed on the inner circumferential surface of the through hole. The support member 55 is installed at a predetermined distance from the front end of the right eye camera 60 so that the lens fixing member 57 can have a clearance to be moved in the front and rear directions (± x direction).

The lens fixing member 57 is a ring-shaped member for fixing the second imaging lens assembly 51 therein, and a thread 57a for mating with the screw thread is formed on the outer circumferential surface thereof. A lens fixing member 57 is installed in the through hole so that the threads are screwed, and the second imaging lens assembly 51 is moved forward and backward (± x direction) by rotating the lens fixing member 57 in the forward or reverse direction. The distance between the second and third imaging lens assemblies 51 and 61 may be adjusted.

On the other hand, in the above description that the support member 55 and the lens fixing member 57 is installed only on the first optical path, but the support member 55 and the lens fixing member 57 are installed only on the second optical path or Both may be installed in the optical path, which will be readily apparent to those skilled in the art with reference to the present specification.

For reference, the second imaging lens assembly 51 and 52 may be combined with the third imaging lens assembly 61 and 71 to close the focal position and to reduce chromatic aberration and image curvature.

The third imaging lens assembly 61 forms light reflected by the half mirror H, and the third imaging lens assembly 71 forms light passing through the half mirror H.

The third imaging lens assembly 61 and 71 may be a base lens, and a macro lens capable of close-up magnification may be used. When the magnification is sufficient by using a macro lens for the third imaging lens assemblies 61 and 71, the second imaging lens assemblies 51 and 52 may be removed.

When a telephoto lens is used for the third imaging lens assembly 61 and 71, the third imaging lens assembly 61 and 71 may be combined with the second imaging lens assembly 51 and 52 to be used with the macro lens. It will play the same role.

In order to allow various lenses to be used as the first imaging lens assembly 10, a virtual image formed at the rear of the first imaging lens assembly 10 may be used as the second imaging lens assembly 51, 52 and the third imaging lens assembly. The method of enlarging and photographing using (61) (71) is preferable.

5. Configuration for adjusting the rolling of the right eye camera

The stereoscopic camera 100 according to the present invention matches the left and right eye images by adjusting the rolling of the right eye camera 60. Specifically, as shown in FIGS. 12 to 13, the right eye camera 60 is installed on the goni stage 90, and the goni stage 90 and the right eye camera 60 are connected to each other by a fastening ring 91. Are combined.

The structure of the Gonio stage 90 is disclosed in Korean Patent No. 1234346. By turning the handle 94, the moving stage 93 is rotated about the x axis while sliding about the base stage 92, and thus the right eye camera 60 may also be rotated (rolled) about the x axis. After the right eye camera 60 is rotated by a desired angle, the moving stage 93 is fixed by using the fixing knob 95.

In the drawing, the right eye camera 60 is provided with a rolling adjustment means and the left eye camera 70 is not shown with a rolling adjustment means, but the left and right eye cameras 60, 70 are both provided with a rolling adjustment means or Only the left eye camera 70 may be provided with a rolling adjustment means.

6. Configuration for adjusting the tilting of the left eye camera

The stereoscopic camera 100 according to the present invention has a configuration for adjusting the tilting of the left eye camera 70. Specifically, as shown in FIG. 14, the left eye camera 70 is installed on the goni stage 90, and the goni stage 90 and the left eye camera 70 are coupled to each other by a fastening ring 91. .

The gonio stage 90 is the same as the gonio stage 90 of FIG. 13, but its installation direction is different. That is, in FIG. 14, the gonio stage 90 is disposed so that the moving stage 93 is rotated about the y axis. Therefore, in FIG. 14, when the moving stage 93 is rotated clockwise about the y axis, the second imaging lens assembly 52 is rotated downward, and when the moving stage 93 is rotated counterclockwise about the y axis. The second imaging lens assembly 52 is rotated upward.

In the drawing, only the left eye camera 70 is provided with a tilting control means, and the right eye camera 60 is not shown with a tilting control means, but both left and right eye cameras 70 and 60 are provided with tilting control means. Only the right eye camera 60 may be provided with a tilting adjusting means.
