Definitions

  • the invention consists of a scanning device and a procedure enabling a three-dimensional body surface scan, especially suitable for scanning feet in order to produce fitting shoe lasts and consequently comfortable shoes. This method is particularly suitable for making ski boots, which need to fit their individual owners' feet.
  • the invention falls into the class G 01 B 11/24 of the International Patent Classification.
  • the document EP 0 422 946 patents a device for measuring bodies with irregular shapes, such as shoe lasts.
  • the device scans the shoe last surface point by point by rotating around the last and simultaneously moving along its main axis.
  • the measuring module of the device is put together of two CCD line cameras symmetrically arranged according to the point laser projector.
  • the document reveals that the device is primarily designed to scan shoe lasts, each one separately. The scanning procedure is time consuming an as such inappropriate for scanning live and moving parts like feet.
  • the device is able to measure only one foot at the time.
  • the foot needs to be inserted into the opening of the platform.
  • the measuring module mounted under the platform scans the foot by rotating for 360°.
  • the measuring module works according to laser triangulation, where lines scan the surface of the foot. It comprises a video camera and a laser projecting a laser plane. It takes only a moment to make a cross section of the foot.
  • the entire foot surface is reconstructed based on the scanned profiles.
  • the device from the patent document US 2004/0184040 functions according to the photogrammetry principle.
  • the person being scanned steps on the platform, which has photogrammetic landmarks that help the measuring module (consisting from a camera and lights) to orientate in the room in order for the camera to record these landmarks and the foot.
  • a special elastic layer with photogrammetic landmarks drawn on it should beforehand cover the foot or any measured object.
  • the measuring module then rotates around the foot making a full circle (360°).
  • the weak point of this innovation is that prior to the measurement the subject needs to put on special socks - that is time consuming, non-economic, imprecise (due to enlarging the foot) and unhygienic.
  • Another flaw lies in the measuring principle itself and the related recognition of the photogrammetic patterns. It is well known that this technique demands a lot of processor capacity and that it is sensitive about possible disturbances such as foot movement or inadequate lighting in the measurement room.
  • the 3D body surface scanner also very suitable for scanning feet takes advantage of the feet scanning principle based on the rotation movement and on the rotation of the triangular module comprising two cameras and a laser projector, a main and step-on platform, and a mechanism enabling circulation and rotation of the measuring module.

  • the 3D body surface scanner which is also very appropriate for scanning feet, functions according to the principle of circulation and rotation of the laser triangular measuring module.
  • the construction of the scanner is shown on Figures 1 and 2, the block scheme of the device and of the measuring module are shown on Figures 7a and 7b.
  • Figures 3a, b, c, d will help explain the functioning of the device.
  • the procedure of the body surface scan which is particularly suitable for scanning feet, consists of the following series of movements (when scanning clockwise):
  • the second axis B starts to rotate (Figure 3a). Once the measuring module reaches the angle at which the laser plane intersects with the first rotation axis A, this axis stops. Then, measuring module 1 starts to rotate around the first axis A ( Figure 3b). The rotation around the first axis A stops and the rotation of the measuring module 1 around the second axis B commences ( Figure 3c). The rotation around the second axis B finishes ( Figure 3d). The second axis B is added because of the shadow and the related non-scanning of the inner side of the foot, when the other foot is placed between the measuring module 1 and the surface ( Figure 4). Furthermore, the coverage is improved due to the usage of two cameras 7,8 that are symmetrically mounted according to the laser plane ( Figure 6).
  • Measuring module 1 which is based on the principle of laser triangulation by lighting the surface with lines, consists of a laser line projector 9 and at least one camera 7.
  • the laser line projector 9 illuminates the scanned body with a light plane.
  • the intersection of the plane and the surface of the scanned body is called an intersection curve.
  • a camera captures the illuminated surface from another optical angle.
  • the light is dispersed at the intersection curves and a portion of it is mapped onto the sensor surface of the camera through the lens of camera 7.
  • the shift of the scanned surface causes a relative change of the position of the intersection curve image on the camera.
  • the image enables us to determine coordinates of the intersection curve, which shall be the basis for calculating 3D point coordinates on the surface of the measured body by means of data about camera 7, the laser line projector 9 and their mutual position.
  • Figure 5 depicts the functioning principle of the laser measuring module with one camera 7.
  • Figure 7a shows a block scheme of the three-dimensional body surface scanning device. It comprises a measuring module 1 , a rotating mechanism 2,2' for moving measuring module 1 , a power unit 3, a computer 4, a monitor 5 and a keyboard 6.
  • Measuring module 1 consists of two cameras 7 and 8 and a laser line projector 9.
  • the computer 4 has a two-way connection to the measuring module 1 and through the RS232 interface 10 the rotation mechanism 2,2' for moving the measuring module 1 is connected.
  • monitor 5 and keyboard 6 are connected to the computer 4.
  • the device makes a three-dimensional foot scan.
  • the operator or the scanned person respectively launches the scan by means of the keyboard 6 or in another computer recognizable way (by voice command, by a specific key, touch screen etc.)
  • the computer 4 sends a signal through the RS232 interface 10 to the control electronics of the rotation mechanism 2,2' to start movements as they are depicted in Figures 3a, b, c, d.
  • the control electronics of the rotation mechanism 2,2' sends signals through the interface RS232 to the computer about when certain movement phases actually begin and finish.
  • the computer 4 only captures the image from the cameras when the measuring module moves (rotates) evenly, that is in periods that are marked by the previously mentioned signals of the control electronics. After all three movements are finished, the captured data is processed.
  • the result is in phase one a cloud of three-dimensional points that mark the surface of both feet.
  • the computer analyses these points and specifies significant dimensions, such as length, height, width and breadth on every cross section of both feet.
  • the results of this analysis are then graphically displayed on monitor 5, printed out and saved into a database.
  • the measuring procedure is now complete. If this scan should take place in a store, the computer algorithm may continue and chose a shoe that fits the customer's foot best.
  • Both feet are measured simultaneously. The person scanned does not need to hop from one foot to the other and the most important thing; both feet are in a correct and relaxed position. Furthermore, the measuring time is extremely short,
