Abstract

The present invention is a device for displaying ultrasound, X-rays, MRI tomography images in three dimensions. The white strip is rotated to form a cylindrical screen, and the 3D image is projected onto the cylindrical screen, which becomes smaller in diameter from the outside. 36 cylinder screens are formed by varying the rotating diameter using a 36-piece strip screen. If the image corresponding to the depth of 10 degrees is reflected by depth, the three-dimensional image which can see the outside and the inside simultaneously is formed. It is attached to the outermost band screen, the innermost band screen, or attached to the same disk, and rotates one time at the same time, and can display three-dimensional still images with 1,296 images. Rotating the strip screen at high speed can also display 3D video. The human brain has the ability to fill the image of the expected point, so if you display the 3D image with 24 to 36 depths, it will be recognized as a 3D image without difficulty.

Several three-dimensional image display devices have been developed so far. Some projectors display images by rotating the screen while rotating the screen at high speed, while others display images corresponding to 15 degrees around the rotation of the screen. In the former case, the screen is rotated at a very high speed. In the latter case, the quality of the 3D image is inferior to that of the former.

The present invention forms a cylindrical screen by using a translucent white band screen through which light is transmitted through the mirror instead of the cylinder by using a principle in which an image is formed in the air when a cylinder with a mirror plated outside is rapidly moved in the air in front of the projector. It is a device to project the image. You can see the image in front of the screen, but you can see the image from behind the screen, so you can see the 3D image from anywhere in 360 degrees.

Existing 3D image display devices are limited to make the screen rotate at high speed due to the difficulty of rotating the screen at high speed, and the device rotating at low speed is deteriorated in image quality. The present invention is a device for displaying ultrasound, X-rays, MRI tomography images in three dimensions. The translucent white stripe screen is rotated to form a cylindrical screen, and the three-dimensional image is projected on a cylindrical screen that becomes smaller in diameter from the outside. 36 cylinder screens are formed by varying the rotating diameter using a 36-piece strip screen. When the image corresponding to each of the 10 degrees is reflected on it, a three-dimensional image is formed that can simultaneously see the outside and the inside. It is attached to the outermost band screen, the innermost band screen, or attached to the same disk, and rotates one time at the same time, and can display three-dimensional still images with 1,296 images. Rotating the strip screen at high speed can also display 3D video.

While rotating the translucent white band screen 1, 36 projectors 8 project a 10 degree image in front of themselves on the screen it creates in the air. White band screens with different rotation radii create a cylindrical screen (2) with different radii, so the projector controls the computer to project images of 36 different depths in keeping with the progress of the screen. The 36 projectors project each of the 36 depth images corresponding to their position alternately with the strip screen in the prescribed order.

Adjust the focal length of the projector 8 and the angle of the mirror 3 (3) to illuminate the image from the outermost band screen to the innermost band screen.

It is also possible to connect the rod (5) fixing the band screen to the rotating shaft (6) by connecting to the arm made of black carbon fiber or titanium instead of the transparent disc (4). The black arm passes at high speed so it does not block the view. In either case, to counteract the difference in centrifugal force caused by the different diameters, the metal wire is placed in the fixed bar (5) inside as a counter weight.

The present invention can be rotated at a slower speed than the existing device, and the cylindrical screen has a depth in reality, so that the outer and inner parts of the human organs can be displayed more three-dimensionally. Ideal for shooting display device. Since the human brain has the ability to fill the image of the expected point, it can be recognized as a 3D image by displaying a 3D image with 24 to 36 depths. Because it is a translucent screen, images can be viewed from the front and back of the screen, and because of the band screen, high-quality three-dimensional images can be produced even at low rotation speed without blocking the images made by other band screens. When displaying a three-dimensional image that does not need to display the inside, such as a beverage can, it is possible to rotate a opaque white pipe or a high-gloss metal pipe to make a clear three-dimensional image.
