Abstract

A novel 360-degree 3D image acquisition system that captures multi-view images with narrow view interval is proposed. The system consists of a scanning optics system and a high-speed camera. The scanning optics system is composed of a double-parabolic mirror shell and a rotating flat mirror tilted at 45 degrees to the horizontal plane. The mirror shell produces a real image of an object that is placed at the bottom of the shell. The mirror shell is modified from usual system which is used as 3D illusion toy so that the real image can be captured from right horizontal viewing direction. The rotating mirror in the real image reflects the image to the camera-axis direction. The reflected image observed from the camera varies according to the angle of the rotating mirror. This means that the camera can capture the object from various viewing directions that are determined by the angle of the rotating mirror. To acquire the time-varying reflected images, we use a high-speed camera that is synchronized with the angle of the rotating mirror. We have used a high-speed camera which resolution is 256×256 and the maximum frame rate is 10000fps at the resolution. Rotating speed of the tilted flat mirror is about 27 rev./sec. The number of views is 360. The focus length of parabolic mirrors is 73mm and diameter is 360mm. Objects which length is less than about 30mm can be acquired. Captured images are compensated rotation and distortion caused by double-parabolic mirror system, and reproduced as 3D moving images by Seelinder display.
