Paper Abstract

A three-dimensional (3D) imaging system using multi-cameras is presented. Perspectives of a 3D object are taken by the multi-cameras located randomly on a circle. The 3D object can be reconstructed numerically by waveform reconstruction with an angle correction function. The angle correction function is introduced to correct the angle of camera at each pixel in the projected image and at each 3D reconstructed position. Numerical results show that point sources can be reconstructed successfully. Experimental results of two 3D objects are also presented.iminates defocused areas. The depth of a three-dimensional object can be accurately detected from a blur measure and the resolution and quality of reconstructed plane images are slightly enhanced by adaptive erosion operation. Therefore, we qualitatively expect this scheme to work well in the specific task such as a part of the system for object detection and recognition in integral imaging.
