Computational Photographic System for Depth Resolution Imaging
This invention is a method for acquiring 3D imagery using an adaptation to existing SLR camera systems that allows for full 3D imagery to be obtained without sacrificing the inherent imaging capability of the camera. This adaptation allows for relatively low cost implementation of 3D technology into already existing camera systems. Through the use of...
