Depth-map based on single-passive sensor

In this paper, we propose a novel means of single passive sensor based on depth map generation using PSF (Point Spread Function) model. PSF model was created based on disk-type in pre-processing step, and in the post-processing stage, reference images are generated through convolution operation. In considering the amount of operation and performance, we compared various equations of correlation. It also applied a histogram stretching for robust to different color of lighting. Also, it is designed in the hardware structure, and was verified processing in real-time (30 fps or more).
