3D Stereo Rendering Using FPGA

Stereo rendering presents a virtual 3D scene from two slightly different vantage points. It is of great importance in the field of machine vision, robotics and image analysis. This paper proposes a stereo vision system that is realized in a single field programmable gate array (FPGA). Calculations of the stereo pairs are made by using two-center projection (off-axis) method. The first red resultant image is for left eye while the second blue one is for right eye; the 3D illusion is produced when looking to them using anaglyph. This computer graphic hardware system is implemented using Spartan3E XC3S500E FPGA kit. The execution time for the proposal is 1266 faster than OpenGL time with maximum operating frequency of 35.417 MHz, while the max occupation area reaches 84%.
