The method of edge detection binocular stereo-vision system based on FPGA must have characters of strong noise-rejection,high position accuracy,good real-time performance and hardware implementation easily.This paper proposes a modified SUSAN algorithm for edge-detection which is well suited to the FPGA-based binocular stereo-vision system.Firstly,the original response and normal direction of each pixel is calculated by SUSAN algorithm.Then non-maximum suppression is applied according to the distance threshold between USAN barycenter and center.Finally,connecting the edges and getting the edge images.The algorithm is programmed by Verilog HDL and implemented in FPGA.The result indicated that the design performance is good when applied to stereo matching.
