Abstract
A real-time multi-channel high-definition image mosaic system is designed based on FPGA. First, the best matching pointsare obtained by the improved SIFT feature point matching algorithm. Wide Angle camera's internal and external parameters are calculated using the image calibration method. According to sphere reverse projection principle and the camera’s parameters, transform matrix are generated. Then, FPGA can completetransformation,projection,mosaic and display for each high-definition image in parallel.In this paper, thetransform matrix is calculated by image calibration algorithm.Multi-channel high-definition video mosaic system based on FPGA is realized. The design has very strong practicability.
