The design and implementation of plate-profile information collecting and processing system based on FPGA

this paper shows the design and implementation of a video capturing and processing system, which can collect plate-profile information and process image in the spatial domain. Strategy of buffer storage is used in the collecting part; read and write two SRAM at the same time to improve the data throughput. In the processing part using Synchronous FIFO to implement sliding window whose function is to filter image in spatial domain. In the tests, using this system to process plate-profile information gets good result; frame rate can reach 25fps, also meet the need of real-time requirements and have much more obvious advantages than processing image by software programming.
