Abstract :
Correcting infrared camera distortion is necessary in target tracking and object recognition system. The existent FPGA algorithm didn´t utilize sufficiently the advantage of the parallel processing and leaded to the results that a great deal of the system resources were consumed and the running speed was slowed down. The paper analyzed the existing problems such as serial structure in other algorithms, proposed a new parallel algorithm and realized it with the lowest resources. The experiments carried on the chip-virtex5 produced by Xilinx company show that the proposed algorithm has a good real-time performance, use less resource than previous structure and realize the correction of distortion on FPGA on line.
