| Abstract: | Because of large amounts of image data and difficultly implementing real time image processing, a hardware system based on high performance TMS320C6201 DSP is presented. It can fulfill real time compressing correction of IR image nonuniformity. According to two points correction formula, the hardware correction principle and the specific steps are described in the paper. Experimental results prove that Its imaging quality is satisfying, the correction method is simple and the program debug is convenience. This way can effectively solve real time problem in infrared image processing. |
