The invention discloses a platform for verifying infrared video image processing algorithm realization accuracy. The original video image of an infrared detector and the image processed by the hardware can be transmitted to a video receiving and comparing module, the video receiving and comparing module is used for carrying out software simulation processing on the original video image, and then the image subjected to hardware processing and the image subjected to software simulation are compared frame by frame and pixel by pixel, and whether the two images are consistent or not is determined,so that the accuracy of the hardware processing algorithm can be determined. According to the invention, the synchronous output of the original infrared video stream and the infrared video stream after the hardware processing is realized, the video stream is transmitted to the video receiving and comparing module through the Gigabit Ethernet, and the video receiving and comparing module uses a digitalized means, the video image subjected to software simulation and the video image processed by the infrared detector are compared, the difference of the software and hardware processing results isfound, and compared with a traditional manual comparison mode, the platform is more efficient and accurate.
