The basic principle, hardware and software structure of the super spectral imaging detecting equipment are introduced. MorphisQXT video grabbing card from Matrox Co. is used to process super spectral imaging data. The system structure and corresponding functions of MIL Lite 8.0 program library are introduced in detail. Under VC++6.0 exploitation environment, fake real time process method of asynchronism double buffer storage is adopted. So image dynamic collection is realized. The images are spliced and added colors. And the function of distinguishing real targets from false targets of super spectral detecting equipment is implemented directly. The experimental results show that MorphisQXT video grabbing card has the ability of collecting large numbers of data in real time.
