Abstract:
To solve the problem of the small target detection and recognition in outer space, a target detection and recognition system based on dual-DSP and FPGA was designed. FPGA was used for image preprocessing module and serial communication circuit. Compared with some recent patents on target detection and recognition problems, the patents did not design algorithm based on the hardware, as the efficiency was very low. Fixed-point DSP was used to realize a visible light target detection and recognition algorithm. Floating-point DSP was used as communication and control algorithm. Practical application approved that the system perfectly met the requirements of the target detection and recognition in deep space.
Keywords:
