| Abstract: | A high-speed infrared image data acquisition and recognition system based on TMS320C6416 is designed and implemented. In this system, a real-time image processing unit is made by two DSP chips and a 250 MHz high-speed data acquisition system is made by dual 12 bit 125 MHz AD chips, which can ensure the real-time detection and recognition of weak targets in complex background and also solve the difficulty of clock phase. The real-time characteristics and practical abilities of the system are validated by real-time detection of weak targets in complex background. |
