| Abstract: | An infrared real-time imaging system has been developed. In the system, TMS320C6201 DSP is used as the core unit of image processing,and FPGA as controlling image sampling. In order to improve the real-time performance of the system, utilizing double caching structure is to store middle data, using DMA data joint is to transmit the image data, and programming assembler is to optimize more time-consuming algorithms in image processing. According to infrared imaging system configuration, the system realization principle is explained. At last, the experimental results are given. Experiment proves that the system may be reliable operation and meets the requirement for common algorithm real-time processing for the infrared imaging system. |
