Study on High-speed Synthesis Method of Polarization Images in the Small Moving Target Detection System
System resources used are limited, and large image data continuously produce in a small moving target detection system based on polarization imaging technology. To ensure good real-time, the three-source images pixel-level synthesis method was studied in two stages, including data transmission and pixel synthetic. FPGA designed the multi-input and single output logic. Three-source images are merged into the single-way data stream. This stream uses a special format supporting TS201(the DSP chip) to simultaneously process four consecutive pixels. Ping-pong type buffer based on DMA advanced parallelism of data transmission and data processing. On the basis of TS201 CPU features and optimized mathematical model, a kind of pixels synthesis computing method based on four pixels parallel operation and pipelining was put forward. In 12bit pixel precision and 782×582 pixel area conditions, hundreds of tests were carried out, and proved that the average time of polarization image synthesis is 26.02 ms without data loss.
