Design of High-Speed Image Processing System for Weak-Dim Target Based on FPGA

A high-speed image processing system for weak-dim target is proposed which is implemented with FPGA. In order to achieve the parallel of image acquisition and processing, the capabilities of the CMV4000, such as exposing the next frame during the read-out of the previous one, windowing and 16 data- output channels, are sued. Besides this, the ping-pang memory structure is adopted. This design achieves long exposure time and high image frequency in a imaging system based on large-scale plane array detector. Experimental results show that the exposure time of image sensor is about 20ms and the image frequency is 50Hz. The system can meet high speed detection and tracking requirements for weak-dim targets. Currently, the system has been applied to the actual project.
