Abstract

In order to improve the tracking accuracy and enhance the adaptation ability in the complex environment of image processing system, a multi sensor fusion image tracking system based on CPCI architecture is designed. Aiming at high resolution and high frame rate image acquisition, target searching and tracking, the embedded image processing platform based on FPGA+DSP is designed and implemented. Using CPCI standard bus as data sharing channel, the real-time computation is done by the embedded image processing platform, data center completes data fusion of tracking results and system integrated control. Experimental results indicate that the system can realize multi-channel high resolution Camera Link or HD-SDI image fusion tracking processing, it has good real-time performance, high tracking precision and strong ability of expansion, and provides a reliable solution for image fusion tracking system.
