Video tracking system, which is typical of high tracking precision and stability,strong anti-interference capability, high resolution and low cost，has been widely used inboth military and civilian fields. The applications of video tracking system are varied,and different external influential factors lead to different requirement. With theincreasing resolution and the frame frequency, the data size to be processed increasessharply. The requirement of the extraction and recognition to target in the complexbackground becomes increasingly higher, which increases the complexity of videotracking system and the difficulty of research. This paper proposes and implements adesign scheme based on general video tracking test platform which shortens thedevelopment cycle of the tracking system through the analysis of the overallperformance for the tracking algorithm to multiple tracking scenarios.This paper firstly presents the summary of the video tracking system.
