This imaging guiding arithmetic evaluating system is used to evaluate the precision and stability of a guiding arithmetic on complex backgrounds, analyze the effects of sampling frequency, field of vision, template size,etc. It has the character of simply structure, lower cost and small volume. This system can either be used in outfield testing or be used in infield experiment by using formerly accumulated data. Guiding arithmetic program compiled by user can be joined into this system, and then the performance of this guiding arithmetic can be tested easily. The hardware structure and software flow is briefly expounded in this paper.
