摘要
采用DSP+FPGA的线性流水阵列结构的数字图像处理器完成目标数据采集和处理,研制了基于DSP的电视测量跟踪器。针对欲测量地标的背景复杂的情况,在图像处理算法上采用基于遗传算法的图像模板匹配算法,有效降低了计算量,提高了匹配精度,取得了较好的实验效果。该算法还具有每帧图像匹配计算时间基本恒定的优点,便于在实际系统中采用。
The TV measuring and tracking system base on DSP is developed.It is high-speed,intelligent and programmable system.The system uses height-performance DSP to realize the real-time digital image processing algorithm,at the same time it uses large-scaled programmable logical array CPLD to control logic and field programmable gate array FPGA to preprocess the image.Aim at the condition of measuring landmark in complex background,a method of fast image template matching algorithm based on evolutionary algorithm is proposed.Matched computing time being constant,the method can achieve high computing efficiency and good matching results.
