摘　　要：针对常用光流场计算耗时长以及亮度变化引起约束方程不成立的问题,同时为了获取目标的准确运动信息,在光流计算方程中加入权函数,并引入通用动态图像模型,建立新的光流约束条件;针对光流技术中计算量和信息量间的矛盾问题,采用基于最优估计点匹配技术和光流均匀采样策略的光流场计算方法.实验结果与算法性能评估表明:该方法能实现实时、准确的运动目标检测与跟踪,且具有较好的鲁棒性.In view of the problem that common light flow field calculation takes a long time and brightness changes causes the constraint equation not to hold, and in order to obtain accurate movement information of the target, we used the light flow calculation equation combined with weight function and introduced general dynamic image model to establish the light flow constraint conditions. To solve the problem of contradiction between the amount of calculation and information in the light flow calculation technology, we used optimal estimation of point match technology and uniform light flow sampling strategy of light flow field. Experimental results and performance evaluation showed that this method can achieve accurate real-time detection and tracking of moving objects, and have a better robustness.
