摘　　要：本文提出一种运动背景下对地多运动目标检测算法。采用最邻近算法和对称约束算法滤除误匹配点对,基于RANSAC算法消除外点的影响,准确估计全局运动参数,提高了运动背景补偿的精度。关联连续运动信息图得到运动历史图,补充空洞。在运动历史图上进行形态学处理,有效地滤除噪声,精确地检测出了多运动目标。实验结果表明本文算法能够精确的进行运动背景补偿,准确的检测出多运动目标。This paper proposes an algorithm for detecting multiple moving targets in the moving backg round.The mismatched pairs are filtered by using the nearest neighbor algorithm and the symmetric constraint algorithm.The outer points based on the RANSAC algorithm are eliminated so that the global motion parameters are accurately estimated.Then the accuracy of the background motion compensation is improved.Correlating the continuous motion information map,so the motion history map is obtained and the void is supplemented.Morphological processing is performed on the motion history map to effectively filter out noise.Eventually multiple moving targets are accurately detected.The experimental results show that the proposed algorithm can accurately compensate the background motion and accurately detect multiple moving targets.
