摘　　要：针对传统帧间差分方法对运动物体检测的不可靠性和异常度判定的不准确性,提出一种基于帧差法的改进方法.首先对连续帧图像进行特征匹配并进行坐标位移转换处理,其次对其差分二值图像进行边缘轮廓填充,最后构建一种自适应阈值的指数模型,通过权重衰减,自动降低小物体和远距离物体的权值.通过实验和测试,在监控源位置偏移、小目标和远距离运动目标干扰等情况发生时,其检测的准确性和可靠性得到有效保证.Aiming at the unreliability of traditional frame difference methods in detecting moving objects and the inaccuracy of anomaly detection,an improved method based on frame difference method is proposed.The method first performs feature matching and coordinate displacement transformation on continuous frame images,then fills the edge contours of their differential binary images,and finally constructs an adaptive threshold exponential model.By weight attenuation,the weights of small and distant targets are automatically reduced.Through experiments and testing,the accuracy and reliability of its detection are effectively guaranteed when monitoring source position deviation,small targets,and long-distance moving target interference occur.
