Abstract: The detection and parameters estimation of strange motion target are the keys of intelligent surveillance.A new method of motion target parameters estimation based on monocular sequence images is presented,in order to avoid the defects of complicated traditional computer binocular vision system.The relation between the distance of the camera and motion target,and the counterpart on images is derived,based on imaging geometrical principle.The position and velocity are estimated with the parameters of the camera.The experiment results show the method is simply and feasible.

Key words: sequence image, motion target, imaging geometrical principle, image processing

摘要: 可疑运动目标的检测和参数估算是智能视频监控的关键。为克服传统计算机双目技术系统复杂等缺点,提出一种单目运动目标识别技术并估算目标运动参数的方法。利用几何成像原理,推导出运动目标与固定摄像机的实际水平距离和目标在二维图像中的位置之间数学模型,结合摄像机参数,估算出目标实际位置及运动速度。通过搭建的硬件平台和编写的测试软件,在实际码头对海面目标的参数估计进行了实验,结果显示了该方法简单、有效和可行。
