视频监控中的运动目标检测 摘要 本项目通过visual C++和open CV函数库的连接来实现视频监控中的动目标检测。Open CV是一种用于数字图像处理和计算机视觉的函数库，其提供了针对多种形式的图像和视频源文件（实时摄像头）的帧提取函数和许多标准的图像处理算法。 本项目主要围绕视频采集、运动目标检测两个方面进行编程，视频采集方面采用cv create video writer 函数来存储视频流文件，运动目标检测方面采用静态背景下常用的运动目标检测算法背景差分法，该方法可以稳定的提取背景图像，抑制运动目标背景的干扰，有效的提高运动目标的检测概率。同时，还采用另外一种方法——帧间差分法进行运动目标的检测，并比较两种方法的不同点。 关键词： 视频 背景差分 目标检测 open CV 帧间差分法 Abstract In this item, we achieve the goal of moving object detection in military video monitoring through the connection of VC++ development software and Open CV. Open CV is a library for digital image and computer, which provides various functions to extract frame from image sequence and video source (real-time camera. et) and many of the standard image processing algorithms. This item is focus on video capture, motion detection and tracking two aspects. In video capture, we store the video stream files by using the cvCreat Video Writer, In motion target detection, the most frequency used method, moving objects detection algorithms is used ,which is based on stationary scene,. The result shows that the algorithm can extract the background image steadily, and inhit inference from background to moving objects, thus increased the probability of detection of moving object effectively. Also, we used another method, coterminous frame difference to detect the moving object. And found out the difference between them.
