【正文】 視頻監(jiān)控中的運動目標(biāo)檢測摘要本項目通過 visual C++和 open CV函數(shù)庫的連接來實現(xiàn)視頻監(jiān)控中的動目標(biāo)檢測。Open CV是一種用于數(shù)字圖像處理和計算機視覺的函數(shù)庫，其提供了針對多種形式的圖像和視頻源文件（實時攝像頭）的幀提取函數(shù)和許多標(biāo)準(zhǔn)的圖像處理算法。本項目主要圍繞視頻采集、運動目標(biāo)檢測兩個方面進(jìn)行編程，視頻采集方面采用 cv create video writer 函數(shù)來存儲視頻流文件，運動目標(biāo)檢測方面采用靜態(tài)背景下常用的運動目標(biāo)檢測算法背景差分法，該方法可以穩(wěn)定的提取背景圖像，抑制運動目標(biāo)背景的干擾，有效的提高運動目標(biāo)的檢測概率。同時，還采用另外一種方法——幀間差分法進(jìn)行運動目標(biāo)的檢測，并比較兩種方法的不同點。關(guān)鍵詞： 視頻 背景差分 目標(biāo)檢測 open CV 幀間差分法AbstractIn 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 puter, which provides various functions to extract frame from image sequence and video source (realtime 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.Key Words: video background difference object detection open CV coterminous frame difference目錄摘要 ..........................................................................................................................................2ABSTRACT.................................................................................................................................3第一章 引言 ............................................................................................................................5第二章 總體方案設(shè)計 .............................................................................................................6 運動目標(biāo)檢測有兩種總體思路 ...........................................................................................6 常規(guī)的運動檢測方法 ...........................................................................................................6第三章 系統(tǒng)調(diào)試 .....................................................................................................................8 幀差法 ..................................................................................................................................8 背景累積差分法 ................................................................................................................10第四章 系統(tǒng)功能與指標(biāo)參數(shù) ................................................................................................12 系統(tǒng)功能 ............................................................................................................................12 關(guān)于閾值的確定 ................................................................................................................12 系統(tǒng)的實際應(yīng)用 ................................................................................................................13第五章 項目總結(jié)
