Summary:提出了一种快速检测方法.以动态传送带与物料袋为研究对象,用改进的五帧差分法提取运动物料袋图像,同时以中间帧图像为参照进行单高斯背景更新；采用中间帧图像与背景图像做差,将得到的前景图像与帧差法得到的运动图像进行形态学“与”运算；当帧数满足给定条件时,表明该帧为完整物料袋图像,保存帧图像,并对不满足该条件的相邻帧图像通过加运算补偿.实验结果表明,该方法可以得到准确、快速的检测结果,并且对环境变化具有较强的鲁棒性.

The article proposes a rapid detection method.Firstly,the article takes the dynamic conveyor belt and the plastic bags as the research object,uses the improved five-difference method to extract the images of moving material bags,At the same time,it takes the intermediate frame picture as a reference to update background ;Then using the difference between the middle frame image and the background image,and makes morphological and operation between the foreground image and the moving image obtained by frame difference method;When the number of frames meets special condition,it shows that the frame includes complete image information of material bag,and saves the frame image,continues to detect;Oppositly,then compensate the adjacent frames which is not satisfied the condition by add operation.the experimental results shows that the method is accurate and fast,and has a
