摘　　要：采用图像处理技术与视频监控技术,能够有效解决人工监测所带来的不足。应用图像处理中的背景差分法、滤波处理和阈值求取与判断等,对视频监控中的排水口排放情况进行判断。结果表明,背景差分能够有效对图像进行识别出所污染的范围,并通过使用Otsu获取阈值并进行判断是否为污水,从而有效识别判断出排放污水的情况,能够及时做出预警功能并处理。Image processing technology and video surveillance technology can effectively solve the insufficiency caused by manual monitoring. Uses the background difference method, the filtering process and the threshold seeking and judgment of the image processing, and judges the dis- charge of the drain in the video monitoring. The results show that the background difference can effectively identify the range of pollution, and by using Otsu to obtain the threshold which can judge whether it is sewage, so as to effectively identify and judge the discMrge of sew- age which can timely make early warning and deal with it.
