A real-time video monitoring algorithm for identifying sewage poured into a river channel

Abstract

The invention relates to a real-time video monitoring algorithm for identifying sewage poured into a riverway, and aims to capture the flying process of liquid (target objects) in the splashing behavior into the riverway and judge the behavior of pouring the liquid into the riverway in combination with a riverway region (target region). Liquid is not a rigid body, Therefore, the relation between the front frame and the rear frame cannot be established by using the shape, the size, the color and the like, so that a specific object is not tracked, all regions are scanned and judged, and the problem of recognition difficulty caused by the difference between a water body and a rigid object in an aerial flight falling process is solved by using the local overall consistency in space and time. The method is small in calculated amount and controllable in complexity, and real-time identification is easily achieved.

Description

technical field [0001] The invention relates to the fields of water conservancy, environmental protection and video image processing, in particular to a real-time video monitoring algorithm for identifying sewage dumped into a river. Background technique [0002] As the cradle of life, rivers are closely related to human life. People not only obtain resources such as water and food necessary for life, but also discharge domestic sewage into rivers. The sewers in the city will collect sewage for treatment before discharge, so the impact on the downstream is controllable, but if residents dump domestic sewage directly into the river without treatment, it is easy to cause damage to the water environment and water ecology. If it is industrial sewage other than domestic sewage, it will even threaten the water safety of residents. Today, with surveillance cameras everywhere, using video images to identify sewage dumps can use existing hardware equipment, and with the help of imag...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to propose a real-time video monitoring algorithm for identifying sewage dumped into the river, which can scan and judge all areas, and use the local overall consistency in space and time to solve the problem of water bodies and rigid objects. The problem of identification difficulties brought about by the difference in the process of flying and falling in the air, and the invention has a small amount of calculation and controllable complexity, and can easily achieve real-time identification
