Smoky car capture system based on stereo monitoring

Abstract

The invention discloses a black-smoke car capturing system based on stereoscopic monitoring mode, which comprises a stereoscopic monitoring system of smoke degree, an intelligent video capturing system, an industrial computer and a server platform. The stereoscopic monitoring system of smoke degree and the intelligent video capturing system are connected with service platform through the industrial computer. The smoke stereoscopic monitoring system is used for stereoscopically scanning exhaust smoke of the vehicle, and the scanned image information is sent to the industrial computer; the intelligent video capturing system is used for capturing black smoke video, and the collected video information is sent to the industrial computer. The industrial computer calculates the smoke value and outputs the smoke density distribution diagram after image processing, and sends the capturing command to the intelligent video capturing system when the smoke value exceeds the standard, and carries on the license plate recognition to the video information. The black-smoke car capturing system based on stereoscopic monitoring has the function of capturing the evidence by the video, and has the advantages of accurately giving the smoke value and the opacity value of the automobile exhaust gas, realizing the capturing of the smoky car in the urban key area, reducing the exhaust emission of the urban high pollution motor vehicle and improving the urban air quality.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring instruments, in particular to a smoky car capture system based on a three-dimensional monitoring method. Background technique [0002] In recent years, the pollution of smoky vehicles has always been the focus and difficulty of motor vehicle environmental protection. A large amount of black smoke has caused serious harm to the human respiratory system and immune system. The research on the mutagenic and carcinogenic effects of motor vehicle exhaust pollution has always been a domestic One of the hotspots of related research. However, the phenomenon of black smoke emission from motor vehicles is relatively common, especially when diesel vehicles are starting, accelerating, going uphill, and overloading, which seriously affects the image of the city. The emission of black smoke mainly comes from diesel vehicles. These "black smoke" are the products of fossil fuel combustion, and th...

Problems solved by technology

This method mainly detects the characteristics of the rear of the vehicle in the video data to identify the black smoke vehicle, which is easily affected by the environment, weather, and light, resulting in a large number of false positives; on the other hand, due to the limitation of the algorithm, it can only identify the location of the exhaust pipe. rear car video

As a result, since the camera has no reference correction, the resulting Ringelmann blackness value is also prone to deviation

Finally, due to the limitation of the algorithm, it can only work during the day, and there will be false positives for vehicles that emit black smoke at night
