Embodiment Construction

[0035] Preferred embodiments of the present invention will be described in more detail below. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be embodied in various forms and should not be limited by the embodiments set forth herein.

[0036] Plume: A mass of gas expelled from an exhaust vent and dispersed into the air.

[0037] The smoky vehicle electronic capture system is a smoky vehicle electronic capture device that uses a camera to capture vehicle exhaust plumes at a certain speed and grades them. It is an intelligent application based on technologies such as the Internet of Things. It applies intelligent video technology to the monitoring of road vehicle exhaust pollution. It is a real-time monitoring system specially used to capture smoky vehicles driving on the road.

[0038] The smoky car electronic capture system uses high-definition cameras to obtain video and picture information o...

Abstract

The embodiment of the invention discloses a black smoke vehicle electronic snapshot system calibration method, which comprises the steps of setting a multi-level standard blackness plate, obtaining first measurement data of the black smoke vehicle electronic snapshot system for snapshot of the multi-level standard blackness plate, and obtaining a blackness level indication error of the black smokevehicle electronic snapshot system based on the first measurement data; and setting a set-level standard blackness plate, obtaining second measurement data of the set-level standard blackness plate captured by the black smoke vehicle electronic snapshot system, and obtaining blackness-level repeatability of the black smoke vehicle electronic snapshot system based on the second measurement data. The performance of the black smoke vehicle electronic snapshot system is calibrated through the two parameters, i.e., the blackness-level indication error and the blackness-level repeatability, and therefore the purpose of accurately calibrating the black smoke vehicle electronic snapshot system is achieved.

Description

technical field [0001] The invention belongs to the field of measurement verification, and more specifically relates to a method for calibrating an electronic capture system of a smoky car. Background technique [0002] At present, due to the rapid development of the motor vehicle industry, the number of motor vehicles in my country continues to grow, and the problem of motor vehicle emission pollution has become increasingly prominent, which has become one of the main sources of air pollution. Smoky vehicles are typical representatives of high-pollution vehicles, so black The prevention and control of tobacco truck pollution is imminent. At present, electronic capture systems for smoky vehicles based on image processing technology have been established in succession across the country. However, the existing smoky vehicle electronic capture system lacks a standard and accurate calibration method. Therefore, it is urgent to establish a calibration method for the electronic c...
