Black smoke vehicle electronic snapshot system calibration method

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...
