Self-calibration method and system of motor vehicle exhaust monitoring system, equipment and medium

The invention provides a self-calibration method and system for a motor vehicle exhaust monitoring system, equipment and a medium. The method comprises the steps: acquiring detection pictures collected by a shooting device; acquiring position information of reference points in the detection pictures and initial position information of the reference points; calculating first offset data of a camera module in the shooting device according to the initial position information of the reference points and the position information in the detection pictures; and if the offset angles in the first offset data in the continuous preset number of detection pictures are all greater than the first angle threshold value and/or the offset displacements are all greater than the first displacement threshold value, sending a camera module reset instruction to the shooting device to correct the camera module. The shooting angle of the camera module can be automatically monitored and corrected in time, manpower is reduced, all-wea
