Calibration method, device, storage medium and terminal equipment of an adas camera

Abstract

A calibration method for an ADAS camera is used to solve the problems of high cost and complicated operation of the current ADAS camera calibration method. The method includes: measuring the installation height of the target camera on the vehicle, and the vehicle is placed on a flat ground; determining the first position of the target camera perpendicular to the ground; placing a calibration mark in the shooting area in front of the target camera The calibration plate is provided with a scale; the distance between the first position and the placement position of the calibration plate is measured to obtain the placement distance of the calibration plate; after starting the target camera, it is determined that the calibration line in the display screen of the ADAS falls The current scale on the calibration board; read the calibration distance corresponding to the current calibration line; determine the target of the calibration line on the calibration board according to the installation height, the placement distance of the calibration board and the calibration distance Scale: adjusting the shooting angle of the target camera so that the calibration line moves from the current scale to the target scale.

Description

technical field [0001] The present invention relates to the technical field of camera calibration, in particular to a calibration method, device, storage medium and terminal equipment for an ADAS camera. Background technique [0002] At present, there are mainly the following methods for the calibration of vehicle ADAS (Advanced Driver Assistant Systems, Advanced Driver Assistance Systems) cameras: designing high-precision calibration boards through complex instruments or methods, combining multiple sensors for measurement and calibration, and developing special cameras Calibration software, etc. [0003] However, although these existing calibration methods can complete the calibration of ADAS cameras, they often have disadvantages such as high cost, the need to develop special calibration software, long development cycles, and complicated operations, which makes ADAS camera calibration difficult to popularize and limited in application. . Contents of the invention [00...
