Abstract

The invention relates to a vehicle-mounted camera self-calibration method and device and a vehicle driving method and device, and the method comprises the steps: starting the self-calibration of a vehicle-mounted camera, and enabling a vehicle with the vehicle-mounted camera to be in a driving state; in the running process of the vehicle, collecting information required by self-calibration of thevehicle-mounted camera through the vehicle-mounted camera; and self-calibrating the vehicle-mounted camera based on the acquired information. According to the embodiment of the invention, the self-calibration process of the vehicle-mounted camera can be conveniently completed in the actual use environment of the vehicle-mounted camera under the condition that the use of the vehicle is not influenced, the calibration result is accurate, the calibration efficiency is high, and the application range is wide.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a vehicle-mounted camera self-calibration method and device, and a vehicle driving method and device. Background technique [0002] The traditional vehicle camera calibration method needs to manually calibrate a specific reference object under the set camera model, then perform image processing, and use a series of mathematical transformation formulas to calculate and optimize. The camera is calibrated. The traditional camera calibration method has strict requirements on the installation environment. Once the application scene is changed, it needs to be re-calibrated, which is time-consuming and laborious. Contents of the invention [0003] The present disclosure proposes a technical solution for self-calibration of a vehicle-mounted camera. [0004] According to an aspect of the present disclosure, a method for self-calibration of a vehicle camera is pr...
