Abstract

The invention relates to the technical field of optics, and discloses a camera calibration method, which comprises the following steps: acquiring a calibration image shot by a to-be-calibrated camera; determining an effective calibration area for camera calibration in the calibration image; when the effective calibration area meets a preset condition, determining that the calibration image is an effective calibration image; wherein the preset condition is determined according to a specified calibration area of the to-be-calibrated camera; and carrying out camera calibration on the to-be-calibrated camera based on the effective calibration image. According to the camera calibration method provided by the invention, the camera can be calibrated based on the effective calibration image, the accuracy of the camera calibration structure is improved, and the camera calibration effect is optimized. The invention further discloses a camera calibration device.

Description

technical field [0001] The present application relates to the field of optical technology, for example, to a camera calibration method and device. Background technique [0002] During the camera calibration process, the camera can obtain calibration images by shooting the calibration plate, and then obtain relevant parameters of the camera by analyzing the calibration images. Subsequently, the camera can also be calibrated based on the result of camera calibration. Therefore, the quality of the calibration image has a great influence on the camera calibration results and the effect of camera calibration. [0003] In the related art, there may be various problems in the calibration image taken by the camera, such as the calibration plate is too small, the position of the calibration plate does not meet the requirements, etc. These problems often lead to low accuracy of the calibration result, thereby affecting the camera calibration effect.
