CAMERA CALIBRATION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

A camera calibration method, a camera calibration apparatus (300), an electronic device, and a computer-readable storage medium. The camera calibration method comprises: (202) when image sharpness is detected to be less than a sharpness threshold, acquiring a target infrared image and an RGB image respectively obtained by photographing the same scene with an infrared camera and an RGB camera; (204) extracting feature points in the target infrared image to obtain a first feature point set and extracting feature points in the RGB image to obtain a second feature point set, and matching the first feature point set and the second feature point set; and (206) obtaining, according to the matched feature points, a conversion relation between a coordinate system of the infrared camera and a coordinate system of the RGB camera.
