The invention relates to the technical field of camera calibration, in particular to a camera calibration method and system, terminal equipment and a computer readable storage medium. The camera calibration method is applied to the camera calibration system. The method comprises the following steps: controlling a first driving mechanism to drive a calibration object to move to any sampling position; the second driving mechanism is controlled to drive the camera to move to a plurality of expected sampling poses, so that the calibration object is located at different positions in the view field range of the camera; the camera is controlled to shoot the calibration object located at the sampling position according to the multiple expected sampling poses, so that an image sequence of the calibration object is obtained; and obtaining a calibration result of the camera based on the image sequence. The method is wide in practicability, high in expansibility and high in calibration efficiency.
Description
technical field [0001] The present application relates to the technical field of camera calibration, and in particular, to a camera calibration method, system, terminal device, and computer-readable storage medium. Background technique [0002] Camera calibration is mainly used to determine the relationship between the three-dimensional geometric position of a point on the surface of the object and its corresponding point in the image, so as to correct the image captured by the camera and obtain an image with relatively small distortion. Whether in image measurement or machine vision applications, the calibration of camera parameters is a very critical link. The accuracy of the calibration results and the stability of the algorithm directly affect the accuracy of the results produced by the camera work. Camera calibration includes solving the camera's intrinsic parameter matrix and extrinsic parameter matrix. Intrinsic parameter matrix Among them, α and β are the effectiv...
