Title: Camera parameter calibration method, device, apparatus, and system
Inventor: ZHANG KUI
IPC: G06T7/00
Filed: 2018-06-26
Abstract: Provided in embodiments of the present application are a camera parameter calibration method, device, apparatus, and system. The solution comprises: a camera captures an image of multiple checkerboard pattern targets to obtain a calibration image, i.e., the calibration image containing multiple checkerboard patterns; and a camera parameter is calculated on the basis of the calibration image containing the multiple checkerboard patterns. Firstly, the calibration image contains a plurality of checkerboard patterns, eliminating the need to acquire multiple calibration images of a checkerboard pattern target by adjusting the position and orientation of the checkerboard pattern target for multiple times, and hence improving calibration efficiency. Secondly, acquisition of calibration images by means of multiple capturing operations increases errors introduced by image capturing, and the present solution can be employed to reduce the capturing errors.
