Abstract

The present application provides a multi-camera calibration method, device, storage medium and electronic device. The method includes acquiring a first image captured by some cameras of a calibration object; using the first image to calibrate some cameras, and simultaneously acquiring other camera pairs The second image captured by the calibration object is used to calibrate other cameras, and some cameras and other cameras together form multiple cameras. The present application can effectively shorten the multi-camera calibration time and improve the calibration efficiency.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a multi-camera calibration method, device, storage medium and electronic equipment. Background technique [0002] While mobile terminals bring convenience to people's daily photography, people have higher and higher requirements for the quality of the captured images. Therefore, it is necessary to determine the parameters of the camera during the manufacturing process of the mobile terminal to calibrate the camera. Assist in better follow-up imaging. [0003] In the related art, since the current mobile terminal only has two image signal processors, when the mobile terminal is equipped with multiple cameras, for example, 4 cameras, if it is necessary to calibrate the extrinsic parameter matrix between camera 1 and the other 3 cameras , the commonly used calibration method is: first calibrate camera 1 and camera 2, then calibrate camera 1 and camera 3, and ...
