Abstract

The invention provides a multi-camera calibration method and device, a storage medium and an electronic device, and the method comprises the steps: obtaining an image, obtained through the simultaneous photographing of a calibration object through all cameras, and the calibration object comprising a target feature point; determining a target feature point corresponding to the image coordinate datain each image; and according to the image coordinate data and the space coordinate data of the target feature point, determining parameters of a camera for calibration, the space coordinate data being coordinate data of an actual space position in a world coordinate system. According to the invention, the joint calibration of the plurality of cameras can be efficiently completed in a manner thatthe plurality of cameras shoot only one image at the same time, the calibration time of the plurality of cameras is effectively shortened, the calibration accuracy is ensured, and the calibration efficiency is improved.

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 related technologies, the calibration is generally performed by taking multiple groups of images on a two-dimensional plane calibration chart, detecting feature points on the images, and then calculating camera parameters. [0004] In this way, when there are multiple cameras on the mobile terminal, it takes a long time and the calibration efficiency is low. Contents of the invention [0005] Th...
