Abstract

The invention provides a multi-camera calibration method and device, a storage medium and electronic equipment. The electronic equipment comprises a plurality of cameras, the plurality of cameras arean ultra-wide-angle camera, a wide-angle camera and a long-focus camera. The method comprises the following steps: based on different angles, obtaining images obtained by simultaneously shooting a calibration object by each camera, wherein the calibration object comprises a target feature point; determining a target feature point corresponding to the image coordinate data in 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. The plurality of cameras can calibrate the calibration object at the same time, the calibration angles are multiple, the calibration execution time isshortened, the calibration errors are reduced, and the calibration efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to a multi-camera calibration method, device, storage medium and electronic equipment. Background technique [0002] Camera calibration is to obtain the internal and external parameters of the camera. When the camera is used for imaging, the pre-calibrated internal and external parameters are used to map the object to be photographed from the three-dimensional world to the imaging plane of the camera for imaging. [0003] In the related art, when the mobile device terminal has three cameras of super wide-angle, wide-angle and telephoto, the ultra-wide-angle and wide-angle cameras are used for calibration, and the telephoto and wide-angle cameras are calibrated respectively. [0004] In this way, when performing calibration, the dual camera needs to be calibrated twice, which takes a long time and the calibration efficiency is low. Contents of the inventi...
