Abstract

A double-camera calibration method comprises: collecting a first image and a second image of the same calibration plate combination through double cameras, wherein the calibration plate combination comprises three or more calibration plates, and the calibration plates are arranged according to a preset angle; segmenting the first image and the second image according to the positions of the calibration plates in the first image and the second image to obtain more than three image pairs with different placement angles of the calibration plates; and performing dual-camera calibration according tothe obtained more than three image pairs. According to the positions of the calibration plate in the first image and the second image, after the first image and the second image are segmented, threegroups or more than three groups of image pairs can be obtained through one-time shooting, so that the dual cameras can be calibrated through one-time shooting, the shooting times can be reduced, andthe calibration efficiency can be improved.

Description

technical field [0001] The present application belongs to the field of cameras, and in particular relates to a dual camera calibration method, device and equipment. Background technique [0002] In order to improve the quality of images captured by the cameras of the smart terminals, dual cameras are often installed on the smart terminals. After the binocular camera is calibrated, with the corresponding registration, depth estimation or enhancement algorithm, the smart device can realize functions such as optical zoom, dual-camera blurring, dark-light night shooting, etc., which improves the user experience. [0003] When calibrating dual cameras, at present, professional calibration equipment such as dots, checkerboards or two-dimensional code checkerboards are generally used, and algorithms such as Zhang Zhengyou’s calibration method can be used to obtain ideal distortion model parameters (internal parameters) and cameras. The positional relationship between (external par...
