MULTI-CAMERA ZOOM CONTROL METHOD AND APPARATUS, AND ELECTRONIC SYSTEM AND STORAGE MEDIUM

WIPO Patent Application WO/2021/208371

A1

Provided are a multi-camera zoom control method and apparatus, and an electronic system and a storage medium. The method comprises: in the process of a first camera collecting an image, if the current set magnification input by a user is in a magnification transition zone, starting a second camera; acquiring a corresponding stereo correction matrix on the basis of calibration parameters of the first camera and the second camera; calculating a translation matrix on the basis of an acquired pixel position correlation between the same content regions of interest that correspond to a first zoomed image and a second zoomed image and in combination with the current set magnification, and then calculating a smooth transition transformation matrix in combination with the stereo correction matrix; and performing, by applying the smooth transition transformation matrix, affine transformation on an image output by the first camera, so as to obtain a display image of a device. According to the method, a stable translation quantity is obtained in a region of interest by means of template matching and on the basis of the stereo correction and alignment of an image, so as to realize the smooth transition of the region of interest, thereby improving the alignment stability of the region of interest.
