Abstract

The invention provides an image correction method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining the offset of a camera when thecamera shakes, Wherein the structured light module has an optical image stabilization mode; Adjusting the deflection angle of the projector according to a calibration function and the offset of the camera, and synchronously acquiring a depth image acquired by the camera; Obtaining reference depth information of the depth image according to the offset and the deflection angle; And correcting the depth image according to the reference depth information. The problem that errors of depth information obtained by a camera are large in the photographing or previewing process of the structured lightmodule is solved. The depth image is corrected by using the reference depth information, so that the depth image acquired by the structured light module is corrected. Therefore, the accuracy of depthinformation acquisition is improved, and the accurate focusing of the shot object is realized.

Description

technical field [0001] The present application relates to the field of information technology, in particular to an image correction method, device, electronic equipment and computer-readable storage medium. Background technique [0002] In the field of electronic technology, depth information refers to information related to the vertical distance between a lens (Lens) of a camera module in an image acquisition device and an object to be photographed. After obtaining the depth information, the camera module can control the movement of the Lens according to the depth information, so as to realize the focus on the shooting object. Therefore, the accuracy of focusing depends on the accuracy of the depth information acquisition. Optical Image Stabilization (OIS) is a technology that relies on special lenses and photosensitive elements to minimize image instability caused by shaking during use by the operator. OIS is mainly realized by moving the lens. [0003] However, when the ...
