Abstract

The present invention provides an image correction method, device, electronic equipment, and computer-readable storage medium. The method obtains the offset of the camera when the camera shakes; wherein, the structured light module has Optical image stabilization mode; adjust the deflection angle of the projector according to the calibration function and the offset of the camera, and simultaneously acquire the depth image collected by the camera; acquire the deflection angle according to the offset and the deflection angle Reference depth information of the depth image; correcting the depth image according to the reference depth information. Solved the problem of large errors in the depth information obtained by the camera during the process of taking pictures or previewing with the structured light module. By using the reference depth information to correct the depth image, the depth image acquired by the structured light module can be corrected. Improve the accuracy of depth information acquisition, and then achieve precise focusing on the shooting object.

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 ...
