Depth image restoration method and device, electronic equipment and computer storage medium

Abstract

The invention provides a depth image restoration method and device, electronic equipment and a computer storage medium, and the method comprises the steps of obtaining a depth image and an infrared image obtained through photographing a target object; determining a target depth area and a target infrared area where a target object is located in the depth image and the infrared image; obtaining a difference between the target depth region and the target infrared region in the depth image to obtain a to-be-restored region; selecting a pixel point adjacent to the repaired pixel point or the edgeof the target depth area in the to-be-repaired area as a to-be-repaired pixel point, updating the depth value of the to-be-repaired pixel point to a weighted average value of the depth values of the adjacent repaired pixel point and the pixel point located in the reference area, and obtaining a repaired pixel point, and then selecting new pixel points to be restored until all the pixel points in the area to be restored are restored. According to the scheme, the infrared image is used for determining the to-be-restored area and restoring the pixel points in the to-be-restored area, so that missing of the depth image is eliminated.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a restoration method, device, electronic equipment and computer storage medium of a depth image. Background technique [0002] A depth map is a special image captured by a depth camera with a depth measurement function. Similar to an ordinary planar image, a depth map is also composed of multiple pixels, but the value corresponding to each pixel of the depth map is a depth value. , the depth value of a pixel is used to indicate the distance from the corresponding spatial point of the pixel on the real object to the imaging plane of the depth camera, and a more three-dimensional image can be obtained by using the depth map. [0003] The depth map captured by the current depth camera is often missing at the edge of the object, resulting in the edge of the object is not smooth enough, and the accuracy of the depth map is poor.
