Depth image obtaining method and device, electronic equipment and storage medium

Abstract

The invention provides a depth image obtaining method and device, electronic equipment and a storage medium, and relates to the technical field of image processing, and the method comprises the steps:obtaining a first number of groups of initial brightness images collected by image collection equipment for a to-be-detected object, wherein the brightness of each group of initial brightness imagesis the same; synthesizing the obtained initial brightness graphs to obtain a second number of combined brightness graphs, with each combined brightness graph being obtained by synthesizing one or moregroups of initial brightness graphs, and the number of the initial brightness graphs adopted for synthesizing each group of combined brightness graphs being different, with the second number being greater than or equal to 2; according to a preset fusion rule, fusing the disparity maps obtained on the basis of each combined brightness map to obtain a fused disparity map, and obtaining a depth image of the to-be-measured object on the basis of the fused disparity map; or, according to a preset fusion rule, fusing the initial depth maps obtained on the basis of each combined brightness map to obtain a depth image of the to-be-measured object. The efficiency of obtaining a depth image with a high dynamic range can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a depth image acquisition method, device, electronic equipment and storage medium. Background technique [0002] In the application scenario of 3D detection, in order to obtain the depth information of the object to be measured, it is usually necessary to use an image acquisition device to obtain a depth image of the object to be measured, and in order to improve the quality of the depth image, it is usually necessary to obtain a depth image with a high dynamic range. [0003] In the prior art, the invention patent application "High Dynamic Range Depth Generation for 3D Imaging System" with application publication number CN108702437 records that when obtaining a high dynamic range depth image, it is usually necessary to use image acquisition equipment according to different The exposure time collects multiple frames of images, and restores the depth information o...

Problems solved by technology

[0004] Although it is possible to obtain depth images with a high dynamic range by using the existing technology, when multiple frames of images are collected according to different exposure time lengths, the frame rate of the collected images will be reduced due to the change of the exposure time of the image acquisition equipment, thereby reducing the high Acquisition efficiency of depth images with dynamic range
