Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0034] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first pixel point could be termed a second pixel point, and, similarly, a second pixel point could be termed a first pixel point, without departing from the scope of the present application. Both the first pixel and the second pixel are pixels, but they are not the same pixel.

Abstract

The invention relates to an image processing method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps of: obtaining a sample; obtainingan initial depth image collected by a depth camera and a confidence map corresponding to the initial depth image; acquiring a color image by the color camera; obtaining an initial depth value corresponding to a first pixel point in the initial depth image, obtaining a confidence coefficient map of a first pixel point and a confidence coefficient value of a second pixel point corresponding to the first pixel point in the confidence coefficient map, obtaining a brightness value of a third pixel point corresponding to the first pixel point in the color image, determining a confidence coefficientthreshold of the first pixel point based on the brightness value, and determining that an initial depth value is effective when the confidence coefficient value is greater than or equal to the confidence coefficient threshold. The confidence coefficient threshold value can be determined according to the brightness of the corresponding pixel point in the color image, and whether the depth information of the corresponding pixel point in the depth image is effective or not is determined according to the confidence coefficient threshold value, so that the accuracy of the depth information can be improved.

Description

technical field [0001] The present application relates to the field of image technology, in particular to an image method, device, electronic equipment and computer-readable storage medium. Background technique [0002] The electronic device can collect the depth information of the object to be photographed through the depth camera, and then perform processing such as live body detection, three-dimensional modeling, and background blurring on the image according to the depth information. The depth camera can output the initial depth image of the object to be photographed and the corresponding confidence map, and the electronic device can filter the initial depth image according to the confidence map, so as to obtain the effective depth value of the initial depth image. However, there is a problem that the obtained depth information is not accurate enough in the traditional method. Contents of the invention [0003] Embodiments of the present application provide an image p...
