Abstract

The invention provides a method for carrying out transparent processing on an image background, the method is executed by an unreal engine, and the method comprises: writing a rendering result of a target object into a target texture which can be accessed across processes based on a specified trigger signal, and generating a target texture handle, the background color of the rendering result being transparent; and writing the target texture handle into a memory which can be accessed across processes, so that other processes can read the target texture handle, and based on the target texture handle, accessing the target texture of the unreal engine to generate an image which contains a target object and has a transparent background color.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method, device, live broadcast system, electronic equipment, and computer-readable storage medium for transparently processing an image background. Background technique [0002] In live broadcast application scenarios, in some cases, it is necessary to perform background removal on the current frame image, that is, to retain the target object in the current frame and transparently process the rest. In related technologies, if the live image produced based on the Unreal Engine needs to be transparent, it is generally realized by using a green screen cutout at the broadcast end: the chroma key function based on the open source software OBS (Open Broadcaster Software) will remove the target The background outside the object is set to pure green, and then the color of the pure green area is set to transparent to achieve the purpose of background removal.
