Image synthesis method and device, terminal equipment and readable storage medium

Abstract

The invention provides an image synthesis method and device, terminal equipment and a readable storage medium. The method is applied to a data transmission system. The data transmission system comprises an anchor end, a server and a playing end. According to the method, a data transmission mode between devices in a live broadcast scene is improved, a server obtains background image data under each real view angle before live broadcast is started, and an anchor end obtains foreground image data under each real view angle in real time in the live broadcast process; and the playing end synthesizes a virtual view angle image under the view angle to be watched according to the background image data and the foreground image data. According to the method, part of original work of the server is allocated to the anchor end and the playing ends to be executed, on one hand, the workload of synthesizing the image by the server is reduced, the working efficiency of the server is improved, on the other hand, the plurality of playing ends can synthesize respective live broadcast images to be played in parallel, so that the image synthesis efficiency is further improved, and the user experience is improved. And the live broadcast watching experience of the user is enhanced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image synthesis method, device, terminal equipment and readable storage medium. Background technique [0002] In a video shooting scene, in order to better shoot a video, usually multiple camera equipments are arranged around the shooting point. However, this layout method requires more camera equipment, which increases the workload of camera equipment installation, calibration, debugging, and data transmission synchronization. In the related art, a free viewing angle synthesis algorithm is used to synthesize a virtual viewing angle image of a viewing angle without the camera equipment installed by using the real image collected by the camera equipment, thereby reducing the deployment quantity of the camera equipment. However, if the above-mentioned free view synthesis algorithm is directly applied to the network live broadcast scene, that is, the live broadc...

Problems solved by technology

However, if the above-mentioned free view synthesis algorithm is directly applied to the network live broadcast scene, that is, the live broadcast image is collected by the host end, the server synthesizes the virtual view image from the view angle without camera equipment based on the live broadcast image, and the synthesized virtual view image is played by the player end. Perspective image, image synthesis efficiency is not high
