Problems solved by technology

However, since the feature parts of different users are different when performing live video broadcast, and because the angle of video shooting is also constantly changing during the live video broadcast, when the virtual props are worn on the live video, the virtual props are very difficult. It is difficult to accurately superimpose with the corresponding feature parts, and the user experience is not high

Abstract

The embodiment of the invention provides an image processing method and device. The method comprises the steps of after a system receives a virtual item material mapping instruction, capturing an area where a target face locates in a current video bitstream to obtain the target face; marking the target face area to generate multiple target marking points, and obtaining coordinates corresponding to the target marking points; calculating a view angle affine transformation matrix according to the coordinates of the target marking points and a standard marking point coordinate of a standard face; then calculating a target virtual item material and the coordinate thereof corresponding to the target face according to the view angle affine transformation matrix and the standard virtual item material and corresponding coordinate thereof; and mapping the target virtual item material to the current video bitstream, thereby finishing the mapping of a target virtual item. By applying the image processing method and device provided by the invention, the superposition accuracy between a virtual item and a corresponding part when the virtual item is worn in a live video can be improved; and thus, the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] With the rapid development of Internet technology and the substantial increase in Internet speed, Internet video live streaming has emerged. Internet live video broadcasting is different from traditional radio and television live video broadcasting. During the process of Internet video live broadcasting, user feedback information can be received through the Internet and loaded into the information source, which improves the viewing and interactivity of video live broadcasting. Therefore, Internet video live broadcasting It has been widely accepted and loved by people. [0003] At present, Internet live video broadcasts mostly use virtual props as the carrier of live video interaction. During live video broadcasting, the client sends an instruction to wear virtual props to the server through the...
