Problems solved by technology
[0003] In related technologies, it takes a period of time for the video frame to be transmitted to the application program after the camera collects the video frame, resulting in a large deviation between the time point when the application program obtains the video frame and the time point when the video frame is actually collected by the camera. The attitude data corresponding to the time point of the video frame is used to determine the target position in the video frame, then the accuracy of the determined target position is low, which leads to the shaking phenomenon of the avatar in the video when the camera collects the video during the movement process Seriously, the display effect is poor

The invention provides a virtual image display method and device, a terminal and a storage medium, and belongs to the technical field of computers. The method comprises the steps that a target video frame output by SurfaceText is obtained through an application program, and the target video frame is obtained by processing an original video frame currently collected by a camera; a getTimeStamp of the SurfaceText is called through the application program, a first timestamp is obtained, and the first timestamp is used for representing a time point when the SurfaceText is processed to obtain the target video frame; and through the application program, attitude data corresponding to the camera is determined at the first timestamp, a target position in the target video frame is determined based on the attitude data, and the virtual image is displayed at the target position. The jitter degree of the virtual image in the video can be relieved under the condition that the camera collects the video in the moving process, so that the display effect of the virtual image is improved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a virtual image display method, device, terminal and storage medium. Background technique [0002] Augmented reality (Augmented Reality, AR) can use computer graphics technology and visualization technology to construct a virtual image that does not exist in the real environment, and integrate the virtual image into the video corresponding to the real environment, and present the video after the fusion of the virtual image to the user. , to provide users with an environment with real sensory effects. When integrating the avatar into the video corresponding to the real environment, it is necessary to determine the target position for displaying the avatar in the video frame, and display the avatar at the target position. [0003] In related technologies, it takes a period of time for the video frame to be transmitted to the application program after the camera collect...
