Embodiment

[0044] figure 1 It shows a flow chart of the first method for determining the occluded area of ​​a virtual object provided by the embodiment of the present application, the method is applied to a terminal device, and the terminal device is equipped with a camera for acquiring image data and a camera for acquiring depth information at the same time, The camera for obtaining image data may be an RGB camera, and the camera for obtaining depth information may be a time of flight (Time of flight, TOF) camera. The RGB camera and the TOF camera are used as examples below to illustrate, and the details are as follows:

[0045] Step S11, constructing a scene three-dimensional map of the current frame according to the feature points of the current frame and corresponding depth information;

[0046] In this step, after acquiring the current frame of the image through the RGB camera, extract the feature points of the current frame, estimate the pose of the current frame relative to the re...

Abstract

The invention is suitable for the technical field of software, and provides a method and device for determining a shielded area of a virtual object, and terminal equipment, and the method comprises the steps of constructing a scene three-dimensional map of a current frame according to the feature points of the current frame and corresponding depth information; if a click operation sent by a user on the scene three-dimensional map is detected, displaying a specified virtual object at a position corresponding to the click operation; constructing a three-dimensional scene model according to the feature point information of the current frame; comparing the depth values of the three-dimensional scene model and the virtual object model; determining a shielded area of the virtual object in the current frame according to a comparison result; and determining the shielded area of the virtual object in the next frame according to the shielded area of the virtual object in the current frame. Through the method, the operation speed of identifying the virtual object in the shielded area of the sequence frame can be greatly improved.

Description

technical field [0001] The present application belongs to the technical field of software, and in particular relates to a method, a device, a terminal device, and a computer-readable storage medium for determining an area where a virtual object is occluded. Background technique [0002] Augmented Reality (Augmented Reality, AR) is a new technology that can superimpose computer-generated virtual objects or system prompt information on real scenes to realize effective expansion and augmented reality of real scenes, and can support users to interact with them. [0003] In the process of using AR technology, the problem of occlusion consistency is involved. Consistency in occlusion requires virtual objects to be able to occlude the background and be occluded by foreground objects, and to have the correct virtual-real occlusion relationship. Only by correctly handling the front and rear positional relationship of virtual objects in the real world can users correctly perceive the...
