Method and terminal device for determining occluded area of virtual object

A terminal device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor is configured to execute the computer program to perform:

• constructing a scene three-dimensional map of a current frame according to features points of a current frame and corresponding depth information thereof, and constructing a three-dimensional scene model according to the features points of the current frame;
• displaying a designated virtual object at a location corresponding to a click operation, in response to detecting the click operation of a user on the scene three-dimensional map;
• comparing depth values of the three-dimensional scene model with depth values of a model of the virtual object, and acquiring a comparing result;
• determining an occluded area of the virtual object in the current frame according to the comparing result;
• and
• determining another occluded area of the virtual object in a next frame following the current frame according to the occluded area of the virtual object in the current frame, in response to a pair number of feature points in the next frame, which matches with the feature points of the occluded area of the virtual object in the current frame, being greater than or equal to a preset matching pair threshold.

A computer-readable non-transitory storage medium storing computer program, wherein the computer program when executed by a processor to perform:

• constructing a scene three-dimensional map of a current frame according to features points of a current frame and corresponding depth information thereof;
• displaying a designated virtual object at a location corresponding to a click operation, in response to detecting the click operation of a user on the scene three-dimensional map;
• constructing a three-dimensional scene model according to the features points of the current frame;
• comparing depth values of the three-dimensional scene model with depth values of a model of the virtual object, and acquiring a comparing result;
• determining an occluded area of the virtual object in the current frame according to the comparing result;
• and
• determining another occluded area of the virtual object in a next frame following the current frame according to the occluded area of the virtual object in the current frame, in response to a pair number of feature points in the next frame, which matches with the feature points of the occluded area of the virtual object in the current frame, being greater than or equal to a preset matching pair threshold.
