Embodiment 1

[0033] Such as figure 1As shown, the application scene of the embodiment of the present application is specifically a virtual reality scene, and the virtual reality scene is composed of a virtual character, a virtual environment and a semantic path. There may be multiple semantic paths in a virtual reality scene, wherein the semantic path is a virtual character A medium for interacting with virtual environments.

[0034] Specifically, the semantic path is a trajectory drawn on the geometric figure of the virtual environment and composed of nodes and directed connections between nodes, wherein the information of nodes at least includes node position information and node environment information of nodes. Specifically, the directed connection constitutes information about the direction and distance that each node can depart and enter; the node position information records the coordinate information of the node on the virtual environment; the node environment information records t...

Embodiment 2

[0110] The embodiment of the present application also provides a target tracking device, such as Figure 4 As shown, for ease of description, only the part relevant to the embodiment of the present application is shown:

[0111] The target tracking device can be a device composed of a virtual character (a computing entity controlled by the computing unit of the terminal device and displaying its image, position and behavior on the display unit) or part of the hardware of the virtual character. The target tracking device includes: going to the node Determining unit 41, going to unit 42, path routing unit 43 and moving unit 44, wherein:

[0112] The going-to node determination unit 41 is used to determine the path node closest to the virtual character as the going-to node according to the starting position of the virtual character, wherein the path node is a node on a preset semantic path in a virtual reality scene; The semantic path is a trajectory drawn on the geometric figur...

Embodiment 3

[0136] Figure 5 It is a schematic diagram of a terminal device provided by an embodiment of the present invention. Such as Figure 5 As shown, the terminal device 5 of this embodiment includes: a processor 50, a memory 51, and a computer program 52 stored in the memory 51 and operable on the processor 50, such as a virtual reality scene interaction program. When the processor 50 executes the computer program 52, the steps in the above-mentioned embodiments of the virtual reality scene interaction method are implemented, for example figure 2 Steps S201 to S204 are shown. Alternatively, when the processor 50 executes the computer program 52, it realizes the functions of the modules / units in the above-mentioned device embodiments, for example Figure 4 Function of units 41 to 44 shown.

[0137] Exemplarily, the computer program 52 can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 51 and executed by the processor 50 to ...

Abstract

The invention discloses a target tracking method and device, terminal equipment and a storage medium. The target tracking method comprises the steps of determining a path node closest to a virtual character as a running node according to an initial position of the virtual character; moving to the rushing node until the rushing node is reached; according to the path node where the current virtual character is located, the path node which is closest to the tracked target at present and a pre-stored path routing matrix, the virtual character is obtained; determining a next path node to be reachedby the current virtual character, wherein the path routing matrix is a matrix storing an optimal next path node from a first path node to a second path node; and moving to the next path node so as toapproach the tracked target. According to the embodiment of the invention, the target tracking efficiency of the virtual character in the virtual reality scene can be improved.

Description

technical field [0001] The present application belongs to the technical field of virtual reality, and in particular relates to a target tracking method, device, terminal equipment and storage medium. Background technique [0002] Existing virtual reality scenes usually consist of virtual characters and virtual environments. A virtual character refers to a three-dimensional model with a human image, an animal image, or an artificially designed phantom image (such as a flying dragon) simulated through virtual reality technology, which can simulate the perception and behavior of humans or animals. [0003] Object tracking is a typical task performed by existing avatars in virtual reality scenarios. In the existing virtual reality scene, the virtual environment may change with time, or may change due to the influence of the action of the virtual character on the virtual environment and other dynamic factors, that is, the virtual environment in the virtual reality scene is An u...
