Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] refer to figure 1 , figure 1 is a schematic diagram of the virtual environment provided by the embodiment of the present invention.

[0051] In the virtual environment, the chaser encounters inaccessible obstacles and accessible buildings. The thick dotted line in the figure is the peripheral path and entrance path set in advance by the building, and the thin dotted line is the chasing route dynamically and autonomously generated by the chaser. , the ...

Abstract

The invention provides a method and system for environmental perception simulation of a virtual human. The method comprises the steps that the virtual human and a target chased by the virtual human are created, so that the position and the speed of the virtual human are determined; binocular vision is achieved; according to the speed of the virtual human, the binocular vision is periodically sent to the target chased by the virtual human and according to the binocular vision, information of barrier impact points in the environment where the virtual human is located and a preset behavior inference knowledge base, chasing motion of the virtual human is determined; the chasing motion of the virtual human is executed, so that the purposes that the virtual human percepts the chased target and determines a chasing path actively in the dynamic virtual environment which is not completely known are achieved.

Description

technical field [0001] The invention relates to the field of virtual reality technology and digital simulation, in particular to a simulation method and system for virtual human environment perception. Background technique [0002] Perception model is the basis for intelligent virtual human to understand the surrounding environment and carry out autonomous behavior control. Ergonomic research shows that more than 80% of human perception of the external world comes from vision. Therefore, the realization of virtual vision sensors is the basis of perception models. At present, visual perception models can be divided into four methods: (1) Completely simulate human The principle of visual perception, a visual perception model based on image rendering. However, due to the immature development of image recognition technology, this method cannot meet the requirements of real-time perception in terms of accuracy and speed; (2) based on the visual perception model of the scene data...
