INFRARED POSITIONING METHOD, INFRARED POSITIONING APPARATUS, AND INFRARED POSITIONING SYSTEM

摘要

An infrared positioning method, an infrared positioning apparatus, and an infrared positioning system. The method comprises: performing, on the basis of an object image, infrared point recognition processing on an object to be positioned to obtain infrared point information corresponding to said object, wherein the infrared point information comprises coordinate data of three infrared points, and the three infrared points are distributed in a shape of an isosceles triangle (S101); recognizing the vertices of the isosceles triangle and the midpoint of the bottom edge according to the coordinate data of the three infrared points, and generating, according to the vertices of the isosceles triangle and the midpoint of the bottom edge, a direction vector pointing to the vertices, the direction vector representing the movement direction of the object to be positioned (S102); and calculating a vector included angle between the direction vector of the object to be positioned and a preset coordinate system in a virtual environment, and determining, according to the vector included angle, the current movement direction of the object to be positioned (S103). By means of the method, a user can discern the direction even when immersing in the virtual environment, thereby enhancing the immersion of the user in the virtual environment; and the interaction between a person and a person or between a person and an object in the virtual environment is achieved, thereby satisfying the interaction requirement of the user in the virtual environment.
