Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] The positioning mark of the embodiment of the present invention can be applied to a variety of different position tracking systems or position positioning scenarios, for example, in virtual reality, tracking and positioning the position of the user's head, hands or other specific body torso in the three-dimensional space .

[0050] Here, the term "circular" is used to indicate a closed or unclosed circular pattern that is connected end to end and occupies a certain area, such as a circular ring, a square ring, a rectangular ring, other polygonal rings, or other irregular shapes. Circular pa...

Abstract

The embodiments of the invention disclose a positioning identification and a positioning method thereof. The positioning identification comprises at least four identification mark points; and an annular encoding point which comprises two or more than two annular patterns used for storing number information of the identification mark points, wherein the number information is expressed through one or multiple pieces of data, each annular pattern is composed of one or more pattern units according to a predetermined splicing sequence, and each pattern unit is provided with at least one graphic feature used for distinguishing the pattern units so as to store one piece of data. The information storage capacity of original annular encoding is expanded, compared to a conventional two-dimensional code storage mode, the encoding mode is simple, the information reading speed is fast, the identification mark points and encoding points are also separated, and the positioning accuracy is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of position tracking, in particular to a positioning mark and a positioning method thereof. Background technique [0002] With the continuous development of electronic equipment technology, immersive display methods with a stronger sense of reality and good user experience, such as virtual reality, augmented reality, and three-dimensional panoramic video, have been greatly developed and have strong application requirements. [0003] In such an immersive display mode, determining the position and changes of the current user or specific objects (such as the user's head and hands) in the virtual world is a very important part of ensuring a good user experience. A location tracking system based on different principles to realize its positioning function. [0004] Generally, the tracking system is mainly implemented based on the following two different principles. One is a fixed extern...
