A positioning system for ar/mr technology

Abstract

The present invention relates to the technical field of AR / MR space computing, and in particular to a positioning system for AR / MR technology. The positioning system includes a real scene unit and equipment, a node system and a virtual scene unit are established in the equipment, and the equipment is equipped with a camera; The device can be positioned by a single recognition point; the real scene unit includes reference object A and reference object B, and the virtual scene unit includes reference object a and reference object b; the node system includes global nodes, and global nodes include global total nodes, global displacement nodes and global rotation Node, its parent-child order is: global total node-global displacement node-global rotation node; reference object a belongs to the child object of the total node in the node system. The positioning system can use multiple nodes and multiple reference objects to accurately locate complex scenes as a whole and multiple positioning targets in the scene.

Description

technical field [0001] The present invention relates to the technical field of AR / MR space computing, in particular to a positioning system for AR / MR technology. Background technique [0002] Augmented Reality (AR for short) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen. the real world and interact with it. This technique was proposed in 1990. With the improvement of the CPU computing power of portable electronic products, it is expected that the application of augmented reality will become more and more extensive. [0003] Mixed reality technology (referred to as MR) is a further development of augmented reality technology. It is generally believed in the industry that the difference from augmented reality is that the display screen and virtual screen of augmented reality are mixed and displayed on the screen, w...

AI Technical Summary

Problems solved by technology

The shortcoming of this method is: 1, scanning time is long

2. There will be jitter caused by periodic automatic calibration

3. The positioning accuracy is not high

4. It consumes a lot of equipment computing power when scanning the scene

5. Unable to actively adjust according to user needs

6. It is difficult to judge whether the positioning is accurate

The shortcoming of this method is: 1, scanning time is long

2. It consumes a lot of equipment computing power when scanning the scene

3. Poor positioning accuracy

4. Unable to calibrate complex scenes

5. It is difficult to judge whether the positioning is accurate

The disadvantages of this method are: 1. The positioning accuracy is not high

2. It can only be used for a single reference object. The farther the other reference objects to be identified are from this single reference object, the worse the accuracy will be.

3. It is difficult to judge whether the positioning is accurate

Due to the deviation that may be caused by the inaccurate positioning of traditional methods, the indications of buttons and signs are misplaced, just like Figure 10 , the virtual arrow points to the button ④, and the virtual high temperature mark deviates from the dotted line box to represent the high temperature position of the device

thus misleading users
