A method and system for locating anchor points in augmented reality video images

Abstract

The present invention provides a positioning method for an anchor point in an augmented reality video screen, which is characterized in that it includes a positioning module, a video terminal and a display terminal; the positioning module is connected to the video terminal and the display terminal, and the positioning module includes a video stream interface input module, spatial position database, spatial registration and analysis module, and video image processing module; the method includes: S1: determining the object to be calibrated in the video; S2: creating the globally unique anchor point information of the object; S3: defining the The display style of the anchor object; S4: Obtain the video terminal information and the plane coordinates of the object to be anchored; S5: Analyze and identify the spatial position information of the anchor object; S6: Traverse the space of all anchor objects associated with the device ID Position; S7: Determine whether the anchor point object is added to the set to be rendered; S8: Traverse the anchor point object in the set to be rendered, and analyze its plane position; S9: Synthesize and send to the display terminal; S10: Display the video screen on the display terminal.

Description

technical field [0001] The invention relates to the technical field of computer video and vision, in particular to a positioning method and system for an anchor point in an augmented reality video image. Background technique [0002] Augmented reality (augmented reality, AR) technology is an emerging technology that superimposes computer-generated virtual objects on the real world seen by users, which improves users' perception of the real world and helps us better understand the real world, and Interact better with the real world. With the development of AR technology, [0003] People have higher and higher requirements for displaying elements in videos, and the types of displaying elements are also becoming more and more diverse. How to ensure the accurate display of elements and avoid confusing display of information is a huge challenge for video space positioning. [0004] In video augmented reality scenarios, the superposition of elements in the screen needs to be sp...

AI Technical Summary

Problems solved by technology

Especially when the position of the anchor point changes due to movement, the information may not be displayed accurately, affecting the sense of reality and user experience

In addition, in order to ensure the calibration efficiency of the anchor point, in the existing AR display system, the information of the anchor point is usually stored in the terminal video acquisition device. When the terminal device is damaged, the anchor point will be lost, and the information display cannot be determined.
