Problems solved by technology

[0004] However, there is a certain lag in the tracking and registration of moving objects in augmented reality technology at present. The main reason is that there is a delay in determining the information of moving objects.
The reasons for the delay of moving object information are: (1) In one method, the camera continuously acquires images within a certain range around the current moving object and the position of the moving object, and then compares adjacent frame images to obtain moving object information. The information involved in this method is complex, which reduces the timeliness of obtaining information on moving objects; or, (2) in another method, using a variety of sensors to obtain motion information of moving objects, but due to some sensors It has the characteristic of long delay, so that the acquired data has a certain delay

Embodiment 1

[0111] A method for quickly and real-time obtaining information of moving objects in augmented reality, which is used to obtain information about moving objects in augmented reality games, the moving objects can be moving tanks, the method includes the following steps:

[0112] 1) The tank is placed on the background map, and a plurality of locations printed with identifiable location information are distributed on the background map. The location information is represented by an ordered combination of microscopic graphics representing binary characters, which includes the location location information on the map;

[0113] 2) Obtain the corresponding window image at the position of the tank through a camera set at the bottom of the tank and transmit the window image to the decoding chip (sonixSNC7312), wherein the camera is fixed at the middle of the symmetry axis of the tank bottom;

[0114] The decoding chip receives the window image transmitted by the camera, identifies and...

Embodiment 2

[0117] A system for rapidly and real-time obtaining information of moving objects in augmented reality is used in augmented reality games, and the moving objects involved in the augmented reality games are movable tanks. The system for obtaining moving object information includes a background map laid under the tank, a camera installed on the symmetrical axis of the bottom of the tank, a decoding chip and a Bluetooth signal transmitter, a Bluetooth signal receiver installed on the mobile phone (display terminal) and terminal processing device (terminal control module).

[0118] The background map is distributed with locations including location information set by microscopic printing technology, and the location information is an ordered combination of micrographics representing binary characters. The camera installed in the middle of the tank transmits the corresponding window image of the tank on the background map to the decoding chip, and the decoding chip identifies and e...

Abstract

The invention discloses a method and system for fast and real-time acquiring information of a moving object in augmented reality. The method includes the following steps: resting a moving object on a background map which is dotted with sites which are provided with site information; acquiring a window image corresponding to a position where the moving object is at, extracting and transmitting site information to a terminal control module which is in a display terminal; and the terminal control module processing the site information, and determining the information of the moving object on the background map through the site information. According to the invention, the method and the system for implementing the method associate real world and position information in augmented reality by acquiring site information, can fast, real-time and accurately acquire information of the moving object in the real world through augmented reality, and completes the positioning of the moving object in a display terminal.

Description

technical field [0001] The invention relates to the field of augmented reality, in particular to a method and system for rapidly and real-time obtaining information of moving objects in augmented reality. Background technique [0002] Augmented reality (Augmented Reality, AR) is a new technology developed on the basis of virtual reality (Virtual Reality, VR) technology. Virtual objects (graphics, images, texts, sounds, etc.) are correctly and reasonably superimposed on the real and real world that users can directly perceive, and the two are integrated to achieve the so-called "enhancement" effect. At present, video-based augmented reality systems generally require four steps to realize augmented reality: image acquisition of real scenes; real-time tracking and registration and positioning; virtual object rendering; virtual and real scene fusion display. This method first uses the camera to obtain the real scene video, uses the logo in the video stream to obtain the scene p...
