Method for rapidly and timely acquiring moving object information in augmented reality

Abstract

The invention discloses a method for rapidly and timely acquiring moving object information in augmented reality. The method comprises the steps of setting a plurality of sites which includes site information on a background map, and placing a moving object on the background map; acquiring a corresponding window image at the position of the moving object, extracting the site information and then transmitting the site information to a terminal control module on a display terminal; and processing the site information by the terminal control module, and determining the information of the moving object on the background map through the site information. The site information includes positional information of the sites, the real world and the positional information in the augmented reality are associated through the site information, the information of the moving object in the real world can be acquired rapidly, timely and exactly, and the locating on the display terminal is completed.

Description

technical field [0001] The invention relates to the field of augmented reality, in particular to a method 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 position inf...

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
