Description
Technical field
The invention belongs to the technical fields of guideboard guiding, and in particular to a kind of interaction display side that AR is combined with guideboard
Method.
Background technique
With the deep development of economic globalization and world economic integration, when tourist industry enters fast-developing gold
Generation.People's out on tours is increasingly frequent, and travels on the way in people, and the demand to navigation type APP is also higher and higher.
Guideboard plays the effects of mark, guiding, since increasingly prosperity, the guideboard of city bus have evolved into city one
A indispensable important component.However the single guidance information of traditional guideboard makes the effect of guideboard lower and lower, and
Cost is high again for dynamic electronic road board.
Augmented reality (Augmented Reality, AR) is a kind of position for calculating camera image in real time
And angle and plus respective image, video, 3D model technology, the target of this technology is that virtual world is covered on the screen
Real world is simultaneously interacted.It is a kind of by " seamless " the integrated new technology of real world information and virtual world information, is
Script is difficult experience in the certain time spatial dimension of real world entity information (visual information, sound, taste,
Tactile etc.), it by science and technology such as computers, is superimposed again after analog simulation, by virtual Information application to real world, really
Environment and virtual object have been added to the same picture in real time or space exists simultaneously and by human perception, to reach super
More real sensory experience.
Summary of the invention
It is an object of the invention to combine emerging AR technology with the guideboard being seen everywhere, a kind of AR and guideboard are provided
The interaction display method combined, to solve the problems, such as traditional guideboard single-function.
To realize the above-mentioned technical purpose, the technical scheme adopted by the invention is as follows:
A kind of interaction display method that AR is combined with guideboard, comprising the following steps:
Step 1: including the characteristic of guideboard, establishes server-side guideboard property data base；
Step 2: mobile terminal was included the guideboard of characteristic using the scanning of AR software camera, identified the spy of the guideboard
Levy data；
Step 3: server-side is matched according to the characteristic of guideboard with the guideboard data of property data base, after the completion of matching
Guideboard information is returned to mobile terminal；
Step 4: the guideboard information superposition of server passback shows that on the guideboard image that mobile terminal is scanned, user is as needed
It clicks and obtains different guideboard information, to realize interaction display.
To optimize above-mentioned technical proposal, the concrete measure taken further include:
In above-mentioned step one, server-side guideboard property data base method for building up is as follows:
The guideboard big for discrimination shoots outdoor scene guideboard on the spot, is cut and disassembled analysis to the guideboard image of shooting, raw
At guideboard characteristic, internal identification id is generated for the characteristic；
The guideboard small for discrimination generates internal identification two dimensional code using two dimensional code Core Generator, is fabricated to paster, is attached to road
On board, internal identification id is constituted；The internal identification id and guideboard characteristic constitute guideboard property data base.
To the guideboard image of shooting according to the ratio of length and width 2:1, core of mode of the pixel not less than 480pixel to guideboard
Heart road name region is cut.
The characteristic of guideboard is generated using AR frame (ARKit, Vuforia) to the picture cut, the guideboard
Characteristic includes the color of image, texture, shape and spatial relationship information.
In above-mentioned step three, matching process are as follows: by computer vision algorithms make, obtain one group of color, texture, shape and
Spatial relation characteristics, the characteristic point that will acquire are matched with prefabricated guideboard property data base, and the matching process is
Characteristic point head-on collision matching, if two characteristic point similarities reach 80% or more, the guideboard image and guideboard feature database of mobile terminal scanning
Images match success.
In above-mentioned step three, guideboard information includes destination guidance arrow, promotional videos, publicity pictures, distance, time
And prompting message.
In above-mentioned step four, interaction display includes AR navigation, destination publicity and intelligent recommendation.
The invention has the following advantages:
1) the method for the present invention can allow user when travelling outdoors, travelling, and be obtained by the guideboard in scanning roadside conveniently by AR skill
The outdoor scene and the precision navigation Service that combines of virtual image that art is realized, in addition the ambient services of APP, sight spot preview, common
The functions such as navigation, bring novel sensory experience while providing tourist site valuable information for user, reach improvement with this and use
The purpose of family travelling experience.
2) function is shown by AR interest, in theme scape after scanning guideboard on some famous themes travelling ground
Area combines AR technology with scenic spot theme, and AR personalization is presented and shows, allows tourist to participate in scenic spot in AR outdoor scene personalized mutually
Rotating ring section, for user take novel experience while, also bring brand effect for major tourist attraction, improve scenic spot brand and know
Name degree.
3) present invention is not limited only to tourist site, and equally applicable large size square, all kinds of streets need to only scan roadside guideboard
Interesting precision navigation Service or manual search destination are enjoyed, AR navigation feature can be opened, can be presented after scanning
Accurately airmanship, the interesting AR picture of intention create a Tourism Ecological using AR technology, undoubtedly will receive users
Welcome and like.
