Plus it is convenient and quick.For example, possessing the entertainment selection based on augmented reality in large-scale recreation ground, augmented reality glasses are according to trip
Some specific positions and some real world objects are recognized in happy field, new image is superimposed in the user visual field.And current skill
Art needs augmented reality glasses to call camera, shoots object in the visual field, and according to the difference of tupe, in local runtime figure
As recognizer is processed the information for shooting acquisition or uploads to high in the clouds by the information for obtaining is shot, processed from high in the clouds
Returning result afterwards.The former is by considerable drain local cpu resource and electricity, and the latter will expend very big bandwidth.Identification image into
The image of superposition is needed generally to be also required to be downloaded from high in the clouds after work(, this part work can equally expend very big bandwidth.Use
The transmission method that the present invention is provided, only need to add communication transmitting device by illuminating LED, and one is added in glasses receiving terminal
Communication receipt module, under same scene, augmented reality glasses of the present invention can directly receive corresponding LED in scene
Signal, i.e., be presently in position strong correlation, and take the network bandwidth without uploading to download, directly receive what LED transmission came
Information is simultaneously superimposed upon the display interface of augmented reality glasses, greatly facilitates recreation ground and uses.
Again for example, the show window in shop is often Chang Liang, and based on energy-conservation and more preferable lighting effect, need a large amount of
Using LED.If adding the communication launcher in the LED of roadside shopper window, pedestrian when going window-shopping, except can
To enjoy outside the purpose for pointing the direction and navigating that augmented reality glasses band comes, cupboard can also be received by communication receipt module
The relevant information of commodity in window, and relevant information is directly superimposed upon the display interface of augmented reality glasses, such as advertisement video, business
Product place of production etc., to reach more preferable purchase experiences.
In the present embodiment, between augmented reality device and communication transmitting device, between augmented reality device and Cloud Server,
And the principle between communication transmitting device and remote server, the various embodiments described above are refer to, will not be repeated here.
The preferred embodiments of the present invention are these are only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
