3) user clicks any viewing area, and handheld device then identifies the corresponding visible light label substance in the viewing area.
Handheld device identifies the content of each visual optical label, and generates list according to recognition result, and by the list display
Into the display area of handheld device.
List is generated according to the recognition sequence of each visual optical label according to the recognition result of each visual optical label.
The outdoor scene that visual optical label is inserted into the visual optical label position is shone by way of superposition in step 2)
In piece.
Each viewing area is distinguished by adjusting the background color of each viewing area.
By the way that each viewing area is distinguished in the different text of viewing area internal labeling.
Step 1) user obtains all visual optical labels in camera identification range by the camera in handheld device
Concrete operations are as follows: the focal length of camera in adjustment handheld device makes camera in handheld device obtain camera identification model
Enclose interior all visual optical labels.
The invention has the following advantages:
The method for quickly identifying of multiple optical labels of the present invention shows all visual optical labels when specific operation
It is basic point by the viewing area of handheld device into the display area of handheld device, then using the regional center position of each visual optical label
Regional partition is several viewing areas, while being distinguished to each viewing area, so that each visual optical label be avoided to cause confusion, then will
Visual optical label and its outdoor scene photo of position are inserted into the corresponding viewing area of the visual optical label, are looked into convenient for user
It askes, user clicks interested viewing area, and handheld device identifies the corresponding optical label content in the viewing area, to realize multiple
The quick identification of optical label, it is easy to operate, the unrecognized problem of multiple optical labels is existed simultaneously in effective solution screen.
Detailed description of the invention
Fig. 1 is the division result figure of each viewing area in embodiment one；
Fig. 2 is the division result figure of each viewing area in embodiment two.
Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing:
