Show that region segmentation is some viewing areas, wherein, a visual optical label corresponds to a viewing area；
2) each viewing area is made a distinction, and the outdoor scene photo of visual optical label position is inserted into this visual cursor
Sign in corresponding viewing area, visual optical label is inserted in the outdoor scene photo of this visual optical label position simultaneously；
3) user clicks on arbitrary viewing area, and handheld device then identifies this viewing area corresponding visible light label substance.
Handheld device identifies the content of each visual optical label, and generates list according to recognition result, and by this list display
To in the viewing area of handheld device.
Recognition result according to each visual optical label generates list according to the recognition sequence of each visual optical label.
Step 2) in by superposition by way of by visual optical label be inserted into this visual optical label position outdoor scene shine
In piece.
By adjusting the background color of each viewing area, each viewing area is made a distinction.
By the word different in viewing area internal labeling, each viewing area is made a distinction.
Step 1) user pass through handheld device on photographic head obtain photographic head identification range in all visual optical label
Concrete operations be：The focal length of photographic head in adjustment handheld device, makes the photographic head in handheld device obtain photographic head identification model
All visual optical label in enclosing.
The invention has the advantages that：
The method for quickly identifying of multiple optical label of the present invention, in concrete operations, all visual optical labels is shown
To in the viewing area of handheld device, then with the regional center position of each visual optical label for basic point by the viewing area of handheld device
Regional partition is some viewing areas, each viewing area is made a distinction simultaneously, thus avoiding each visual optical label to cause confusion, then will
The outdoor scene photo of visual optical label and its position is inserted in the corresponding viewing area of this visual optical label, is easy to user and looks into
Ask, user clicks on viewing area interested, and handheld device identifies this viewing area corresponding optical label content, thus realizing multiple
The quick identification of optical label, simple to operate, effectively solve the problems, such as in screen, there are multiple optical label None- identifieds simultaneously.
Brief description
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.
