Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of method of projection, is applied in mobile hotspot device, referring to Fig.1, in one embodiment, should
The method of projection includes:
Step S101 acquires image information after opening acquired projections mode；
In the present embodiment, mobile hotspot device is also referred to as uFI equipment.The acquired projections mode of mobile hotspot device includes text
This acquired projections mode and Image Acquisition projection mode.In the specific implementation process, mobile hotspot device opens acquired projections mould
After formula, then real-time image acquisition information is handled according to acquired image information is further.
In the present embodiment, text collection projection mode is supported to identify the text in acquired image information by recognizer
This information, and Projection Display is carried out with text mode；And Image Acquisition projection mode directly carries out acquired image information
Projection Display.
In the present embodiment, after mobile hotspot device acquires image information, it is introduced into text collection projection mode, if institute
There is no text information in the image information of acquisition, then enters Image Acquisition projection mode.
Whether step S102, detecting in acquired image information includes text information；
In the present embodiment, can be judged by Preprocessing Technique etc. in acquired image information whether include
Text information enters text collection projection mode, and further right if in acquired image information including text information
The text information for including in image information is identified.
Step S103 identifies the text information and carries out Projection Display if including text information in described image information；
In the present embodiment, when judging in acquired image information comprising text information, as shown in the pictorial information
When what is shown is a document information containing text, the text information in pictorial information is identified.
In the present embodiment, identification text information includes by local identification or cloud identification or local identification and cloud
Identify in conjunction with mode identify text information.
In the present embodiment, can by being pre-processed, being analyzed to the text information in image information, Character segmentation,
The technologies such as feature extraction, character recognition and later period correction are identified, or can also pass through existing recognizer, such as optics
Character recognition (Optical Character Recognition, OCR) technology etc. identifies it.
Wherein, if in acquired image information including text information, it is to pass through that mobile hotspot device, which prompts the user with,
Local identification or cloud are known otherwise to identify text information, if user does not select to know otherwise, using silent
It is identified for the identification method recognized.The identification method of default is first to carry out local identification to text information, i.e., by built in the machine
Recognizer identified, if local identification fails to identify, using cloud is wirelessly connected, send it to cloud
Further identified.
The present embodiment can be improved the speed of identification by local knowledge otherwise, so as to which it is aobvious rapidly to carry out projection
Show；The accuracy rate that can also improve text information identification significantly otherwise is known by cloud.
In addition, in general, if local identification can identify text information, being stored to local, such as
Fruit carries out cloud identification, then will identify that the text information storage come is beyond the clouds or local.
In the present embodiment, it can say that the text information identified carries out Projection Display according to the setting of user.Such as user
The size and color that text can be set are arranged the indicating template etc. of Projection Display, the effect of display are promoted with this.
Described image information is carried out Projection Display if not including text information in described image information by step S104.
In the present embodiment, if it is determined that not including text information in acquired image information, then by figure collected
As information directly carries out Projection Display.
Therefore, the mobile hotspot device of the present embodiment can be with real time scan to obtain image information, if the image information
In include text information, then local identification is carried out to text information or cloud identifies, will identify that the text information that comes into
Row Projection Display does not need the auxiliary of other equipment, and especially under working environment, the Projection Display of text information is quick and square
Just；And if not including text information in image information, directly visual information projection can be shown, make mobile hotspot device
Has real time scan projecting function.
