Abstract
The method includes steps: starting up bar code recognition function in video data service; after video data service plays video service, the bar code recognition system (BCRS) picks up information ofeach image frame from call-back of video playing procedure, and sends it to BCRS to pick up and recognize information; when recognition is successful, corresponding interface is entered according toreturned bar code type; when terminal video service is started, bar code switch decides whether to start up bar code recognition function; when information of bar code is included in video frame and picked up, using type of bar code, the method changes flow to corresponding function without influence on normal function of video data service; when video data does not contain information of bar code, user cannot see any phenomena, and can recognize data frame in real time.
Description
Technical field
The present invention relates to a kind of terminal video traffic field, specifically, relate to a kind of method of in the terminal video traffic, obtaining bar code information.
Background technology
Bar code is bar, the null symbol of arranging by certain coding rule by a group, in order to the information of representing that certain character, numeral and symbol are formed; And bar code system is read the automatic recognition system of forming by bar code symbol design, making and scanning.Barcode technology because its information capacity is big, coding range is wide, have the secret characteristics such as antiforge function, the bar code reliability is higher, data debug ability is strong that reach, has been widely used in each field since inventing the nineties.In recent years, because of easy in the use, the quick characteristic of bar code, the someone adopts bar code to carry out commercial related application successively.Bar Code is widely used in the terminal at present, and the main method that adopts is used camera collection bar code picture exactly, discerns, thereby obtains bar code information.
Along with the arrival in 3G epoch, video traffic has become a part indispensable in the terminal applies, such as video telephone, Streaming Media and up-to-date a series of business such as terminal TV application.So, if include the bar code picture in some video data service, so, originally the method for merely carrying out information extraction with camera collection bar code picture can not satisfy terminal video traffic demand with rapid changepl. never-ending changes and improvements.
Summary of the invention
Technical problem solved by the invention provides a kind of method of obtaining bar code information in the terminal video traffic, has adopted barcode technology in video data service, can extract corresponding bar code information by this method.
Technical scheme is as follows:
Obtain the method for bar code information in the terminal video traffic, step comprises:
(1) in video data service, starts the bar code recognition function;
(2) after the video data service displaying video business, the bar-code identification system extracts the pictorial information of each frame in video playback readjustment, and sends to the bar-code identification system and carry out information extraction and identification;
(3) when discerning successfully, enter corresponding interface according to the barcode types of returning.
Further, in the step (1), include the starting switch of bar-code identification in the described video data service, the user all can start or close the bar-code identification function after video data service begins preceding or begins.
Further, in the step (2), described bar-code identification system provides interface by bar code supplier.
Further, in the step (2), information extraction that described bar-code identification system carries out and identification and video data service are parallel, do not influence mutually.
Further, in the step (3),, illustrate not comprise the bar code image content in this two field picture or bar code information does not wherein meet the bar code standard if recognition function returns recognition failures, not break of video data service this moment, and directly carry out the picture extraction and the identification of next frame.
Further, in the step (3), described barcode types comprises SMS type bar code or email type bar code.
The present invention has following advantage:
1, when starting the terminal video traffic, can determine whether starting the bar code recognition function according to the bar code control switch.
2, when including bar code information in the frame of video, can forward function corresponding to according to barcode types after extracting bar code information, and not influence the normal function of video data service.
When 3, not containing bar code information in the video data, the user can't see any phenomenon, but the Real time identification Frame.
Description of drawings
Fig. 1 is the present invention's general bar code information extracting method flow chart in the terminal video traffic.
Embodiment
In order to satisfy the demand that bar code is used in terminal video traffic widely, the present invention proposes a kind of method of obtaining bar code information in the terminal video traffic, if adopted barcode technology in some video data service, as long as include the bar code picture in the video data service, can extract frame of video and in real time it be carried out information extraction, certain bar code information in identifying certain frame of video, the single bar code information is extracted successfully, carries out the bar code information of next frame then as requested and extracts.
With reference to the accompanying drawings, the preferred embodiments of the present invention are described in detail.
Step S101: the user starts the bar code recognition function in video data service.
The starting switch that includes bar-code identification in this audio data business, the user all can start or close the bar-code identification function after video data service begins preceding or begun.
Step S102: video data service begins according to after certain frame rate displaying video business, recognition system begins to extract the pictorial information of each frame in video playback readjustment, and this frame picture is sent to bar-code identification system (providing interface by bar code supplier usually) according to certain form carries out information extraction.
Step S103: the decoding functions that the information that pictorial information and other built-in functions are needed (such as the terminal IMEI number etc.) is passed to the decoding storehouse to be provided is resolved and is discerned.Herein, pictorial information can be the image file of RAW form.
The information extraction of bar-code identification system and video data service are parallel, do not influence mutually.Video data service continues playing audio-video, continues the backstage and plays, just display video not.
Step S104: judge whether identification is successful.
If discern successfully execution in step S105; Otherwise, execution in step S106.
Step S105:, then enter corresponding interface according to the barcode types of returning if discern successfully.
If barcode types is a SMS type bar code, then enter into short message module; If barcode types is an email type bar code, then enter into the email module ....At this moment, can also determine whether to stop current video data service according to demand, temporary transient frame of display video is not just preserved or after transmission etc. disposes, is continued to get back to step S106 again up to bar code content.
Step S106: if recognition failures illustrates not comprise the bar code image content in this two field picture that perhaps bar code information does not wherein meet the bar code standard, not break of video data service this moment, and directly carry out the picture extraction and the identification of next frame, then, execution in step S103, so repeatedly.
