 In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clearly, the embodiments of the present invention will be further described in detail below. The illustrative embodiments of the invention and the description thereof are intended to be illustrative of the invention, and are not intended to limit the invention.

 1 is a flow chart showing a method of obtaining interactive information in an embodiment of the present invention. The method includes an input step (step S110), an information processing step (step S120), and a recognition retrieval step (step S130).

 In step S110, the mobile terminal starts the camera module, captures or records the picture image or video stream currently played by the television program, and uploads the image or video stream to the server.

 In step S120, the server detects and organizes the image or video stream to obtain graphic information. In step S130, the server side identifies according to the graphic information, obtains the television column information, and retrieves the interaction information corresponding to the television column information.

 The mobile terminal of the present invention includes a smart mobile terminal such as a mobile phone or a tablet computer, and has a camera module and is capable of performing basic shooting or recording operations. In the following embodiments, a method of obtaining interactive information is described in detail by taking a mobile phone as an example.

 Referring to Figure 2, there is illustrated a flow diagram of a particular method of obtaining interactive information in accordance with an embodiment of the present invention.

 In step 210, the mobile phone client is started, and the camera of the mobile phone is started, and a picture image or a video stream currently being played by the television program is captured or recorded.

During the broadcast of a TV program, if important information required by the user, such as: TV drama, real-time news, contact telephone number, and mailing address, appears, the user wants to record and save the information or interact with the TV program through the information. Mobile client, shooting directly via mobile phone containing this A television picture of the information, or a video stream containing the information. Among them, the camera of the mobile phone includes a front camera and/or a rear camera.

 In step 220, the mobile client saves the image captured by the mobile phone or the recorded video stream, and completes the collection of the information.

 At step 230, the mobile client uploads the image or video stream to the server.

 In step 240, the server detects, organizes, identifies, and retrieves the image or video stream to obtain interactive information corresponding to the television column information, and returns the obtained interactive information to the mobile phone client.

 The process of obtaining interactive information after the server side processes the image or video stream is specifically shown in FIG. 3 . FIG. 3 is a flow chart showing a process of obtaining interactive information by a server side according to an embodiment of the present invention.

 In step 310, the server receives image or video stream data uploaded by the mobile phone.

 At step 320, the server detects icon and text image information from the image or video.

 First, the server extracts key frames containing important information from the video stream, and detects the icons contained in the image or key frames according to a certain method (such as a color-based connected component method) or an algorithm (such as a texture-based segmentation algorithm). And the text area; Then, the text image of the text area is segmented from the background of the screen to obtain text image information.

 In step 330, the server side compares the icon and the text image information with the map library, and classifies and sorts the recognition result to obtain the graphic information.

 The server side compares the icon and text image information with the atlas and text set in the library. Among them, the atlas includes the logo of each TV station, and the text set includes but is not limited to: Chinese characters, letters, numbers, and the like. The server-side atlas and text set can also be downloaded and updated periodically from the network. By comparing the icon with the most similar pattern in the set, the graphic corresponding to the captured icon is determined. At the same time, the stroke feature of the text in the text image information can be compared with the text set in the map library to retrieve the most similar font. Finally, the results of the recognition are sorted and sorted to obtain graphic information.

 Step 340: Identify, according to the graphic information, the television column information corresponding to the graphic information on the server side, and retrieve the corresponding interactive information according to the television column information. This interactive information can be returned to the mobile client

The server side can save the logo of all current TV stations for comparison identification. By comparison The television station logo corresponding to the icon in the current graphic information is identified, and the accurate content of the television program corresponding to the logo is recognized by the text information in the graphic information, so that the accurate and useful television column information can be obtained, and then The TV column information retrieves the corresponding interactive information.

 If the corresponding TV column information is not recognized on the server side, the network can be searched, and the network includes a broadcast television network, an IP network, and the like.

 It should be noted that if the user only wants to obtain the TV station logo, the processing steps of obtaining the TV column information can be completed in the mobile terminal, and the mobile terminal saves the logo information of all the TV stations in advance to form an atlas. The mobile terminal detects the icon from the image or the video, and compares and recognizes the icon according to the icon and the atlas, wherein the atlas includes the logo of each television station. By comparing the icon with the most similar television station logo in the map set, the logo corresponding to the photographed icon is determined and the TV column information result is formed. Finally, the results are displayed to the user. The atlas saved by the mobile terminal can be downloaded and updated periodically via the network. The network includes a broadcast television network, an IP network, and the like.

 In step 250, the mobile client receives the interactive information returned by the server.

 After receiving the returned interactive information, the mobile phone can display interactive information through the display screen for the user to view, thereby selecting the required information. At this point, the user can process the interactive information.

 The mobile terminal provides a function for the user to process interactive information. Among them, the treatment methods include but are not limited to: participation in discussion, program broadcast, contact interaction, reply questionnaire, and the like. The user can complete the need by selecting different processing methods, which can be:

 Now choose to participate in the discussion, the following options are available for users to choose: related forums, related groups, etc., users can choose "related forums" or "related groups", enter the forum address related to TV programs to participate in the forum discussion or join the corresponding Group to come and express their opinions;

If you choose to broadcast the program today, you can choose the following options: View the story, program schedule, etc. The user can select "View Story" to get the story list link to view the TV story, and select "Program Schedule" to get the TV program. Play schedule Now choose to contact, you can choose the following options: Send SMS, call, save to address book, etc. Users can participate in live discussion through "Call" program hotline, or participate in voting by "send SMS", or pass "Save in Address Book" Save the program hotline or program mailbox address, for example: If the user is participating in the TV program voting activity, you can directly edit the name of the person or TV program you support and send the text message after extracting the hotline of the TV program. Yes;
