A TV program recognition method and system based on image recognition

Abstract

The invention discloses a television program identification method based on image identification and a system thereof. The method comprises the steps that S1, a video acquisition card acquires live video images of all television channels, extracts video image characteristic values of all the television channels and transmits the video image characteristic values to an image processing server; S2, the image processing server establishes and updates a video image characteristic index table of all the television channels in real time; S3, a mobile terminal shoots the screen frame of the current television channel, extracts the video image characteristic values of the screen frame and transmits an image identification request and the video image characteristic values to the image processing server; S4, the image processing server compares the video image characteristic values of the current television channel and the video image characteristic values in the real-time video image characteristic index table, and confirms the channel ID of the current television channel; and S5, the mobile terminal confirms the program to which the current live video is attributed according to the channel ID. Image identification accuracy and efficiency can be enhanced by the method so that anti-interference capability is high.

Problems solved by technology

[0005] The existing TV program image recognition technology generally extracts the TV station logo and channel name in the TV screen to identify and determine the TV program that the user is participating in, but this method is difficult to achieve good results in practical application. Effect

According to experiments, usually the distance between the user and the TV is 2-3 meters or more. Under such distance conditions, the TV station logo and channel name in the TV screen shot by the mobile phone will be very small, and the shooting light will be poor, and the deviation caused by the shooting angle of view It will also cause the shooting picture to be unclear. The images collected in these situations are not suitable for comparison and analysis with the channel data in the server background, which will lead to inaccurate recognition results, and often need to be repeatedly shot for recognition.
