Abstract
The invention discloses a device and method for identifying video content based on video image fixed features. Viewing behavior information of a user can be obtained in a simple and rapid mode. According to the technical scheme, video signals output by a user play device or a television are connected into a surveying instrument, a video image is acquired, an image identification method is used for identifying fixed feature information in a video image and transmitting the information to a front-end server, and therefore the viewing behavior information of the user is obtained.
Description
Technical field
The present invention relates to image recognition, relate in particular to the apparatus and method of carrying out audience investigation by image recognition.
Background technology
In TV audience rating investigation field, to wonder that at present the user is seeing the two kinds of methods that have of what program main flow:
1: audio frequency comparison method:
With an investigating instrument equipment, the output of the audio frequency of user's playback equipment or television set is received on this equipment, gather the voice data that the user watches program, and pass through a characteristic in the audio frequency characteristics data extract algorithm extraction audio frequency, and these characteristics are transferred to system server terminal.Server end collects the audio frequency characteristics at that time of all channels that can see of this user by some equipment, also extracts the characteristic value of audio frequency.The audio frequency characteristics that user side is collected is compared in the audio frequency characteristics storehouse of all channels and is searched, thereby draws the current channel value of seeing of user.
The volume of transmitted data of the method is very big, and the expense of data bandwidth is very high; And server end builds check to the surveillance of all channels, the cost height, and the maintenance cost height, in case go wrong, all terminal image data are all scrapped, and can't provide the audience rating investigating report.In addition, do not have sound for programme content, perhaps several channels situation of relaying same video content simultaneously can't be identified, and accuracy is not high, and error ratio is bigger.
2: playback equipment software transplanting method:
In the software of playback equipment, add the software module that monitors the current broadcasting channel content of playback equipment, and the channel content information of collecting is passed back to system server terminal, thereby obtain the data of user watched behavior.
The advantage of this method is that transmitted data amount is low, and image data is accurate.But there is a born and shortcoming that be very difficult to overcome in this method, must cooperate with the developer of playback equipment exactly, and the developer who depends on playback equipment could realize that the cost of this part is very high, practical operation is very difficult, and project process self can't be controlled.
