Problems solved by technology

[0004] At present, there are mainly two methods for counting the audience of TV advertisements in buildings. One is to use manual on-site observation and sampling, which is costly, low in accuracy and low in efficiency.
[0005] The other is to use infrared, electric field, microwave and other detection devices installed next to the TV advertising device in the building to detect whether someone passes or stays in front of the TV advertisement. This method can only roughly count the number of people, and cannot accurately determine whether people are watching. Advertising, used to count audiences with very low accuracy

Embodiment Construction

[0030] The embodiment of the present invention obtains the video information by picking up the image in front of the display on which the program is played, and the dynamic video information is composed of several frames of static images, and then performs face detection and face tracking analysis on each frame of the video information to obtain The detection and tracking information of each face is compared with the predetermined judgment criterion and the detection and tracking information, so as to obtain the audience information of the program.

[0031] The embodiments of the present invention are preferably suitable for broadcasting TV programs in relatively long and narrow locations, where the flow of people is large and concentrated. The typical application is the broadcasting of building advertisements, and of course it can also be applied to other advertising broadcasting scenarios.

[0032] Such as figure 1 As shown, the method for obtaining program audience informat...
