And, spectators have only to carry the various mobile terminal with camera can complete high-resolution image
Record or image taking, so, carry out piracy and take on the sly very easy, cause huge warp to relevant industry
Ji loss.
Piracy is taken on the sly and is typically occurred in cinema, theater, arenas, projection room or theatre, operation
Side is prevailing in order to avoid the behavior of taking on the sly, it will usually arrange special staff to be arranged in auditorium
Around, arrange one every fixed intervals, with the manner behavior of spectators near naked-eye observation, once send out
Existing spectators' hand-held mobile terminal carries out the recording of image or the shooting of photo, goes forward immediately to stop or adopt
Alert with hand-held infrared emission pen, thus interrupt the behavior of taking on the sly of spectators.
But, there is the drawback of inherence in this artificial anti-mode taken on the sly: first, if spectators' dishes served at a feast
Long-pending relatively big, then need to arrange for a lot of staff and carry out field monitor, it means that need substantial amounts of people
Work cost；Secondly, the mode inefficiency of staff's naked eyes scanning, and the mode of direct surveillance

Terminal or video camera shooting, then infrared ray is by the video camera imaging of the interference person of taking on the sly, causes the person of taking on the sly to obtain
The image obtained or lower picture quality, it is impossible to commercially sell and propagate on network, thus having
Effect safeguards copyright interest.
But, this mode needs to launch infrared ray always, and ultrared transmitting is large-scale,
Need all to launch infrared ray, relatively costly and poor feasibility from each position.Therefore on-the-spot electronics is prevented
The equipment of taking on the sly also needs to find other break through direction.
In order to overcome above-mentioned deficiency, the present invention has built a kind of based on graphical analysis remotely control and has put down
Platform, it is possible to by audience seat spectators behavioral value and by the parameter to site environment
Extract and determine whether audience seat exists the person of taking on the sly, and can position to the person of taking on the sly place in time
Put and position, in order to take to orient warning measure accordingly, remind the person of taking on the sly to abandon the behavior of taking on the sly.
