Description
Technical field
The present invention relates to field of intelligent control, particularly relate to a kind of intelligent domestic system.
Background technology
According to the record of Motion Picture Association of America, movie piracy makes film industry lose up to 60 every year
Hundred million dollars.Movie piracy has far-reaching influence to whole economic sectors, to such an extent as to he is in each state
Family or area are all identified a kind of criminal behavior.And a kind of main source of pirated film images exactly
Take on the sly, the most at the cinema or carry out film by mobile device in projection room and take on the sly.Although BBC
Report that major part movie piracy may be from industry internal staff and is supplied to the electricity in advance of movie critic
Shadow copy, but shooting is taken on the sly and is remained the online pirate important sources sold.Nearest tens
Year, the development of Internet bandwidth and point-to-point protocol all promotes the further circulation of pirated film.
In order to detect the digital multimedia video of uncommitted illegal propagation, digital watermark is by generally
Research and be widely used.In Making Movies or film ejection stage, can take to plant in film
Enter to make the method that human eye can't see " pattern " information.If these films are taken on the sly record by video camera,
This collection of illustrative plates embedded can be extracted and identify the source of piracy.
Some industry leaders are in order to identify and tracing pirate film, it is proposed that pass through Coded Anti-Piracy
(CAP) method, i.e. increases watermark in film.First Coded Anti-Piracy is designed by Kodak
, it is improved by Deluxe Laboratories subsequently.Philips it is also proposed in 2006
One mark system being named as CineFence.But, digital watermark is a kind of passive measure,
He can not eliminate and stop shooting to take on the sly.On the other hand, camera perturbation technique is intended to pass through heavy damage
Film visual quality eliminate shooting and take on the sly, to make these interference signals not interfere with movie theatre simultaneously
Spectators.
The most substantial amounts of camera interference method mainly make use of imaging sensor response ultrared former
Reason.In order to disturb mobile camera and generate light in the picture of shooting, infrared emitter is pacified
It is contained in cinema.Except extra cost price and the regular job expenses such as those emitters, this side
Case can be by enclosing suitable filter on camera lens.But this mode is easy to because of the person's of taking on the sly
Select and be avoided.
Accordingly, it would be desirable to a kind of new electronic anti-theft claps scheme, it is possible to auditorium image is carried out electronics and divides
Analysis, carries out electronic analysis to scene performance environment, and carries out the person's of taking on the sly judgement based on two kinds of analysis results,
It addition, the person of taking on the sly is reminded by the positional information being additionally based upon the person of taking on the sly, thus realize performance scene and steal
The oriented detection of bat person and orientation warning.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of intelligent domestic system, sight is set at the scene
Many seat image capture devices complete the extraction to auditorium image, introduce various image processing equipment and figure
As analytical equipment judges whether there is the suspicious person of taking on the sly in the image of auditorium, there is suspicious taking on the sly
In the case of person, extract the numbering at suspicious seat, the person of taking on the sly place, the most at the scene to environment
Parameter or current performance content detect in real time, with the information according to the suspicious person of taking on the sly and on-the-spot inspection
Survey result determine the person that really do not takes on the sly, it is even more important that establish a set of can be according to the person of taking on the sly position
It is oriented the mechanism of prompting, thus completely automatically realizes the detection of the electronic type to the person of taking on the sly and police
Accuse.

Detailed description of the invention
Below with reference to accompanying drawings the embodiment of the intelligent domestic system of the present invention is described in detail.
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 interval, 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
It is susceptible to let slip the person of taking on the sly of some corner location because of asthenia；Finally, arrange near spectators
The mode of staff brings discomfort to the spectators of normal viewing performance, have impact on them and appreciates performance
Mood.
As can be seen here, the artificial anti-mode taken on the sly has inborn deficiency, in order to overcome above-mentioned drawback,
Reducing the anti-operation cost taken on the sly, improve the anti-work efficiency taken on the sly, operator always searches for electronics
The anti-mode taken on the sly carries out on-site supervision, and the anti-two kinds of developing direction of having taken on the sly of electronics, one is spectators
Make an issue of on hand-held mobile terminal, automatically detect the behavior of taking on the sly when mobile terminal shoots, but this
The mode of kind is probably due to the selection of mobile terminal is avoided by the person of taking on the sly, and another kind is at the scene of taking on the sly
Disposing electronic jamming device, this mode can avoid evading of the person of taking on the sly.
The existing anti-electronic jamming device taken on the sly is that one infrared facility is placed in curtain or dance
The back side of platform, infrared facility sends the sightless infrared ray of human eye, if the person of taking on the sly is moving
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 intelligent domestic system, it is possible to by existing
In auditorium spectators behavioral value and by the parameter extraction of site environment is determined scene
Whether auditorium exists the person of taking on the sly, and can in time the position at the person of taking on the sly place be positioned, with
It is easy to take to orient warning measure accordingly, reminds the person of taking on the sly to abandon the behavior of taking on the sly.
