Abstract
The invention discloses a privacy protecting method in video monitoring of sensitive areas. Edge detection is carried out on video which is shot by a camera in a video monitoring area, and only an edge image instead of images which the camera shoots is transmitted in communication. Finally the edge image is displayed in various display equipment of monitoring terminal (mobiles, big screens, etc.), thereby achieving protection for privacy. The method can be applied to monitoring in significant sensitive places including homes, offices, hotels, etc. The method not only reduces the data bulk of communicative transmission, but also balances monitoring and privacy protecting simultaneously.
Description
Technical field
The invention belongs to the intelligent video field.For the edges only edge image of the secret protection that realizes the sensitizing range, reached the balance of secret protection and monitoring when having realized the minimizing of amount of communication data.
Background technology
Along with the video camera industry is changed on a large scale, the application of camera is popularized; At public safety, a large amount of cameras have all been used in the Smart Home monitoring.Artificial and to manage these video cameras constantly obviously impossible, in addition in commercial markets such as Smart Homes, traditional monitoring means that utilize the control room large-screen have been not suitable for general user's demand, and following terminal monitoring should be mobile devices such as mobile phone.Therefore need camera can judge intelligently that interested target occurs, and only send needed information, reduce cost of labor, save communication network bandwidth and secret protection simultaneously.
In field of video monitoring, most watch-dog all is the content that directly shows shot by camera at present.Have certain applications the picture that relates to private residence to be blocked and mosaic processing, but to the monitoring of sensitizing ranges such as being applied in the family, these methods are no longer valid all in providing of public safety field.
Summary of the invention
To the video monitoring that is applied to sensitizing ranges such as family, the present invention proposes a kind of brand-new privacy protection policy.Through input picture is carried out rim detection, output is edge image just.So not only reduce the data volume of communications, prevented hacker's intercepting user profile from the communication link, realized the balance of monitoring and secret protection simultaneously well.
Description of drawings
What Fig. 1 showed is camera head monitor zone and edge image thereof;
The appearance and the edge image thereof of moving-target (personnel) appears in Fig. 2 guarded region.
Embodiment
Video camera among the present invention sets up in the zone of required monitoring, and video camera is connected (perhaps processing module is integrated in the camera) through data wire with main control computer.Input picture is carried out rim detection, i.e. calculus of differences, such as the Sobel operator, wherein the intensity of edge detection operator is adjustable.Edge detection operator is the algorithms most in use in the image processing, and we have developed new function here, promptly comes monitoring is realized in the privacy sensitizing range with edge image.
Claims (4)
1. no matter adopt which kind of edge detection algorithm; As long as transmission is edge image, and the coded format of images no matter;
2. no matter on various terminal presentation facility, such as mobile phone, display, large-screen, panel computer etc., as long as final what show is edge image;
3. what no matter show is a pictures, or one group of moving-target picture (with the mode of video);
4. no matter whether comprise other equipment in the system.
All in the protection of this patent.
