[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in the case where video information from surveillance cameras installed in a cafeteria, a parking lot, a car park, and the like is distributed not only to a building disaster prevention management center but also to building employees and customers.
[0002]
[Prior art]
Conventionally, in a disaster prevention management center for buildings, surveillance cameras have been installed at major locations of buildings such as canteens, parking lots, and crowds to monitor illegal intruders and fire / damage. On the other hand, building employees do not know how busy the cafeteria is without going to the cafeteria. For example, if there is a duty to go to a post office or bank during lunchtime, the order of meals and duties is handled. There was a problem that it was not possible to plan in advance. In addition, when a purchaser or customer representative makes a meeting with a customer at the company's building, it is necessary to know when the customer will arrive without contact from the customer's extension phone or advance notice from the mobile phone. There was a problem to say. Here, the buildings include factories, office buildings, public facilities, and the like.
[0003]
Therefore, if video surveillance information for crime prevention and disaster prevention is distributed to building employees, purchasing personnel, and customer personnel, convenience for building users is enhanced. For example, a building employee can determine the order of meals and duties depending on how busy the cafeteria is. In addition, since purchasers and customer representatives can recognize from the video monitoring information that the customer has arrived at the car stop or doorway of the company's building, the purchaser or customer representative can determine the time until the customer arrives. You can concentrate on your work and respond quickly when customers arrive.
[0004]
[Problems to be solved by the invention]
However, if video surveillance information for crime prevention or disaster prevention is distributed as it is to employees in the building or in the vicinity of the building, purchasers, and customers, there is a problem in protecting portrait rights and privacy. For example, senior executives should only recognize that the customer to be served has arrived at the parking lot and should not be known to other employees or other companies.
[0005]
The present invention solves the above-mentioned problems, and video surveillance that can guarantee portrait rights and privacy protection when distributing video surveillance information for crime prevention and disaster prevention to employees, purchasers, and customers in charge of buildings. The purpose is to provide a system.
[0006]
[Means for Solving the Problems]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating an embodiment of the present invention. In the figure, surveillance cameras are installed in a cafeteria 1a, a parking lot 1b, and a vehicle entrance / exit 1c in or near a building, and take video information in real time. The site of the building is included in the vicinity of the building. The building video information distribution unit 10 uses the video information of the cafeteria 1a, the parking lot 1b, and the vehicle entrance / exit 1c photographed by the monitoring camera for the image display terminal of the image information user 4 for the restaurant user image information 3a. The image information 3b for the parking lot user and the image information 3c for the vehicle entrance / exit user are distributed. In addition, the building video information distribution unit 10 is also used for the image display terminal of the disaster prevention center / facility manager 2 for the dining room user image information 3a, the parking lot user image information 3b, the vehicle entrance / exit user image. The information 3c is distributed as video information captured by the monitoring camera.
[0011]
The portrait right protection unit 20 conceals a portrait right or privacy area in the video information and distributes it to the image display terminal of the image information user 4. For example, the person's face and clothes are colored in one color. Painted to recognize that the appearance is a person, but not to specify a specific person. The specific configuration of the image processing of the portrait right protection unit 20 uses a technique disclosed in, for example, Japanese Patent Laid-Open Nos. 9-275523 and 9-297836.
[0012]
The facility management right confirmation unit 30 distributes video information that has not been concealed to the image display terminal when it is confirmed that the image information user 4 who is viewing the image display terminal has the right authority. To do. For confirmation of the legitimate authority, a predetermined password may be used, and when authority is given to each person, the identity of the person may be authenticated by a fingerprint, a voiceprint, or an iris pattern. In addition, security can be ensured if the legitimate authority is given only to the vicinity of the scheduled arrival time of the planned visitor location by prior registration of the planned visitor and not given to other locations or outside the scheduled arrival time.
[0013]
Next, the operation of the apparatus configured as described above will be described. FIG. 2 is a distribution image for a general image display terminal showing the action of the portrait right protection unit, FIG. 2A is a background image, FIG. 2B is a current image captured by a surveillance camera, and FIG. Shows a distribution image with portrait rights protected. Here, the cafeteria is illustrated as a background image. In the dining room, the dining room facilities such as the entrance door 5a, the waiting area 5b, the dining room 5c, and the sample display shelf 5d serve as background images. At the time of meal, the user 5e queued in the waiting area 5b is shown, but the current video taken by the surveillance camera is shown in such a manner that the user can be identified, so the disaster prevention center / facility manager 2 Can be used. The portrait right protection unit 20 fills the difference area 5f between the background video and the current video with the same color and distributes it to the image display terminal of the image information user 4. This is because it is considered sufficient to be able to grasp the number of people in the queue as a video for a restaurant user.
[0014]
In addition to the user, the difference area 5f includes moving vehicles and objects, but such moving objects are also filled. The movement is mainly horizontal movement, and the movement in the depth direction is recognized as a change in the size of the subject in the screen. The difference area 5f requires an image area that is worthy of protection as a portrait right, and is not recognized as moving when the leaves of the tree are shaken by the wind. In addition, the moving speed is such that the pedestrian moves, and the right to protect portrait rights, and the vehicle that runs away is not protected. In the case of a three-dimensional image, it is preferable to extract only the depth information of the vehicle stopped at the vehicle entrance / exit 1c, and to remove the person at a place far away from the vehicle entrance / exit 1c from the subject of portrait right protection.
[0015]
Next, a case will be described in which distribution is performed for the image display terminal of the image information user 4 who is planning to visit. The visitor is distributed as image information 3c for the vehicle entrance / exit user taken by the surveillance camera installed at the vehicle entrance / exit 1c, but as a standby person, he wants video information that can determine who has arrived at the vehicle entrance / exit 1c. . Therefore, it is recognized by a password or prior visitor reservation that the facility management right confirmation unit 30 has a legitimate authority. Then, the video information captured by the surveillance camera that does not pass through the portrait right protection unit 20 is distributed from the building video information distribution unit 10 to the image display terminal that the standby person is viewing. Thereby, the stand-by can view the video information and confirm whether the customer has arrived at the vehicle entrance / exit 1c. Preferably, license plate information of a vehicle that is parked at the parking lot or the vehicle entrance / exit 1c may be distributed.
[0016]
In the above embodiment, the case where the difference area between the background image and the current image is painted with the same color as the action of the portrait right protection unit is shown. However, the present invention is not limited to this, and the standard image template for a person is used. The standard video template may be applied to a person in the difference area, and the video information may be provided as it is in the case of a dog or cat animal. In addition, when the difference area between the background video and the current video becomes large on the screen, it is preferable to use a mosaic pattern that does not infringe the portrait right.
[0017]
【The invention's effect】
As described above, according to the present invention, the portrait right protection unit is configured to conceal the area related to the portrait right or privacy in the video information, so that an unspecified number of viewers in or near the building can be viewed. Even if the video information is distributed to the person, the peace in the building or in the vicinity of the building is maintained, and the portrait right or privacy of the photographed person can be protected. When the facility management right confirmation unit confirms that the person viewing the image display terminal has the right authority, the video information that has not been concealed is distributed to the image display terminal. Therefore, natural video information is distributed to those who have a legitimate authority to protect the privacy of the photographed person, while improving convenience when the viewer is waiting.
