Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, the embodiments of the present invention exemplified below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below.

The embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

1 is a view for explaining the state of the tracking of the pedestrian and the irradiation of laser light according to the present invention, CCTV modules (100,100-1,100-2) for photographing pedestrians in alleys or in rare places are installed at regular intervals. , These CCTV modules (100,100-1,100-2) may be a rotating type that can be changed by rotating the shooting direction or a fixed type that can only shoot in a preset shooting direction.

In FIG. 1, as an example, a fixed CCTV module (100, 100-1, 100-2) is illustrated, and is installed to enable shooting in one direction, so that a pedestrian moving from right to left or moving from left to right can be continuously photographed. There will be.

For example, in the case of an alleyway, CCTV modules (100,100-1,100-2) are installed at regular intervals from the beginning to the end of the alleyway, and a plurality of CCTV modules (100,100-1,100-2) cover the entire area in the longitudinal direction of the alleyway. By dividing and photographing, it is possible to prevent blind spots from occurring.

In addition, the CCTV module (100,100-1,100-2) can be configured to track the user on a 1: 1 basis by pan motion, tilting motion, and zoom-in motion, but instead of tracking only one pedestrian, the entire street is always taken. It should be installed in a fixed type because it must be.

When the pedestrian 200 is located within the shooting range of the CCTV modules 100, 100-1, and 100-2 and acts for a tracking request, the first CCTV module 100 photographing it recognizes the behavior of the pedestrian 200 To determine whether to request tracking.

That is, in the CCTV module 100, the pedestrian's action information for tracking request is stored in advance, so that when the pedestrian forms a circle with his right hand sideways or both hands overhead, it is recognized as an action for tracking request. do.

Subsequently, even if the pedestrian 200 does not act for tracking, the CCTV module 100 recognizes the shape and location of the pedestrian in the screen to be photographed and generates pedestrian recognition information, thereby generating the pedestrian recognition information. Laser light (L1, L2) is irradiated to the surroundings.

In addition, when the pedestrian 200 moves, the moving path is tracked by the pedestrian recognition information to irradiate laser light L1, L2 to the surroundings. At this time, from the fixed CCTV modules 100, 100-1, 100-2, Since the location and range of the captured image is fixed and the pedestrian 200 moves within the fixed screen, the movement of the pedestrian 200 is recognized and the CCTV module 100, 100-1, 100-2 ) Is irradiated with laser light (L1, L2) around the pedestrian 200 by the laser pointer provided.

Of course, when the pedestrian 200 moves to the location of the second CCTV module 100-1, the second CCTV module 100-1 receives Rola communication and IoT communication from the first CCTV module 100. It is possible to irradiate the laser light (L1, L2) to the surroundings while being continuously tracked by the pedestrian received by the back.

Likewise, even when the pedestrian 200 moves to the shooting range of the third CCTV module 100-2, tracking and irradiation of laser lights L1 and L2 are possible as described above.

In addition, since the position of the laser lights L1 and L2 can be recognized from the image photographed by the CCTV modules 100, 100-1.100-2, the laser lights L1 and L2 can follow the position of the pedestrian 200. To control the laser pointer.

Therefore, by recognizing the pedestrians 200 entering the alleys and irradiating laser lights L1 and L2 around the moving pedestrians 200, the pedestrians 200 are tracked by CCTV to prevent crime. It is possible.

Each CCTV module (100,100-1,100-2) is configured as shown in FIG. 2, but the camera 110 is basically positioned to face an area that it can shoot as shown in FIG. 1, and the camera 110 The image taken from is input to the image recognition unit 120 to recognize whether there is an action for a tracking request from the pedestrian 200.

As the image recognition technology by the image recognition unit 120, a general publicly known technique can be used, for example, real-time using Kalman filter and clustering algorithm based on JP continuous method No. 10-2015-0002040. Pedestrian Recognition and Tracking Method), Registered Patent No. 10-1761604 (Multiple Pedestrian Recognition, Tracking System and Control Method), Registered Patent No. 10-1588648 (Pedestrian Detection and Tracking Method for Intelligent Video Surveillance), etc. The image recognition and pedestrian tracking methods will be available.

When it is recognized that there is a tracking request from a pedestrian, the controller 130 provides pedestrian recognition information consisting of the tracking request recognition information and the shape information and location information of the pedestrian, and accordingly, the controller 130 as shown in FIG. 1. The driving unit 140 is controlled by an irradiation control command so that the laser lights L1 and L2 may be irradiated to the periphery of the pedestrian 200, but is recognized and provided by the image recognition unit 120. The laser point 150 is controlled so that one or a plurality of laser lights L1 and L2 may be irradiated around the pedestrian 200 by location information.

That is, the laser point 150 is provided with one or a plurality of, or can be driven by a pan and tilt, to irradiate the laser light (L1, L2) around the pedestrian 200, and also by the camera 110 The captured image is transmitted to a remote location through the communication unit 160 so that the manager can quickly grasp the emergency situation.

Meanwhile, the communication unit 160 may be configured as a Rola or IoT communication module, and transmits pedestrian recognition information to neighboring CCTV modules (100, 100-1, 100-2) to track pedestrians in connection with surrounding CCTV modules and move as well. The laser light is irradiated around the pedestrian.

That is, the controller of the neighboring CCTV module receives the pedestrian recognition information through the communication unit and then, if the corresponding pedestrian is recognized from the image taken through his camera, drives a laser point to irradiate the laser light to the surroundings of the pedestrian.

Therefore, even if the pedestrian is out of the shooting range of one CCTV module, it is possible to continuously track and irradiate laser light by the neighboring CCTV module.

In addition, when the pedestrian 200 exits the alley or is in a safe state, it is desirable to end tracking, for example, an action for ending tracking from the pedestrian 200, for example, lifting one hand over the head or extending both hands to the side. In the case of, the image recognition unit 120 recognizes this and stops the driving of the laser pointer 150 by providing the recognition information for termination of tracking to the controller 130.

However, if the pedestrian disappears from the screen and is not recognized without an action for termination of tracking, it may be a crime or other urgent situation, so the image recognition unit 120 provides the pedestrian's unrecognized information to the controller 130, Because of this, the controller 130 transmits a signal for an emergency through a communication unit 160 to a remote location, for example, a police station, a central control station, or the like.

Since the specific parts of the present invention have been described in detail above, for those skilled in the art, this specific technology is only a preferred embodiment, and it is obvious that the scope of the present invention is not limited thereby. something to do.

Accordingly, the substantial scope of the present invention will be defined by the appended claims and their equivalents.
