Description

{Multifunction security camera}

The present invention relates to a multifunctional surveillance camera, and more particularly, to a multifunction surveillance camera, which is mounted on a vehicle such as a vehicle and automatically recognizes and analyzes other vehicles while moving, and recognizes the number by auto zoom To a multifunction surveillance camera capable of recording and transmitting an image of a number-recognized vehicle by wireless communication with a remote server.

In the 10-1241083 (subject-adaptive infrared ray floodlighting camera), the exposure of the surveillance camera is minimized by projecting the projection in the direction of the front subject while the searchlight is driven only when there is a subject in front, As the zoom-in operation of the zoom camera and the direction of the light source projection of the LED motor search light are adjusted according to the distance of the subject, the recognition of the forward object can be performed accurately and precisely, thereby monitoring the vulnerable area outside the military unit It proposes an effective surveillance camera to monitor work sites or complex areas of national important facilities or large factories.

However, in the surveillance camera according to the related art, only when there is a subject, the searchlight is driven and the exposure of the surveillance camera is minimized by performing a zooming operation on the camera in accordance with the distance from the subject. However, There is a problem in that exposure of the surveillance camera must be accompanied from the initial driving of the searchlight by projecting the light source with one brightness.

Further, the prior art has a disadvantage in that it can not specify and monitor only a target object to be monitored, because it has only a function of a surveillance camera that captures and recognizes a subject.

Accordingly, in order to solve the above problems, the present invention aims at minimizing the exposure of the surveillance camera by irradiating the searchlight with a low amount of light at the initial stage when capturing and recognizing a subject and increasing the amount of light only when recognition is impossible due to low light amount The present invention also provides a multifunctional surveillance camera that transmits an image captured by a server at a remote site to determine whether the surveillance target is a target, and then determines whether or not to continuously capture the surveillance image.

In addition, the present invention provides a surveillance camera having excellent field adaptability by rotating the camera at different angles of rotation according to the speed, position value, and road conditions of the moving means when mounted on a transportation means.

In order to achieve the above object, the present invention has a searchlight capable of irradiating a multi-stage light amount, a camera capable of zooming in and photographing infrared rays, a communication unit for communicating with a remote server, and a driving unit for rotating and tilting the camera.

According to the present invention, it is possible to minimize the exposure of the surveillance camera by the searchlight that irradiates the light amount in multiple stages, and to increase the efficiency of surveillance by intensively photographing only the target surveillance target. In addition, So that the efficiency of surveillance can be improved.

The present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating an external structure of a surveillance camera according to an embodiment of the present invention. Referring to FIG. 1, a camera 110 capable of zooming in and taking infrared rays, an infrared lamp 120, and a searchlight 130 are arranged in a row do.

The camera 110 employs a 5 to 50 mm high performance lens, the search light 130 is composed of LEDfh, and is composed of three 10 W LEDs and has a light quantity of 93,000 cd.

The rotation unit 140 rotates the module composed of the camera 110, the infrared lamp 120, and the searchlight 130, and a tilting unit 150 for tilting the camera in the vertical direction.

At this time, the rotation unit 140 can be rotated by 360 °, and the tilting unit 150 can be tilted by 37 ° in the vertical direction.

The control unit 160 controls the camera 110, the infrared lamp 120, the searchlight 130, the rotation unit 140, and the tilting unit 150. In the present invention, And a monitoring object is a vehicle.

3, the control unit 160 analyzes the image captured by the camera 110 to detect a vehicle type when the vehicle exists in front of the vehicle. Recognizes and zooms in on the license plate part.

At this time, when the external light quantity is sufficient and the brightness of the controller 160 is sufficient to recognize the image, the search light 130 is not driven. Otherwise, the search light 130 is driven, And then recognizes the image again.

However, when the image is not recognized, the search light 130 is driven to have the maximum amount of light in the second order.

On the other hand, when the search light 130 is not used by the user in a state in which the light amount is not sufficient, the infrared lamp 120 is driven to photograph the infrared image by the camera 110.

When the image is acquired, the controller 160 recognizes the type of the vehicle. The vehicle type is recognized based on the external appearance and the characteristic point of the vehicle, and a known technology can be used for the recognition of the type of the vehicle.

For example, the frame ratios of the vehicle's top, bottom, left, right, and rear sides are calculated and compared with predetermined comparison data to know the type of the vehicle, and the distance can be confirmed by the size of the vehicle.

When the identification and the distance of the vehicle type are confirmed, the position of the license plate is fixed. Therefore, the control unit 160 drives the rotation unit 150 and the tilting unit 150, zooms the camera 110 by distance data, And then the vehicle number is recognized.

The recognized vehicle type, the vehicle number, and the position data confirmed by the GPS unit 180 are transmitted to the remote integration server through the wireless communication unit 170.

The integration server at the remote site confirms whether the vehicle number transmitted through the pick-up vehicle database is a number of vehicles.

However, if it is confirmed to be a wander vehicle, the transmitted location data is transmitted through the integrated CMS to transmit alert, image, and location information to the police box / earth station and the on-site support vehicle .

At the same time, the surveillance camera 100 of the present invention reads data from the witness vehicle database and transmits the data to the witness vehicle so that immediate action can be taken in the field.

In the present invention, the controller 160 controls the rotation unit 140 and the tilting unit 150 according to the information acquired by the GPS unit 180. The controller 160 controls the rotation unit 140 and the tilting unit 150 according to the position value, The rotation angle and the rotation speed of the camera are controlled.

For example, according to the GPS position information, the rotation unit 140 is controlled so that the present invention can rotate at 360 ° at a high speed in the busy area. In the highway, rotation is limited to 90 ° to 130 ° When the running speed is slow, the rotation speed of the rotation unit 140 can be driven slowly in accordance with the speed of the rotation.
