Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a security camera system for a vehicle,

The present invention relates to a vehicle security camera system installed on a main road or in a location where security is required to recognize a vehicle and to take multiple photographs.

Various types of crime prevention and security systems are used. For example, a certain area (specifically, a road area) is sensed to detect the presence of a vehicle, and according to the detection result, A crime prevention CCTV system is used as the crime prevention system.

A typical vehicle security CCTV system is implemented by installing photographing cameras for each of the lanes and installing sensors such as a loop sensor, a laser sensor or a video motion sensor for detecting the vehicle.

When a vehicle traveling through the corresponding lane is detected according to an operation of a sensor for detecting the vehicle, a camera arranged to photograph a corresponding lane on the basis of the detection result of the sensor is operated to photograph the vehicle And the image information thus photographed is transmitted to a control center of an institution such as a security center.

In recent years, due to the increasing number of crimes using vehicles, more and more evidence data is required. In order to satisfy this demand, the technology of vehicle security CCTV system is also developing.

On the other hand, in the case of the conventional CCTV security system in the related art, since the camera is fixedly installed, only the unidirectional photographing is possible, so that the front side or the diagonal upper side of the vehicle is photographed by the installation position of the camera.

However, since the shooting range of the cargo area of the vehicle, which is one of the main purpose of the crime prevention CCTV, is so small that the shooting of the loading cargo is not easy, not only the overcontrolling but also the captured image data could not be utilized for the verification of theft cargo. There is a problem that it is difficult to discriminate whether the front and rear license plates are forged or not, and thus the recent crime prevention requirement described above can not be satisfied.

In order to solve such a problem, a 360 degree omnidirectional camera is disclosed in a camera device. In this case, it is possible to grasp the cargo loading box because the camera is photographed in the vertical direction by applying the camera lens as a fisheye lens so that the cargo loading box can be grasped. However, since the front image is unclear and the unnecessary surrounding area is photographed, There is a problem which is not suitable for the system.
