Description

Vehicle side-attached multi-camera device and device for providing information on surroundings of the vehicle using the same {Vehicle-side multi-camera device and vehicle surroundings information providing device}

The present invention relates to a multi-camera device and a device for providing situation information around a vehicle using the same, and more particularly, to a vehicle side-attached multi-camera device detachably attached to a vehicle, and a device for providing situation information around a vehicle using the same. .

When driving, the driver must respond to the changed situation while detecting changes in various situations around the vehicle. If the driver does not properly detect the change in the situation, it may be in a dangerous situation, and a traffic accident may occur due to such a dangerous situation. Even if the driver tries to recognize the change in the surrounding situation, when the surrounding situation is poor, it becomes difficult to detect the change in the situation only by the driver's sense, and may be exposed to a great risk.

The blind spot is called'Blind Spot' and means a place that is invisible. The blind spot, also called'Dead Zone' in military terminology, means a place that calls for death. In the case of vehicles, driving blind spots that cannot be seen through side-mirrors can be seen as a place of death. The blind spot of the side mirror becomes more scary in the winter when the night is long. This is because the blind spot widens at night. This is because it becomes difficult to properly grasp the headlights of cars coming toward the blind spot due to objects being buried in the dark or flashy neon signs. A more serious situation can occur if you have darkened tinting or even snow and rain.

In order to prevent or reduce the occurrence of such a serious situation, various attempts have been made to reduce or eliminate the range of blind spots by installing an auxiliary glass on the side mirror of a vehicle or by installing various sensors and cameras.

Since the driver cannot rely solely on the driver's senses to immediately detect changes in surrounding conditions and respond to dangerous situations, safety convenience equipment such as various sensors and cameras that can help the driver are installed and operated in the vehicle.

These safety convenience devices reduce driver's attention and effort, reduce driving fatigue, reduce the area of blind spots, reduce the incidence of traffic accidents, and attach a new type of vehicle that can prevent the development of large-scale accidents. There is a need to develop a multi-camera device.
