Description

광각영상매체를 이용한 자동차용 전방향미러시스템{Omni-directional automobile mirror system using wide-angle optical method}Omni-directional automobile mirror system using wide-angle optical method}

본 발명은 광각영상매체를 이용한 자동차용 전방향미러시스템에 관한 것으로, 더욱 상세하게는 어안렌즈나 볼록거울과 같은 광각영상매체를 사용하는 사각지대 없는 전방향미러시스템을 제공코자 한 것이다.The present invention relates to an omnidirectional mirror system for a vehicle using a wide-angle image medium, and more particularly, to provide an omnidirectional mirror system using a wide-angle image medium such as a fisheye lens or a convex mirror.

최근 자동차 생산 및 사용이 기하급수적으로 증가함에 따라 자동차사고도 따라서 늘고 있다.As the production and use of automobiles has increased exponentially, automobile accidents have been increasing accordingly.

그 주요한 원인을 보면 음주운전, 난폭운전, 졸음운전, 부주의와 같은 운전자과실에 의한 사고나 야간, 우천, 안개 등으로 인한 시야 불량과 같은 환경적인 원인에 의한 사고와 함께 큰 부분을 차지하고 있는 것이 바로 사이드/백미러가 가지고 있는 사각지역으로 인한, 다시 말해서 자동차 구조상의 결함으로 인한 사고이다.Its main causes include accidents caused by driver's negligence such as drunk driving, violent driving, drowsy driving, and carelessness, and environmental accidents such as poor visibility due to nighttime, rainy weather, fog, etc. The accident is caused by a blind area of the side / rear mirror, that is, a defect in the structure of the vehicle.

모든 자동차에는 도 1에 도시된 바와 같이 적어도 2개의 사이드미러(11)와 1개의 백미러(12)가 장착되어 있으며 각각은 자동차(10) 좌우후방의 극히 일부만을 반사하여 보여주기 때문에 좌우측에 상당부분의 사각지역이 생긴다. 또 각각의 미러는 장착 위치가 떨어져 있어 운전자가 한번에 자동차 주변상황을 판단할 수 없는 문제점을 안고 있다. 특히 우천 시에는 사이드미러나 뒷유리창의 빗물로 인해 주변상황의 식별이 더욱 어렵게 된다.All vehicles are equipped with at least two side mirrors 11 and one rear view mirror 12 as shown in FIG. 1, and since each reflects only a part of the left and right rear sides of the vehicle 10, a considerable portion is provided on the left and right sides. A blind spot of is formed. In addition, each mirror has a problem that the driver can not determine the situation around the car at a time because the mounting position is apart. Especially in rainy weather, it is more difficult to identify the surrounding situation due to rain from the side mirrors or the rear window.

이러한 사각지역을 없애기 위하여 기존 사이드/백미러(11)(12)에 여러 가지 볼록거울을 추가로 장착하는 방법이 나와 있으나 이를 이용할 경우 사용자는 더 많은 미러들을 짧은 시간에 보아야 하므로 한번에 주변상황 판단이 어려우며 우천시발생하는 문제점등을 해결할 수 있는 해결책으로는 미흡한 실정인바, 이를 해결할 수 있는 신규한 구성의 미러 개발이 시급히 요구되고 있는 실정이다.In order to eliminate this blind spot, there are methods for attaching various convex mirrors to the existing side / rear mirrors (11) and (12), but when using this, the user needs to see more mirrors in a short time, so it is difficult to determine the surrounding situation at once. As a solution to the problems occurring during rainy weather is insufficient, it is urgently required to develop a new mirror configuration to solve this problem.

이에 본 발명자는 상기한 바와 같은 기존의 자동차에 장치되어 있는 미러가 가지는 제반 문제점을 해결코자 연구 개발한 것으로서, 어안렌즈나 볼록거울과 같은 광각영상매체를 사용하여 주변환경을 득하고 이를 통하여 영상처리함으로서 자동차 주변의 사각지대가 없도록 하여 보다 안전한 운행을 도모할 수 있도록 함에 본 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.Accordingly, the present inventors have developed and researched to solve all the problems of the mirrors in the existing automobiles as described above. By using a wide-angle image medium such as a fisheye lens or a convex mirror, the environment is obtained and image processing is performed. The present invention has been completed with the technical problem of the present invention to enable safer operation by eliminating blind spots around the vehicle.
