본 발명은 자동차용 보행자 사과 예방 장치 및 방법에 관한 것으로, 본 발명에 의하면, 이격거리(x)로 이격되어서 제자리에서 회전하는 제1,2 열화상 카메라(110,120)와, 회전하고 있는 제1,2 열화상 카메라(110,120)의 현재 회전각인 제1,2 회전각(θ1,θ2)을 검출하고, 제1,2 열화상 카메라(110,120)로부터 수신한 온도정보에 따라서 보행자 유무를 판단하고, "보행자 있음"이라고 판단한 경우에는 제1,2 회전각(θ1,θ2)과 이격거리(x)를 보행자 위치 산출 프로그램 저장부(150)로 출력하는 컨트롤러(140)와, 컨트롤러(140)로부터 수신한 이격거리(x)와 제1,2 회전각(θ1,θ2)을 기초로 열화상 카메라(110,120)로부터의 보행자(M)까지의 거리(y)를 산출하는 보행자 위치 산출 프로그램이 저장되어 있는 보행자 위치 산출 프로그램 저장부(150)를 포함하여 구성되는 것을 특징으로 하고, 이에 의하면 매우 간단한 구성으로 보행자의 거리를 측정하여서 보행자의 사고 위험을 미연에 방지할 수 있는 이점이 있다.

    The present invention relates to a pedestrian accident prevention device for an automobile and a method thereof. The pedestrian accident prevention device for an automobile comprises: first and second thermal imaging cameras (110, 120) spaced a distance (x) from each other and rotating in place; a controller (140) for detecting first and second rotation angles (θ1, θ2), which are the current rotation angles of the rotating first and second thermal imaging cameras (110, 120), determining the presence or absence of a pedestrian according to temperature information received from the first and second thermal imaging cameras (110, 120), and outputting the first and second rotation angles (θ1, θ2) and the distance (x) to a pedestrian position calculation program storage unit (150) if it is determined that "there is the pedestrian"; and the pedestrian position calculation program storage unit (150) for storing a pedestrian position calculation program for calculating the distance (y) from the thermal imaging cameras (110, 120) to the pedestrian (M) based on the distance (x) and the first and second rotation angles (θ1, θ2) received from the controller (140). Therefore, the pedestrian accident prevention device can measure the distance to the pedestrian with a very simple structure, thereby preventing the risk of a pedestrian accident.
