The present invention provides a pedestrian protection apparatus, which comprises: a photographing unit which photographs a far infrared (FIR) image of an object in front of a vehicle; a sensor unit which is mounted on a bumper of the vehicle and senses at least one of a change in acceleration and a change in pressure of the bumper caused by a collision between the vehicle and the object located in front of the vehicle; and a control unit which determines whether or not the object is a pedestrian candidate in accordance with the FIR image photographed by the photographing unit, determines whether or not the pedestrian candidate is a pedestrian in accordance with at least one of the change in the acceleration and the change in the pressure sensed by the sensor unit, and operates a protection means for pedestrian protection in response to the pedestrian candidate being identified as the pedestrian. Therefore, the present invention can improve the collision detection performance and the operating reliability of the protection apparatus for preventing damage to a guardian.
본 발명은 차량 전방의 FIR(Far InfraRed) 영상을 촬영하는 촬영부, 차량의 범퍼에 장착되어 차량의 전방에 위치한 물체와 차량 간의 충돌에 따른 범퍼의 가속도 변화 및 압력 변화 중 적어도 하나를 센싱하는 센서부, 및 촬영부를 통해 촬영한 FIR 영상을 기초하여 물체가 보행자 후보인지 여부를 판단하고, 센서부를 통해 센싱한 가속도 변화 및 압력 변화 중 적어도 하나에 기초하여 보행자 후보가 보행자인지 여부를 판단하며, 보행자 후보가 보행자인 것을 식별한 것에 응답하여 보행자의 보호를 위한 보호수단을 작동시키는 제어부를 포함하는 것을 특징으로 한다.
