본 발명은 차량용 레이더의 보정 장치 및 그 방법이 개시된다. 본 발명의 차량용 레이더의 보정 방법은, 제어부가 레이더부를 통해 차량의 전방 타겟을 탐지하는 단계; 제어부가 레이더부터로부터 타겟의 탐지결과를 입력받아 정지타겟 여부를 판단하는 단계; 제어부가 정지타겟 여부를 판단하여 정지타겟인 경우, 차량상태 입력부로부터 차량의 상태를 입력받아 차량의 직진주행 여부를 판단하는 단계; 제어부가 직진주행 여부를 판단하여 직진주행인 경우 레이더부의 비틀림 각도를 계산하는 단계; 제어부가 비틀림 각도의 신뢰도를 판단하여 신뢰도에 따른 가중치를 부여하는 단계; 및 제어부가 가중치를 부여하여 비틀림 각도를 보정하여 출력하는 단계;를 포함하는 것을 특징으로 한다.
The present invention discloses an apparatus for calibrating a vehicle radar, and a method thereof. The method for calibrating a vehicle radar according to the present invention comprises the steps of: detecting, by a control unit, a front target of a vehicle through a radar unit; receiving, by the control unit, a detection result of the target from the radar unit to determine whether the target is a static target; receiving, by the control unit, a vehicle state of the vehicle from a vehicle state input unit to determine whether the vehicle travels in a straight line, if the target is a static target after determining whether the target is a static target; calculating, by the control unit, a twist angle of the radar unit, if the vehicle travels in a straight line after determining whether the vehicle travels in a straight line; determining, by the control unit, the reliability of the twist angle and assigning a weight according to the reliability; and outputting, by the control unit, the twist angle after calibrating the twist angle by assigning a weight. In the step of assigning a weight according to the reliability, the control unit sets a group for a detection result and calculates a standard deviation from the group, and multiple sections for the standard deviation are set to perform calibration by assigning different weights to the twist angle according to each section. Therefore, the faster calibration is possible.
