Beschreibung
Zusammenfassung:	The present invention provides a calibration apparatus and a calibration method for converting coordinates by using information of respective photographed images and distance information wherein changes of coordinates are calculated by using a flat plate member including a vertex and by using a corresponding pair of lines comprising a vertex which is estimated from the distance information, and a vertex which is extracted from the image information. Accordingly, it is possible to overcome the limitations of the position where the laser sensor, the camera, and the plate member are arranged. 본 발명은 각각 촬영된 이미지 정보 및 거리 정보를 이용하여 좌표변환을 하는 캘리브레이션 장치 및 방법을 제공하며, 꼭지점을 포함하는 평판부재를 이용하고, 상기 거리 정보로부터 예측된 꼭지점과 상기 이미지 정보로부터 추출된 꼭지점으로 이루어지는 대응쌍을 이용하여 좌표변화를 구현한다. 이에 따라, 레이저 센서 및 카메라와 상기 평판부재가 배치되는 위치의 한계를 극복할 수 있다.
