- 건설기계의 차량 내에 장착되고, 작업 영역 패턴 및 캡쳐한 사물의 영상을 표시하는 디스플레이와;측방 및 후방에 장착되어 사물의 이미지를 캡쳐하는 적어도 하나 이상의 카메라와;건설기계의 측방 및 후방에 장착되고, 고정 사물 및 이동 사물의 위치를 감지하는 적어도 하나 이상의 센서와;상기 센서를 고려하여 안전거리 영역을 설정하고, 상기 감지한 고정 사물에 대한 센싱 정보를 이용하여 작업 영역의 패턴화 작업을 수행하고, 상기 설정한 안전거리 영역 내에서 이동 사물이 감지된 경우 그 캡쳐된 이미지를 상기 디스플레이에 표시하고 경고음을 울리도록 제어하는 제어부;를 포함하는 건설기계의 사물 감지 장치.
- 제8항에 있어서, 상기 제어부는,건설기계가 정지상태에서 상기 센서에 의해 측정된 고정사물의 위치값을 구하고, 건설기계가 회전 이동한 상태에서 상기 센서에 의해 측정된 사물의 위치값를 갱신한 후,상기 구한 위치값과 상기 갱신한 위치값이 비교하여, 상기 두 위치값이 같으면 상기 갱신한 사물이 상기 작업 영역 패턴 내의 고정사물로 판단하는 것을 특징으로 하는 건설기계의 사물 감지 장치.
- 제8항에 있어서, 상기 제어부는,건설기계가 정지상태에서 상기 센서에 의해 측정된 고정사물의 위치값을 구하고, 건설기계가 회전 이동한 상태에서 상기 센서에 의해 측정된 상기 고정 사물의 위치값를 구한 후, 상기 구한 두 위치값을 이용하여 상기 작업 영역 패턴을 수행하는 것을 특징으로 하는 건설기계의 사물 감지 장치.
