Claims (7)
- 이동로봇에 부착되는 영상획득수단과, 상기 영상획득수단으로 적외선을 발광시키기 위하여 고정물에 부착된 랜드마크의 적외선 발광소자들로 구성된 복수개의 적외선 발생수단을 포함하며, 상기 적외선 발광소자들의 배열에 의해 상기 적외선 발생수단의 중심좌표와 방위가 나타내지는 좌표확인시스템에 있어서,상기 복수개의 적외선 발생수단은 발광을 위한 제1 펄스온타임과 비발광을 위한 제1 펄스오프타임으로 이루어진 제1 주기의 펄스를 가지고,상기 영상획득수단은 수광을 위한 제2 펄스온타임과 비수광을 위한 제2 펄스오프타임으로 이루어진 제2 주기의 펄스를 가지며,상기 제2 펄스온타임 동안 상기 제1 펄스온타임의 적외선 발광을 수광하는 것을 특징으로 하는 실내항법 좌표확인시스템.
- 제1항에 있어서, 상기 제1 펄스온타임는 상기 제2 펄스온타임 보다 대역폭이 작은 것을 특징으로 하는 실내항법 좌표확인시스템.
- 제1항에 있어서, 상기 제1 주기가 상기 제2 주기보다 작은 것을 특징으로 하는 실내항법 좌표확인시스템.
- 제1항에 있어서, 상기 이동로봇의 이동에 의해 해당 적외선발광소자에 접근 할 때 상기 제1 펄스온타임과 상기 제2 펄스온타임이 동조되도록 상기 제1 주기와 제2 주기를 동조시키는 것을 특징으로 하는 실내항법 좌표확인시스템.
- 제1항에 있어서, 상기 이동로봇의 이동에 의해 인접 적외선발광소자가 발광되도록 하는 수신수단이 상기 적외선발광소자에 더 포함된 것을 특징으로 하는 실내항법 좌표확인시스템.
- 제1항에 있어서, 상기 적외선발광소자의 중심좌표를 기준원점으로 하는 좌표축들에 대한 영상획득수단의 중심축 사이의 x축과 y축의 각도를 상기 적외선발광소자의 발광 센싱이 가능한 임계각이라 할 때 상기 적외선발광소자의 상기 영상획득수단에 대한 천정각이 임계각 이상일 경우 상기 제1 펄스온타임의 대역폭을 증가시키는 것을 특징으로 하는 실내항법 좌표확인시스템.
- 제6항에 있어서, 상기 임계각을 상기 영상획득수단의 영상인식률이 급격히 저하되는 것을 각인 것을 특징으로 하는 실내항법 좌표확인시스템.
