The purpose of this research is to develop a handheld pole mounted camera system that can indicate stereoscopic view. This camera system will be used to search for inside of narrow spaces such as buildings and vehicles transformed by the earthquake or some accidents. The system has a stereo camera and Head Mounted Display(HMD). This stereo camera is mounted on the toe of a handheld pole. A firefighter attach a HMD in his head, and he insert a stereo camera in narrow space, when he want to use this system. In this paper, we discussed a summary of this stereo camera system. And we reported three experiments for estimation of this system.
