Optical Indoor Positioning

چکیده
Central Idea The central idea of the new indoor positioning system is based on the fundamentals of stereo photogrammetry. But instead of using a second camera, we replace it with a device (called laserhedgehog) that projects well-distributed laser spots as flexible reference points on the ceiling, walls and furniture in any indoor environment (Fig. 1). The projecting light source consists of several focused laser-beams that originate from a static, welldefined central point. The 3D directions of the laser-beams are also precisely known through a previous calibration.
