摘要： A positioning system, in particular, six-dimensions positioning system of a shadow sensor with respect to a constellation of light sources is provided. The sensor can be a shadow sensor and has a mask and a 2D imager. By recording the shadow of the mask cast by each light source on the imager, and by properly multiplexing the light sources, the system can compute the 6D position of the shadow sensor with respect to the constellation of light sources. This computation is based, in part, on treating the shadow of the mask cast on the imager as the equivalent of the projection of light in a pinhole or projective camera. In one embodiment, the system is applied in a surgical domain. In another embodiment, the system is rapidly deployed.

摘要： A positioning system, in particular, positioning in six dimensions of a sensor with respect to an assembly composed of a multitude of LEDs, is provided. The sensor is a shadow sensor and has a mask and a 2D imager. By recording the shadow of the mask cast by each LED on the imager, and by properly multiplexing the LEDs, the system can compute the 6D position of the LED assembly with respect to the shadow sensor. This computation is based, in part, on treating the shadow of the mask cast on the imager as the equivalent of the projection of light in a pinhole camera.
