摘要： A positioning system, in particular, six-dimensions positioning system of a target comprising N light source(s) with respect to a shadow sensor, 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 target 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.

摘要： La présente invention concerne un capteur rotatif optique de mesure de position angulaire absolue destiné à être utilisé en combinaison avec des moteurs miniatures tournant à des vitesses de plusieurs centaines de milliers de tours/minute. La plupart des capteurs de position rotatifs actuels utilisent un disque fixé au rotor, sur lequel est marqué un code, ainsi qu'un capteur qui lit la valeur du code à un ou plusieurs endroits particuliers du disque. Contrairement à ces capteurs, le système proposé utilise la totalité du marquage du disque pour le calcul de la position absolue. Cette particularité confère à l'invention plusieurs avantages, dont certains sont cumulables :
• dimension très faible du capteur,
• possibilité d'atteindre des vitesses de rotation de l'ordre de 600'000 tours/min,
• augmentation de la résolution par interpolation si le flou de mouvement est négligeable, c.à.d. à des vitesses de rotation réduites (max 20'000 tours/min),
• compensation automatique du décentrage de l'axe,
• calibration adaptative en fonction de la non-uniformité de l'éclairage et du fixed-pattern du capteur d'image.摘要翻译： 该装置具有计算单元，该计算单元被编程用于当标记盘即编码盘（2）在图像采集期间执行大于半标记周期的位移时，对转子的绝对角位置（90）进行近似测量 图像传感器 计算单元执行对转子的位置的近似和精确的测量，以便当光盘在图像传感器获取图像期间执行小于半标记周期的位移时获得确定的角位置。 还包括用于测量转子的绝对角位置的方法的独立权利要求。

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.
