SYSTEMS AND METHODS FOR SENSING AND TRACKING RADIATION BLOCKING OBJECTS ON A SURFACE |
摘要 |
<p>Various system and methods for estimating the position of one or more radiation blocking objects on a surface are disclosed. A plurality of radiation sources and radiation sensors are positioned about the surface. A plurality of sectors corresponding to the position of at least some of the radiation blocking objects relative to each of the radiation sensors is determined based on a radiation intensity signal for each radiation sensor. The position of the radiation blocking objects is estimated by analyzing various combinations of the sectors. In some embodiments, the size of a radiation blocking object may be estimated based on characteristics of a polygon corresponding to a combination of sectors.</p> |
