Method and system for region of interest calibration parameter adjustment of tracking systems |
摘要 |
A method for adjusting parameters of a calibration model in a position sensing system including a sensor for obtaining a measurement indicative of a location of an object, the method including: a) providing an initial set of model parameters for determining a relationship between a sensor measurement and a location value within a predetermined volume of location values; b) selecting a plurality of sub-segments of location values within the range of location values; c) providing for each of the selected plurality of sub-segments of location values a local set of model parameters for determining a relationship between a sensor measurement and a location value within the selected sub-segment of location values; d) obtaining a measurement from the sensor; e) determining an estimate of the location of the object from the sensor measurement and the initial set of model parameters; and f) identifying at least one of the selected sub-segments of location values related to the estimate of the location of the object. |
