Irregular feature mapping |
摘要 |
Disclosed herein are methods and systems for mapping irregular features. In an embodiment, a computer-implemented method may include obtaining tracking data that has dead reckoning tracking data for a tracked subject along a path and performing shape correction on the tracking data to provide a first estimate of the path. |

1. A computer-implemented method of tracking a trackee, the method being implemented by a computer that includes a physical processor, the method comprising:
obtaining tracking data for a tracked subject along a path, the tracking data including data from a dead reckoning sensor; and performing shape correction on the tracking data to provide a first estimate of the path, wherein performing shape correction includes describing the path by a set of linear segments with a width less than a series of decreasing thresholds corresponding to coarse shape correction and fine shape correction. |
