Abstract
Tracking a person in a building can be performed by obtaining a building layout with respect to a surrounding geography and tracking movement of the person using a monitoring device carried by the person. A correction angle can be calculated to normalize tracked movement of the person with respect to a skew angle of the building layout. The correction angle can be applied to the tracked movement of the person or the building layout.
Claims29
A method for tracking a person in a building, comprising:
- obtaining a building layout of a building with respect to a surrounding geography;
- tracking movement of the person with respect to the building using a monitoring device carried by the person;
- calculating a correction angle to normalize tracked movement of the person with respect to a skew angle of the building layout;
- and
- applying the correction angle to at least one of the tracked movement of the person and the building layout.
A system for tracking a person in a building, comprising:
- a monitoring station operable to receive data signals associated with a tracked movement of the person in the building as detected by a monitoring device carried by the person;
- a correction module configured to calculate a correction angle to normalize the tracked movement of the person with respect to a skew angle of a layout of the building;
- and
- a tracking module configured to apply the correction angle to at least one of the tracked movement of the person and the building layout and to track the movement of the person by estimating a location of the person from the data signals.
A system for tracking a person in a building, comprising:
- a monitoring station operable to receive data signals comprising a positional information associated with a movement of the person in the building as detected by a monitoring device carried by the person;
- a tracking module configured to track the movement of the person with respect to a building layout of the building by estimating a location of the person from the data signals;
- and
- a forward look-ahead path correction module for correcting a movement offset of the person when a path of the movement of the person is blocked by a wall of the building and steps of the person are continued to be detected, the forward look-ahead path correction module configured to:
- identify a straight path and two angled paths on opposite sides of the straight path for path continuity candidates;
- determine whether a path continuity candidate exists for the straight path or at least one of the two angled paths, wherein the path continuity candidate intersects a wall of the building layout;
- and
- project a position of the person onto an existing path continuity candidate to place the projected position within the building layout, wherein the projected position along the path continuity is determined according to a number of the detected steps of the person.
