Abstract
A method for estimating a position of a moving object comprises receiving one or more ranging measurements for distances between an object and one or more anchor points from a ranging device, receiving sensing data from one or more sensors, determining a distance and a heading direction of the object relative to a position of the one or more anchor points based on the one or more ranging measurements and the sensing data, applying a mapping using the distance and the heading direction of the object to correct the ranging measurements, and determining a position of the object based on the corrected ranging measurements.
Claims20
A method for estimating a position of a moving object, the method comprising:
- receiving one or more ranging measurements for distances between an object and one or more anchor points from a ranging device;
- receiving sensing data from one or more sensors;
- determining a distance and a heading direction of the object relative to a position of the one or more anchor points based on the one or more ranging measurements and the sensing data;
- applying a mapping using the distance and the heading direction of the object to correct the ranging measurements;
- and
- determining a position of the object based on the corrected ranging measurements.
A device for estimating a position of the device, comprising:
- one or more sensors configured to provide sensing data;
- and
- a processor coupled to the one or more sensors, the processor configured to cause:
- receiving one or more ranging measurements for distances between an object and one or more anchor points from a ranging device;
- receiving sensing data from the one or more sensors;
- determining a distance and a heading direction of the object relative to a position of the one or more anchor points based on the one or more ranging measurements and the sensing data;
- applying a mapping using the distance and the heading direction of the object to correct the ranging measurements;
- and
- determining a position of the object based on the corrected ranging measurements.
