Systems, methods, and devices for verification of position estimation using an orientation sensor

A method of determining the location of the first object (10) may include receiving signals at a second object (20) from a plurality of measurement points (11) on the first object (10), estimating locations of the plurality of measurement points (11) on the first object (10), determining an estimate...

Zusammenfassung:A method of determining the location of the first object (10) may include receiving signals at a second object (20) from a plurality of measurement points (11) on the first object (10), estimating locations of the plurality of measurement points (11) on the first object (10), determining an estimate of a location of the first object (10), determining a first measurement of an orientation of the first object (10) based on the estimating of the locations of the plurality of measurement points (11) on the first object (10), and determining a second measurement of the orientation of the first object (10) based on measurements by an orientation sensor (12) on the first object (10). The method may include estimating an error of the estimate of the location of the first object (10) based on a difference between the first and second orientation measurements and adjusting a movement of the second object (20) based on the estimated error.
