Target value detection for unmanned aerial vehicles
First Claim
1. A method for target value detection, the method comprising:
- receiving a first ultrasonic response using a first transducer of an unmanned aerial vehicle responsive to a first ultrasonic signal transmitted using the first transducer;
receiving a second ultrasonic response using a second transducer of the unmanned aerial vehicle responsive to a second ultrasonic signal transmitted using the second transducer, wherein the second transducer has a wider beam pattern than the first transducer;
determining whether the first ultrasonic response includes a target value within a first range area associated with the first transducer;
determining whether the second ultrasonic response includes the target value within a second range area associated with the second transducer, wherein the second range area includes an inner region and an outer region and the inner region corresponds to the first range area;
responsive to determining that the first ultrasonic response does not include the target value within the first range area and determining that the second ultrasonic response does not include the target value within the inner region, determining whether the second ultrasonic response includes the target value within the outer region; and
responsive to determining that the second ultrasonic response includes the target value within the outer region, generating a confidence value based on a detection of the target value using the second transducer and not using the first transducer, wherein the target value is reflected from an object and the confidence value indicates a likelihood of a position of the unmanned aerial vehicle with respect to the object.

Abstract
Target value detection for an unmanned aerial vehicle is described. The unmanned aerial vehicle includes a first transducer that transmits a first ultrasonic signal and receives a first ultrasonic response and a second transducer that transmits a second ultrasonic signal and receives a second ultrasonic response. The second transducer has a wider beam pattern than the first transducer. Determinations are made as to whether either or both of the first or second ultrasonic responses includes a target value within range areas associated with the respective beam patterns of the first and second transducers. A confidence value is generated based on the determinations. The target value is reflected from an object and the confidence value indicates a likelihood of a position of the unmanned aerial vehicle with respect to the object.
