Abstract
A method of determining cable angle includes acquiring image data of a cable and a load coupled to a rotorcraft using three-dimensional (3D) spatial perception system, constructing an image of the cable and load using the image data, and determining the angle of the cable relative to the external load at an interface of the cable and external load based on the image.
Claims15
A method of determining cable angle, comprising:
- acquiring, by a three-dimensional (3D) spatial perception system carried by a rotorcraft, image data of a cable and a load coupled to the rotorcraft by the cable;
- and
- determining an angle defined between at least one of (a) the cable and the external load, and (b) the cable and the rotorcraft using the image data acquired by the 3D spatial perception system.
A three-dimensional perception system for determining a cable angle, comprising:
- a sensor;
- a processor operatively connected to the sensor;
- and
- a non-transitory machine-readable memory communicative with the processor and having instructions recorded thereon that, when read by the processor, cause the processor to:
- acquire image data of a cable and an external load coupled to a rotorcraft;
- construct an image of the cable and the external load using the image data;
- and
- determine an angle defined between at least one of (a) the cable and the external load, and (b) the cable and the rotorcraft, based on the image.
