Abstract
A work machine includes an implement that carries an object. A vision system detects the endpoints of the object relative to the implement and provides those endpoints to a damage avoidance control system. The damage avoidance control system generates control signals to avoid a collision between the object and a part of the work machine.
Claims13
A computer implemented method, comprising:
- receiving a vision system input from a vision system, the vision system input being indicative of a field of view;
- identifying, with an object endpoint detection system, a set of points corresponding to an object carried by an implement of a work machine based on the vision system input;
- identifying, with the object endpoint detection system, from the set of points, a set of endpoints based on a distance that the endpoints are displaced from the implement;
- and
- generating, with a damage avoidance control signal generator, an actuator control signal to control movement of the object based on a location of the set of endpoints relative to the implement to avoid contact between the object and a protected portion of the work machine.

A damage avoidance control system, comprising:
- a vision system that generates a vision system signal indicative of a field of view captured by the vision system;
- an object endpoint detection system that identifies a set of points corresponding to an object carried by an implement of a work machine based on the vision system signal and that identifies, from the set of points, a set of endpoints based on a distance that the endpoints are displaced from the implement;
- and
- a damage avoidance control signal generator that generates an actuator control signal to control movement of the object based on a location of the set of endpoints of the object relative to the implement to avoid contact between the object and a protected portion of the work machine.
1 more element
A work machine, comprising:
- a machine frame;
- an implement movably coupled to the machine frame;
- an actuator configured to drive movement of the implement relative to the machine frame;
- a vision system that generates a vision system signal indicative of a sensed field of view;
- an object processing system that identifies a location of an endpoint of an object carried by the implement relative to the implement based on the vision system signal;
- and
- a control signal generator that generates an actuator control signal to control movement of the object to avoid contact between the of the object and a protected portion of the work machine based on the identified location of the endpoint of the object.
