Abstract
A work machine, a first method of defining a virtual 3D exclusion zone, and a second method of preventing collisions involving a work machine are disclosed. The work machine comprises a body, an implement arm, an imaging assembly, and an electrohydraulic assembly configured to prevent the implement arm from intersecting a 3D exclusion zone. The first method comprises scanning a local environment, generating a virtual 3D representation, identifying key structures, and generating a virtual 3D exclusion zone encompassing the key structures. The second method comprises defining a virtual 3D exclusion zone, monitoring a motion of the work machine, and adjusting the motion to avoid an intersection between the work machine and the 3D exclusion zone. The 3D exclusion zone may be implemented for a number of machines, environments, and key structures without unduly removing control from a human operator.
