Abstract
A system is provided for determining the plausibility that a current ground surface on which a construction machine is located conforms to a prior survey of that ground surface. A controller is provided with a digital model defined within a reference system external to the construction machine. The controller determines a current relative orientation and an expected relative orientation, of at least one sensor pair of a plurality of distance sensors, relative to each other and relative to a reference plane defined in the digital model. The controller compares those orientations to confirm whether the current relative orientation conforms to the expected relative orientation.
