Abstract

A framework comprises a laser distance meter (LDM), first and second laser reflectors at respective nodes, and an excavator including a chassis, a linkage assembly (LA) including a boom and stick, an implement including the nodes and tilting about axis TA, an implement sensor generating signal θ, and architecture. The LDM generates LDM distance signals Dand LDM angle of inclination signals θbetween the LDM and the laser reflectors. The architecture comprises LA actuators and a controller programmed to determine the TA relative to horizontal based on θand execute an iterative process to curl the excavating implement and create bucket angles, align the LDM and the first node to determine a set of rotated IDV, align the LDM and the second node to determine a set of rotated IPV, and determine implement dimensions between the nodes based on the set of rotated IDV and IPV.
