Abstract
A framework comprises a laser distance meter (LDM), reflector, and excavator comprising a chassis, linkage assembly (LA), boom and stick sensors, implement, and control architecture. The LA comprises a boom and stick defining LA positions. The LDM is configured to generate a Dand θbetween the LDM and the reflector at a node, and the control architecture comprises actuator(s) and a controller programmed to execute at successive LA positions an iterative process (comprises generating θ, generating θ, and calculating a height H and a distance D between the node and the LDM based on Dand θ), build a set of H, D measurements and a corresponding set of θ, θfor n LA positions, and execute a linear least squares optimization process based on the H, D set and corresponding set of θ, θto determine and operate the excavator using L, L, θ, and θ.
