Abstract
A framework comprises a laser distance meter (LDM), reflector, and excavator comprising a boom, a stick, boom and stick sensors, implement, and a controller. The LA comprises a boom and stick defining LA positions. The LDM is configured to generate a Dand θbetween the LDM and the reflector, and the controller is programmed to generate θat a plurality of boom positions, generate θat a plurality of stick positions, and calculate a height H and a distance D between a node on the stick and the LDM based on Dand θ, build a set of H, D measurements and a corresponding set of θ, θ, 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 Land L.
