Excavator limb length determination using a laser distance meter
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 DLDM and θINC between the LDM and the reflector, and the controller is programmed to generate θB at a plurality of boom positions, generate θS at 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 DLDM and θINC, build a set of H, D measurements and a corresponding set of θB, θS, and execute a linear least squares optimization process based on the H, D set and corresponding set of θB, θS to determine and operate the excavator using LB and LS.
