  6. 5. Classication framework formonitoring calibration ofautonomous waist-actuated minevehicles

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Per Landström; John Sandström; [2020]
    Keywords : SVM; NDT; machine learning; scan matching; hinge angle sensor; calibration detection;

    Abstract : For autonomous mine vehicles that perform the ”load-haul-dump” (LHD) cycle to operate properly, calibration of the sensors they rely on is crucial. The LHD cycle refers to a vehicle that loads material, hauls the material along a route and dumps it in an extraction point. READ MORE
