a Principle of shape assessment with the GAM. b Arrangement of sensors on the bottom surface of RM. c Comparison of the RM’s shapes captured by the GAM and binocular stereo camera. d Root-mean-square deviation (RMSD) values of the GAM-monitored shape when using the camera-measured result as reference. e Structure of the ANN model in BSM. f Test loss of the ANN over the epoch. g Time evolution of the adaptive programming operation. h Experiment setup for far-field measurement.
