However, in practice, the performance of computer vision algorithms is challenged by insufficient or biased training, observation noise, cluttered background, etc. By leveraging <em>Bayesian Deep Learning<\/em> (BDL), we have developed a novel, reliable vision-based framework to assist upper-limb prosthesis grasping during arm reaching. This framework can measure different types of uncertainties from the model and data for grasping target recognition in realistic and challenging scenarios. A probability calibration network was developed to fuse the uncertainty measures into one calibrated probability for online decision-making. We formulated the problem as the prediction of grasping target while arm reaching. Specifically, we developed a 3D simulation platform to simulate and analyze the performance of vision algorithms under several common challenging scenarios in practice. In addition, we integrated our approach into a shared control framework of a prosthetic arm and demonstrated its potential at assisting human participants with fluent target reaching and grasping tasks.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;2_5&#8243; _builder_version=&#8221;4.4.0&#8243;][et_pb_text admin_label=&#8221;Resources&#8221; _builder_version=&#8221;4.4.0&#8243; hover_enabled=&#8221;0&#8243;]<\/p>\n<h2 style=\"text-align: left;\">Resources:<\/h2>\n<p>&nbsp;<\/p>\n<ul>\n<li><a href=\"https:\/\/ieeexplore.ieee.org\/document\/9113325\">IEEE <span class=\"il\">Transactions<\/span> on Cybernetics 2020 Article<\/a><\/li>\n<li><a href=\"https:\/\/research.ece.ncsu.edu\/wp-content\/uploads\/sites\/7\/2020\/06\/tcyb2020-upperlimb-appendix.pdf\">Appendix<\/a><\/li>\n<li><a href=\"https:\/\/youtu.be\/fFZdTbNutFc\">Video<\/a><\/li>\n<\/ul>\n<p>This work was a collaboration between the ARoS Lab and the <a href=\"https:\/\/nrel.web.unc.edu\/\">Neuromuscular Rehabilitation Engineering Laboratory (NREL)<\/a> at UNC Chapel Hill \/ NC State.
