“…The development of 3D robot vision is actually based on the improvement of vision algorithms and 3D sensors. 2 Through decades of innovation, vision algorithms in the robot vision system have formed three classes: human–robot interaction, 3 –13 identification and perception, 14 –20 and movement decision. 21 –34 Corresponding to these classes, the main applications contain gesture recognition, 3,5,9,11,12,35 target tracking, 10,36 –39 human eye tracking, 13,40 map building, 20,25,41 –44 scene understanding, 33,34 object recognition, 16 –19,45,46 location and pose recognition, 21 –23 autonomous navigation,…”
