Abstract
Aiming at the the problem of feeding for the elderly or the upper limb amputees
a design scheme of feeding assistant manipulator based on machine vision is proposed.Aiming at the design requirement of the system
the structure and detection principle of Adaboost face detection classifier based on Haar feature are analyzed
and the visual-based object tracking proportional-integral-differential(PID) control algorithm is combined to make use of its features of fast response and strong robustness
effective realize requirement of face tracking.Finally
the manipulator can complete the detection of the human face and feeding-assistant work through feedingassistant debugging
