Research on Recognition System of Facial Expression for the Robot to Help Elder and Disabled

摘要

In view of the inflexibility of human-computer interaction for the robot to help elder and disabled, this paper introduces the recognition technology of facial expression to integrate with the robot. So, the robot can perform corresponding actions according to different facial expression, which greatly improves the convenience for human to control robot. This thesis mainly focuses on the accuracy of face location, the recognition rate of expression recognition and the application of expression recognition system. This thesis is trained and tested on the HELEN face dataset and the self-built face dataset respectively. The tests achieve good results in both face alignment experiments and facial expression recognition experiments. Finally, by combining the expression recognition system with robot platform of helping elder and disabled, the purpose of controlling the movement of the robot by expression information is realized, which proves the feasibility of the method.
