摘要: 提出从人体姿态估计的角度实现人与NAO机器人的互动交流。用AdaBoost算法训练得到人体部件检测器,利用得到的部件检测器在图片中寻找到对应部件的若干候选区域,在寻找的过程中兼顾部件的位置和方向。依据提出的评价指标评价这些候选区域,从中选出最优。以NAO机器人为实验平台,在其动作可达范围内实现对人体动作姿态的识别与模仿,达到较好的动作空间一致性和时间一致性。实验结果证明该算法可有效识别和模仿人体姿态。

Abstract: This paper takes a view of human pose and action recognition to realize human-robot interaction. A part detector for each human body part is obtained by AdaBoost algorithm. With these detectors, several candidate regions for the corresponding body part are found. During the finding process, the position and orientation of parts are both considered. These candidate regions are evaluated by using several defined evaluation indexes in order to select an optimal one. Human pose recognition and action imitation are implemented by using a NAO robot as test bench, and NAO’s performance shows good spatial consistence and temporal consistence within its ability of operation. The result shows that the algorithm can effectively identify and imitate human posture.

Key words: human-robot interaction, NAO robot, human pose recognition, AdaBoost algorithm, part detector, human posture imitation
