Abstract

本发明提供一种用于机器人实时模仿人类动作的方法及其机器人,所述方法包括:拍摄被模仿者做出模仿动作的视频图像,从每一帧图像中提取骨架关键点的空间坐标;基于提取的空间坐标,获取被模仿者的各个部位各自的向量化表示;按照预设的各个骨段的归一化长度,对各个骨段的空间向量进行修正;将修正后的向量化表示在低维投影空间进行投影,获取部位的动作姿态类别;根据获取的动作姿态类别来确定每个部位的机器人模仿动作;将各个部位的机器人模仿动作分别转换为机器人对应部位的各个关节的电机参数,并根据电机参数来控制机器人的各个部位共同执行模仿动作。本发明以较低的运算代价得到准确性和泛化性均较为理想的模仿结果。
