摘　　要：针对太极拳教学现状,基于自主学习理论,提出设计基于关键帧提取技术和三维坐标变换技术的太极拳运动考评系统。本文采用运动捕捉技术采集了24式太极运动数据,以关键帧提取技术为基础,设计了运动时间对比模块,解决了运动速度对比问题;以三维坐标平移变换和朝向旋转变换技术为基础,设计了运动空间对比模块,解决了运动位置对比问题;结合运动速度对比与运动位置对比,系统能够自动地对教学运动素材进行对比与评价,满足了学生自主学习需求。This essay design and implement a simulation study system which could automaticly make a evaluation on the quality of students,based on classic 24 Taiji sport original data as teaching source material.This essay designs movementspeed and time comparison module,which solves teaching sport speed comparison question,based on Key frame extraction technology.Besides,solve the inconsistent question on people＇s height,based on The three-dimensional coordinate transform scaling technology.We design movement space contrast module and solve movement position contrast issue,based on The 3D coordinates of translational and rotational transform technology.Therefore,this system could automaticly make a evaluation on teaching sport source.This meet the students＇ requirement of autonomous learning.
