三维影像分析是运动生物力学的重要研究手段之一，广泛地应用于运动技术分析和诊断中。三维跟踪扫描影像分析方法就是摄像机跟踪运动目标来记录运动的图像，并通过专门的图像解析系统解算得到运动目标空间实际三维坐标的方法。应用SIMIMotion的Pan／Tilt／Zoom功能来实现三维跟踪扫描录像分析，并对所得到的三维测量数据的精度进行评价和分析。研究结果表明，在相同的坐标参考系下，由全站仪和影像分析测量得到的24个点的三维空间绝对坐标的平均相差值为0．018±0．003m，三维跟踪扫描影像测量的相对误差可以达到1．97％，这样的测量精度可满足运动技术分析的要求。介绍了实现三维跟踪扫描影像分析的全过程，对影响测量精度的因素进行了初步的分析，并提出了应采取的相应措施。

3D Image Analysis is one of important methods in sport biomechanics, and widely ap- plied in the field of diagnosis and analysis for sport techniques. 3D Image Analysis with Pan/ Tilt/Zoom is that at least two cameras track the moving object to record the image of moving object, and then calculate the spatial coordinates of moving object by using of special motion a- nalysis system. The purpose of this study is to realize 3D Image Analysis with Pan/Tilt/Zoom function using SIMI Motion system, and evaluate the accuracy of 3D coordinate data. The re sults show that in the same Cartesian reference system, the average difference of the spatial ab solute coordinate measured by total station and 3D image analysis is 0.018m± 0. 003m（n= 24） , and the relative error of 3D image tracking analysis is 1.97 %, this accuracy of measure- ment can meet the need of sport technique analysis. In addition, this study introduces the whole procedure to realize 3D Image Analysis with Pan/Tih/Zoom function in details, analyzes the factors influencing the accuracy of measurement, and suggests what should be done to reduce the measurement error.
