三维运动影像分析通常采用的算法是直接线性变换法（DLT）,而控制点的空间三维坐标是应用直接线性变换法进行标定基本参数,它目前是通过三维标定框架的已知控制点的坐标所获得的。由于三维标定框架所覆盖的空间有限,对于较大运动范围运动项目的三维运动影像分析会造成较大的误差。研究目的是在全站仪（Topcon GPT-3002 N）为硬件的基础上,以对象编程语言C#为开发工具开发了三维影像分析控制点测量与坐标转换软件系统。此系统为对运动空间任意布置的控制点,或标定框架上的控制点的三维坐标的精确测量提供了实用的工具,也为在运动技术诊断和分析中应用三维跟踪扫描影像分析方法奠定了基础。此外,还对控制点目标观测与坐标框架换算系统的需求、总体架构、数据库设计、算法设计、具体功能和应用实现等方面进行了较为详细的论述。

Direct Linear Transformation（DLT） is one of main algorithms used in 3D motion image analysis,moreover the spatial coordinates of control points are the fundamental parameters to calibrate the cameras using DLT algorithm,and are usually given by 3D calibration frame.Because of the limited room covered by 3D calibration frame,the error will occur when using 3D motion image analysis system to track and measure the moving object in the relative large range.The purpose of this study was to develop the software system to measure control points and transform coordinates using C# programming language with the total station（Topcon GPT-3002N）.This system can provide an applied tool to survey the accurate spatial coordinates of control points positioned as you wish in the large range,or fixed on the 3D calibration frame,and meet the needs to carry out 3D tracking motion image analysis in analyzing and diagnosing the techniques in sport movements.In addition,the demands of the system to measure control points and transform coordinates,general structure,design of database and algorithm,functions and realization in practice were describe in details in this paper.
