摘　　要：通过对大客车前风窗检具及主控空间曲线特点的分析，探讨了测量检具的方法，进一步分析了各种测量误差。提出了“分段测量法”和“触点坐标调整法”，并采用了“一元三点插值”的误差分析方法。与CAD接口的编程技术减少了数据处理工作量，提高了数据处理效率。数据处理结果表明，该检具具有足够的精度。By analysis of inspection gauge of bus windshield and dominant Space curve characteristic, method of inspection gauge measurement is probed into and then different measurement errors are further analyzed. 'Segment by segment measurement method' and 'Probe touch point coordinate adjustment method' are recommended for the former, and'Single element three point interpolation' error analysis method adopted for the latter. The program compiling techniquewith CAD interfacing reduces data processing volume and promotes data processing efficiency. Result of data Processingproves that the inspection gauge has quite high accuracy.
