| 摘 要： | 碰撞试验是综合评价汽车碰撞安全性能的最基本、最有效的方法。定标墙是碰撞车辆变形测量分析系统(DMAS)重要的组成部分,是由10万多个编码点和标识点组成的一种测量空间网络,为测量系统提供标准值,从而获得汽车车身的形变。本文提出了一种汽车碰撞试验定标墙的现场校准方法,利用摄影测量系统与标准尺,通过合理布局实现定标墙的高精度校准,用该方法可将定标墙的标识点的坐标校准误差控制在0.05 mm。

| Abstract: | Crash-test is the most basic and effective method of comprehensive evaluation on automobile security performance. Reference wall is one of the most important elements in the Deformation Measurement and Analysis System (DMAS), which is composed of more than 100,000 codes and targets, and provides standard value for the system to get automobile body deformation volume. A field calibration method for the reference wall of crash-test was presented in this paper, which improves the precision of calibration through proper redistribution by using photogrammetric system and scale bar, and the RMS is 0.05mm. |
