| 中文摘要: |
| 目的 获取物体在三维空间中的飞行着靶姿态。方法 提出一种基于2台高速相机双光轴交汇的测量方法，即利用2台相机同步拍摄，获得各自物体的姿态角度，根据相机光轴方位、相机与目标物体的空间位置关系，推导出物体着靶角的数学表达式，结合实际应用需求，获得几种特殊情形下的简化形式。结果 把该方法应用于跌落试验的实测分析，迅速且准确地获得了物体的着靶姿态。结论 该方法中相机的布置方式受试验场所的约束较小，可为跌落、高速撞击等异常安全性试验研究提供有效支撑。 |
| 英文摘要: |
| To obtain the target attitude of object in space, a measuring method was proposed through dual high-speed cameras with optical axis intersection The attitude angle of object was simultaneously recorded using both of high-speed cameras. Considering the space relations between the axis intersection angle and location of two cameras, the mathematic expression of the attitude angle of object was constructed. The simplified forms were given under several special cases. The method was employed to measure the impact angle of object in the drop tests. Using the proposed method, the accurate impact angle of object was measured. The current method has little restriction of the camera arrangement during the measurement process. The method may provide key support for research of the aberrant drop and high-speed impact. |
