摘要
介绍了对泥石流实验实施近景摄影测量的情况 ,以泥石流实验中由两台相机对泥石流连续同步拍摄的立体像对作为量测介质 ,采用数字摄影测量技术或测图仪观测泥石流表面特征点三维坐标 ,通过建立泥石流三维立体模型获得泥石流运动动态过程及系列参数。三维坐标量测精度约为± 4mm。
This paper describes the method and results of close range photogrammetry for a debris flow experiment.Two cameras were used to take the stereopair of debris flow continuously.The 3D coordinates of feature points in the surface were collected by digital photogrammetric technique in an accuracy of about±4mm.The dynamic movement process and parameters of debris flow were also derived from a 3D model.
