数字近景摄影测量在模型试验平面位移场测量中的应用

Application of Digital Close Range Photogrammetry for Monitoring 2D Displacement Field of Model Experiment

模型试验中常用物理或机械的方法测量位移场 ,该文利用数字近景摄影测量方法对高速公路边坡滑移物理试验模型的位移场进行测量 ,并对用简化的单像平面处理方法与立体解算方法的试验结果进行了比较。试验结果表明 ,利用数字近景摄影测量位移场的方法简单、精度较高 ,可用于亚毫米级精度的位移测量。

Digital close range photogrammetry method is employed on model experiment of slope sliding displacement field measuring with different obliquity,to dispose planar displace monitoring, stereo computing and a simplified 2D method are introduced and made a comparison here. The result showes that the simplified 2D model is more convenient and with higher precision.
