影像三维激光扫描测量技术在风沙地貌台风响应模式中的应用研究
|
摘要
影像三维激光扫面测量是目前前沿的监测技术之一。在阐述影像三维激光扫描测量的原理及在分析其理论测量误差的基础上,采用影像三维激光扫描技术于2014年至2017年实地对福建平潭岛百犬山海岸地貌进行了21次观测,分析结果表明:影像三维激光扫描技术与传统的风沙地貌台风响应监测相比具有速度快、精度高、能实时测量出其变化量等优点,在风沙地貌响应监测中具有广泛的应用前景。
Image 3d laser scanning measurement, is currently one of the frontier monitoring technology. Based on the principle of image 3d laser scanning measurement and its theoretical measurement error analysis, the paper conducted 21 observations on the coastal landscape of Baiyingshan, Pingtan Island, Fujian from 2014 to 2017 by using the image 3D laser scanning technology. The analysis results show that comparing with traditional sand physiognomy typhoon response monitoring, the image 3d laser scanning technology has the advantages of fast speed, high precision, real time measurement of its variation, which has broad application prospects in aeolian landform response monitoring
