激光扫描技术在路面病害检测中的应用

通过分析目前3D激光扫描技术在测量领域的应用现状，介绍加拿大ILRIS-3D激光扫描系统的硬件设备的特点、数据处理软件PolyWorks的功能和操作方法，探讨ILRIS-3D在路面平整度及病害检测中应用的可能性，同时通过路面试验证明：ILRIS-3D扫描得到的数据经Poly Works处理后，能较好地反映原始的路面特征，并能给出相应的路面病害数据，说明利用激光检测技术进行路面病害特征检查是一种先进的手段。

Application of Laser Scanner System in Pavement Inspection

The application actualities of the 3D laser scanner technology have been analyzed in the measurement area, so are the characteristic of equipment, functions and manipulation methods of PolyWorks using in data processing introduced. What＇s more, the technicians have tried to probe into the possibility of detecting the pavement smoothness and disease with the ILRIS-3D. Pavement test has proved that data gained in ILRIS-3D can comparatively reflect the original road surface characteristic and provide the surface data corresponded with the fact after being manipulated through PolyWorks. h shows that it is an advanced method for pavement inspection using the laser detection technology.
