摘要
利用激光扫描仪与导航POS组成的车载三维测量系统对立交桥的各层路面进行移动平推式扫描,获取立交桥的三维信息.将导航POS获取的系统位置与姿态信息和激光测距仪获取的扫描距离与角度信息进行时间匹配,通过解算得到大地坐标下的三维激光点云坐标.同时,可以利用定点的三维旋转式激光扫描,获取立交桥的横断面信息及交错处的内部细节.在实际应用中,针对立交桥这一特殊城市道路建筑进行测量,取得了一定的效果.
This paper presents a vehicle-borne 3D laser scanning system with the laser sensor and POS, which is designed for 3D mobile scanning the whole roads of interchange. To attain the 3D laser points cloud on the Geodetic coordinate for combining the location and stance information from the POS with the range and angle information from the laser sensor on the homologous time. Furthermore, with the 3D rotate laser scanning on the certain location, the transect information and the detail of the interchange can be obtained. In practice, as a special architecture on the roads, interchange survey has been achieved some rsuhs.
