Application of LiDAR and BIM Technology in Tunnel Disease Detection

隧道病害检测工作中以人工形式获取信息操作难度大,不仅影响测绘准确度,而且工作效率低下,针对这些问题,文章提出合理应用激光雷达扫描技术,通过多种方式获取隧道数据信息,并结合BIM技术将信息数据整合后统一到三维模型中来进行隧道的病害检测工作的方法。两种方法的结合提高了隧道病害检测的速度和数字影像数据的准确度,同时隧道病害检测时效性不足的问题也可得到解决,工作的效率得到了很大的提升。通过结合激光雷达技术的精确数据采集和BIM技术对现实环境可视化展现的优势,实现了对隧道病害的准确高效检测,可以更加直观地了解到隧道的病害状况。

The operation of manual information acquisition form is difficult in tunnel disease detection work,which not only affects the accuracy of mapping,but also has low working efficiency.In view of these issues,this paper puts forward a method that applies LiDAR scanning technology reasonably,obtains tunnel data information through a variety of ways,and combines with BIM technology to integrate and unify the information data into the three-dimensional model to carry out the tunnel disease detection work.The combination of the two methods improves the speed of tunnel disease detection and the accuracy of digital image data.At the same time,the problem of lack of timeliness of tunnel disease detection can be solved,and the working efficiency has been greatly improved.By combining the accurate data acquisition of LiDAR technology and the visualization advantages of BIM technology for the real environment,the accurate and efficient detection of tunnel disease is realized,and the disease condition of the tunnel could be more intuitively understood.
