Application of LiDAR and BIM Technology in Tunnel Disease Detection
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.
