Abstract

Many Of The Fatalities And Injuries In The Construction Industry Occur In Scaffolding Accidents, And Monitoring The Scaffolding Process And Checking Compliance Are Critical. However, Monitoring Scaffolds Is Labor-Intensive And Inefficient Because It Is Done Manually. To Address This Issue, We Propose An Advanced 3D Reconstruction Method For Detecting And Monitoring Scaffolds. Deep Learning-Based RandLA-Net Architecture Is Used To Perform Scene Segmentation. RandLA-Net Is Trained Based On Transfer Learning, Using The Knowledge Of The Model Learned With The Semantic3D Dataset. RandLA-Net Uses 3D Point Cloud Data That Are Matched And Registered By LIO-SAM, A Laser Slam Algorithm. By Attaching A LiDAR To A Quadruped Robot, It Is Possible To Obtain Data Frequently In A Manner Suitable For Construction Sites. The Proposed Methodology Has Demonstrated Good Performance In Monitoring Scaffolds.
