Modelling of waste water pipe network by using Hand held Lidar scanner point cloud data

SBL was recently awarded a waste water pipe modelling project from a handheld scanner point cloud data by a global firm of 3D scanner manufacturers and retailers from the UK.

A section of sewer pipe network and its connections (refer Figure 1 above) was modelled with the help of point cloud data from a hand-held scanner. A major challenge in the project was that the input point cloud data was provided without RGB values since the LiDAR survey was carried inside a pipe where there is no light.
SBL carried out the detailed mapping from the LiDAR point cloud data using “as is”, rule without generalizing or offsetting any feature. Cross section views were used to capture the data to the highest possible accuracy wherever changes occur in terms of shape and size.
Check out the images below which depict graphically the level of expertise and care that was taken by the team at SBL to execute the project.

This project marks another achievement by SBL in the LiDAR modelling domain. We are expecting to showcase few more such projects in our upcoming blogs.
