This video is about automatically calculating bridge clearance on large scale pointcloud.
From raw input pointcloud, get individual minimum height value under each bridge featured in the pointcloud
Step by step
Load your raw RGB mobile mapping pointcloud and optimize to OPC format if needed
Classify Roads and Bridges and extract Bridges as 3D-Objects
Set in Extract > AI-Detection and set in a New Project
Select your pointcloud
3D-Segmentation

Start
Create bridges' footprints
Set in Tools > Create footprints
Extract bridges footprints (See documentation)
Calculate bridge clearance for each bridge
Set in Extract > Clearance Checker and Set in a New Project
Select your raw RGB pointcloud
Method: Multiple Areas and select the footprints you previously extracted
Define settings as per your needs (see documentation) and and Start
Output
The output of this work is individual points
For each bridge: 1 point + minimal clearance available as an attribute that can be shared or exported to any GIS format
