Convergence monitoring compares two Hovermap scans of the same area to identify and visualize physical changes over time, such as ground movement in underground tunnels or excavation progress between surveys. Aura aligns the scans, generates a reference mesh, and calculates point-to-mesh distances so the differences can be inspected with a colour-coded gradient.
The article in this section walks through the full workflow:
How to Process Scans for Convergence Monitoring. Configure a convergence monitoring job, manually align two scans, process them, and inspect the resulting point cloud and mesh.
