Optimize your geohazard resource allocation with with our 3D ICP lidar change detection

WATCH THE DEMO

Cambio lidar change detection enables reliable and cost-effective geohazard detection, monitoring, and analysis for large areas

Method 1: DoD

Time to detect: 12 years

Limit of detection (LOD): -0.60m to +0.65m

01

Digital Elevation Models (DEM) of Difference/DOD
This 2D view is common but insensitive [high limit of detection] producing results that can be hard to trust.

Method 2: 3D, no ICP

Time to detect: 8 years

Limit of detection (LOD): -0.40m to +0.55m

02

3D with No ICP Alignment

This 3D view provides some improvement in limit of detection.

Method 3: 3D ICP

Time to detect: 4 years

Limit of detection (LOD): -0.20m to +0.15m

03

3D with Iterative Closest Point
Using ICP reduces limit of detection by 3-5x, providing results you can confidently make decisions with and identify geohazards before they threaten the integrity of your asset.

Cambio’s 3D ICP lidar change detection provides

  • Earlier detection of new hazards (4 years vs 12 years with traditional methods)
  • Coverage of large areas at lower costs
  • Ability to identify hazards not visible in field visits
  • Detection of landslides that can stress pipelines over months/years/decades
  • Screen out sites that don’t need field visits
  • Analytics tools like advanced elevation profiles and change statistics to better understand the severity of geohazards
  • Additional contextualized datasets that can be layered on such as satellite imagery, precipitation, red relief, contours, hill-shading, and slope gradient to help visualize a more comprehensive picture.

In the Cambio platform, view your LCD data in context with your other sources, including instrumentation data.
