Change detection
and AI screening

The data tells you what changed

These are the common cases. Ask us about calculating sediment volume and earthwork volume, ongoing monitoring of change over time, or any analysis shaped around what you need to know.

When to talk to us

• You want to quantify deterioration and deformation.
• You're worried that visual inspections alone will miss something.
• You want to compare an earlier point cloud with the site as it is today.
• You want a record of what changed before and after construction or renovation work.
• You have a lot to inspect and need to decide what comes first.
• You want early warning of settlement or displacement.

How change detection works

1. Initial discussion and data review

   We go over your goal and the target area. If you already have point cloud data, bring it. We quote each job based on what it involves.

2. Scanning and registration

   If you don't have a baseline dataset, we start with a 3D laser scanning survey. We then register both point clouds into the same coordinate system.

3. Change detection and AI screening

   We extract the changed areas and narrow them down to the locations that need a closer look.

4. Reports delivered

   We deliver a heat map and a list of the locations that need a closer look, organized into a form you can act on.

Deliverables

• Analysis report

  A report (PDF) covering what changed, the numbers, and our findings. You can use it as is for internal reporting and repair planning.

• Point cloud data with changes highlighted

  Point cloud data with the amount of change color-coded as a heat map. E57, LAS, and other formats on request.

• Sharing through TENZOH

  We deliver the analysis results through TENZOH, our point cloud viewer. Everyone involved can open it in a browser. Nothing to install.

Note: Ask us about ongoing monitoring as well (scheduled scans and comparison from the same fixed points).

Frequently asked questions

Can you compare against point cloud data from an earlier scan?

Yes. Send us the older data you already have, and we take it from registration onward. If you don't have a baseline dataset, talk to us about starting from the first scan.

What can change detection tell you?

Displacement, deformation, and sediment buildup are changes the eye misses. We can show them as numbers and a heat map, which gives you a factual basis for inspection and maintenance decisions.

What form do the analysis results come in?

An analysis report (PDF) and point cloud data with the detected changes displayed. We can also share the results in a browser through TENZOH, our point cloud viewer.

What does it cost?

We quote each project based on scope and the analysis involved. Start with a message.
