RMSE (Root Mean Square Error)
RMSE is a statistical measure of the average distance between corresponding points in two datasets, used in scanning to quantify how well a registration fits its control network.
A lower registration RMSE means the point cloud is more tightly anchored to the real-world control points — on our projects, registration RMSE typically stays at or below 3 mm against the Total Station network.
Where this is used
Frequently asked
Do I need to understand RMSE (Root Mean Square Error) myself, or is that your job?
That's on our side — RMSE (Root Mean Square Error) is part of the standard capture methodology built into every project; this entry exists so you can follow a technical conversation, not so you have to run the process yourself.
Does RMSE (Root Mean Square Error) change how a project is priced?
No — RMSE (Root Mean Square Error) is a standard part of the capture workflow included in every quote, not a separate paid add-on.
Is RMSE (Root Mean Square Error) specific to your workflow, or standard across the industry?
Standard across the laser-scanning and surveying industry — we apply RMSE (Root Mean Square Error) the same way any competent provider would, not as a house-specific method.
How would I notice if RMSE (Root Mean Square Error) wasn't done properly on a project?
It shows up downstream, in a drawing or model that doesn't match reality on-site — which is exactly why it's built into every project rather than treated as optional.
Can I ask more about how RMSE (Root Mean Square Error) applies to my specific project?
Yes — send a question through the Contact page; a specific question about RMSE (Root Mean Square Error) on your project is a normal thing to bring to a scoping call.
