In the above link there is a metric & imperial version. Both have sample data inside of them that you will need to delete before using your own data.

Video Description:

Unlock the secrets to accurately measuring point cloud accuracy in 3D scanning with the innovative One-Dimensional Method! If you work in land surveying, construction, or reality capture and struggle with unreliable accuracy metrics from registration software, this video is for you. Learn how to leverage survey control for more reliable, efficient, and transparent point cloud accuracy assessments-perfect for projects using LiDAR, photogrammetry, or SLAM.

In this step-by-step guide, we’ll compare traditional accuracy measurement workflows with a new, streamlined approach that:

Reduces field and office time
Increases the density and flexibility of check shots
Eliminates the need for excessive physical targets
Avoids the pitfalls of manual digitization errors

You’ll see practical demonstrations using tools like total stations, N4ce, and CloudCompare. Discover how to:

Set and code check shots efficiently
Use perpendicular surfaces for optimal results
Extract and compare 1D distance vectors between point cloud and control data
Visually inspect and validate your point cloud for blunders and errors

Download the FREE accuracy reporting workbook to automate your analysis with graphs, scatter plots, histograms, and more!

Whether you’re a surveyor, BIM specialist, or point cloud technician, mastering this method will help you deliver more reliable data to your clients and reduce costly mistakes.
