Verifying the accuracy specifications of NavVis VLX 3

White paper
September 2024

In this document, NavVis demonstrates a rigorous, reliable, and survey-based method for verifying the accuracy of point clouds produced by a dynamic laser scanning system.

Dynamic laser scanning systems have become an essential part of the survey and documentation toolbox thanks to benefits such as faster workflows, easy capture of panoramic imagery, photorealistic point clouds, and automated processing.

But there is still one major roadblock to wider adoption: The 3D-capture industry has not established a standardized method for estimating or verifying the accuracy of a dynamic laser scanning systems system. As such, professionals who require high-accuracy deliverables can find it challenging to trust stated accuracy specifications – making it difficult to know whether a mobile mapping system is appropriate for their current project.

In this document, NavVis will address this problem by demonstrating a rigorous, reliable, and survey-based method for verifying the accuracy of point clouds produced by a dynamic laser scanning system.
