Survey Control Targeting in Dot3D

Reference targets allow you to improve the accuracy of your scan by using known target positions during optimization. This can be used when working with larger areas, or simply whenever you have convenient coordinate data for tags.

Make sure your targets are distributed around the perimeter of your scan area for greatest effect.

Coordinates can be obtained from a surveying total station, a GNSS or RTK receiver, another laser scan, a drone, an existing survey map of the space, or an existing 2d or 3d cad model. This information needs to be obtained and imported into Dot3D.
