The second station (CultArm3D) serves the refinement of the first scan. Selectively, either a structured light scanner or another camera with a ring light records the artifacts’ geometry and texture. When combined with CultArc3D, CultArm3D is used to capture remaining holes, occlusions or geometrically complex surface areas in more detail. For this, an iterative plan for scanning with the CultArm3D is calculated based on the results of the first station. In this way, occlusions and possible gaps in the first 3D model can be eliminated with a targeted approach to the missing view angles.
The use of a camera with a ring light attached to CultArm3D allows for the fully automatic digitization of an artifact on a turntable.
