Abstract
Examples relate to three-dimensional (3D) scan tuning. In some examples, preliminary scan data is obtained while the real-world object is continuously rotated in view of a 3D scanning device, where the 3D scanning device performs a prescan to collect the preliminary scan data. The preliminary scan data is then used to determine physical characteristics of the real-world object, and a camera operating mode of the 3D scanning device is modified based on the physical characteristics. At this stage, 3D scan data for generating a 3D model of the real-world object is obtained, where the 3D scanning device scans the real-world object according to the camera operating mode.
