Abstract
The disclosure describes systems and methods of selecting colors to points in a digital three-dimensional (3D) model representing a scanned object, based on points and color images associated with the 3D model. Certain embodiments involve selecting from the images a patch for each point in the 3D model, and determining a quality of the patches. The selected patches are analyzed to determine an overall score, representing aggregated quality of the patches and an aggregated smoothness indicating variation between patches selected for neighboring points. In some examples, multiple sets of selected patches are analyzed and scored, and the scores are compared to determine a representative patch set that optimizes the quality and the smoothness. Colors are assigned to the points of the digital model based on the representative set of patches.
