Abstract
System that enables colorization and color adjustments on 3D point clouds. Point clouds are projected onto a 2D view, for example with an equirectangular projection. A user may color regions on the 2D view, and preview the changes immediately in a 3D view of the point cloud without a time-consuming update of the point cloud data. Because any 2D projection introduces distortions, 3D preview is important for the user to observe the effects of the color changes on the point cloud. Embodiments may for example render the color of each point in the point cloud by testing whether the 2D projection of the point is inside the colored region. Alternatively, the region may be triangulated, and a GPU may render a texture image and use this texture to render the 3D view. Applications may include generation of a color 3D virtual reality environment using point clouds and color-adjusted imagery.
