Abstract
Described herein are methods and systems for texturing a three-dimensional (3D) model using photogrammetry. A sensor captures scans of a physical object, including related pose information, and color images corresponding to each scan. A computing device generates a 3D mesh of the physical object. The computing device preprocesses the color images to remove blurry images and detect textured regions of the object in each non-blurry image. The computing device optimizes the pose information for each color image by generating associations between the color images and vertices in the 3D mesh and classifying the vertices as textured or non-textured. The computing device generates texture coordinates for the 3D mesh by segmenting the mesh, parameterizing the segments, and packing the parameterized segments into a texture atlas. The computing device paint the texture atlas using the color images that have optimized pose information to generate a model having texture coordinates for each vertex.
