Abstract

The aim of this project was the extension of the functional range of an existing library used for labeling. Labeling in this context refers to the problem of texturing a mesh of an archaeological item, given a huge set of photos such that there is a vast amount of possibilities to choose a suitable photo for each triangle.

The first step was the implementation of a masking-feature. This feature is necessary, since not all regions in the photos are equivalently suited to texture the mesh. The masks are provided by the user of the library and show the regions in the photos that can be used for texturing of the model.

The second step was the implementation of an interacitve brushing tool. This brushing tool enables the user to enlarge the region that is textured by a particular photo (growing brush), or to replace the current photo that is used for texturing of a particular region with the photo, which is the next optimal photo suitable for texturing. The brushing tool was implemented into Scanopy, a point cloud editor that is developed at the institute.
