TeleSculptor is a cross-platform desktop application for photogrammetry. It was designed specifically with a focus on aerial video processing leveraging video metadata standards for geolocation, but it can handle both images and video either with or without metadata. TeleSculptor uses structure-from-motion techniques to estimate camera parameters and a sparse set of 3D landmarks. TeleSculptor also estimates dense depth maps on key frames using multiview stereo techniques. It then fuses those depth maps into a consistent surface mesh, which can be colored from the source imagery. TeleSculptor’s flexible plugin architecture allows developers to reconfigure or swap out any algorithm in the pipeline for custom implementations. It is both an end-user application and a research platform.
