A 3D Model of Castle Landenberg (CH) from Combined Photogrammetric Processing of Terrestrial and UAV based Images

In this paper we demonstrate the workflow of 3D modelling and photorealistic texture mapping based on close range imagery acquired with a mini-UAV (Unmanned Aerial Vehicle) and in terrestrial mode. For generation of a highly accurate 3D model, a combined photogrammetric processing of these images was required. The conducted workflow consists of the following steps: project planning, flight planning, terrestrial and aerial image acquisition, camera calibration, control point measurement using GNSS (Global Navigation Satellite System), measurement of control and tie points in the images using the photogrammetric close rangeprocessing software Photomodeler 6, modelling and texturing of the object and visualization of the finalized model. Finally we achieved an excellent high resolution textured 3D-Model of the castle Landenberg with combining terrestrial- and UAV-Photogrammetry.
