Accuracy Assessment of Vegetation Height Mapping Using Spaceborne Ikonos as well as Aerial UltraCam Stereo Images

High resolution space-borne remote sensing image data show a high level of detail and provide manifold opportunities to be integrated into remote sensing applications. In particular, surface mapping from stereo data sets becomes feasible with a height accuracy in the meter range. Following the focus on forest applications of the Institute, the feasibility to determine tree heights from high res...

Photo-realistic 3d Mapping from Aerial Oblique Imagery

The generation of photo-realistic city model is an important task for many geospatial applications, such as 3D GIS, urban planning, virtual city tourism, car navigation, real estate, etc. The purpose of this research is to automatically generate façade texture from aerial oblique imagery. The developed algorithm can be applied to any oblique imagery taken from the air, such as UAV, airplane, or...

High resolution terrain mapping using low altitude aerial stereo imagery

This paper presents an approach to build high resolution digital elevation maps from a sequence of unregistered low altitude stereovision image pairs. The approach first uses a visual motion estimation algorithm that determines the 3D motions of the cameras between consecutive acquisitions, on the basis of visually detected and matched environment features. An extended Kalman filter then estima...
