Mesh Conflation of Oblique Photogrammetric Models Using Virtual Cameras and Truncated Signed Distance Field

Truncated Signed Distance Fields

This thesis is concerned with topics related to dense mapping of large scale three-dimensional spaces. In particular, the motivating scenario of this work is one in which a mobile robot with limited computational resources explores an unknown environment using a depth-camera. To this end, low-level topics such as sensor noise, map representation, interpolation, bit-rates, compression are invest...

Biomass Estimation Using Digital Photogrammetric Cameras

Estimating and modelling biomass can be helpful for biomass management. It is also interesting to calculate the amount of biomass in a certain area for carbon implications, as indicated by the Kyoto protocol. In the past remote sensing techniques have been able to estimate biomass by using reflectance in the both the red and the near infrared wavelengths. Nowadays the sensors in the digital pho...

Photogrammetric Techniques for Panoramic Cameras

Panoramic cameras are used in aerial surveillance for the rapid coverage of large areas of terrain. Different Panoramic camera designs vary substantially, so that there is no such thing as a generic panoramic camera similar in generality to the pinhole model of a frame camera. This is true for instance for methods of forward motion compensation for which different methods are used. Nevertheless...

UltraCam Photogrammetric Digital Aerial Cameras

Digital photogrammetric cameras: possibilities and problems

Airborne digital sensors are about to widen the choices in photogrammetry. The transition from analytical to digital photogrammetry is well advanced and the dividing lines between photogrammetry and remote sensing grow increasingly blurred. One of the advantages of direct digital data capture in the air is the possibility of capturing multispectral data as well as panchromatic. Positioned betwe...
