| Project description |
The thermal city inventory has three objectives: (1)
thermal acquisition of all objects of a city with a high
spatial resolution, (2) integration of the recorded spectral
image data into a three-dimensional city model, and (3) the
analysis of thermal surface data for detecting and locating
leaks, cracks and heat bridges. An information system is used
to manage the city model which is enriched by thermal
information. This allows for spatial queries of the data and
provides detailed information on heat loss of individual parts
of a building, e.g. of the roof and building facades. This can
be used to derive quantitative information on potential energy
saving of a building. The very stable flight condition of the
Gyrocopter at low speed allows the full coverage capture of an
urban region with TIR and SWIR frame cameras with a geometrical
resolution 10 to 20 cm. The project will develop methodologies
and procedures for thermal city inventory. This includes
georeferencing of the thermal images, the radiometric
calibration of thermal images (atmospheric correction,
conversion of radiances into temperature values), the
projection of images onto CAD models of buildings, derivation
of the surface temperature distribution of the different parts
of the building, the analysis for localising leakages and the
integration of all data in a database. |
