CAESAR is a multispectral scanner jointly developed by the Nationaal Lucht- en Ruimtevaartlaboratorium (National Aerospace Laboratory) and Technisch-Physische Dienst. First, the ' CAESAR-images are geometrically corrected by the software-package OPTIPARES, using inertial system data and a geometrical analysis is performed. These images are then used in an automatic procedure to calculate the geometrical transformation-model between these images. This is done in order to use the spectral information as good as possible. Correlation-techniques are used within this procedure. By using two images, in the first image interesting points are found by using the Moravec-operator. The corresponding points in the second image are determined by a ~2D-cross-correlation. From the -two point-lists the geometrical transformation-model can be calculated. In the opinion of the NLR, a shift is sufficient in this model. The results show that this assumption can not hold. Higher-order polynomals give better results. When the geometrical transformation-model is known, a resampling takes place to match the images To reference this document use: http://resolver.tudelft.nl/uuid:5fe74425-a747-4600-8e3a-ad142ab33f58 Part of collection Student theses Document type master thesis Rights (c) 1988 W.J.
