For mobile mapping systems with high accuracy demands, moving from standard stereo systems with their proven camera models, calibration procedures and measuring accuracies
This section describes a novel improvement of the geometric hashing algorithm. The probability of finding a correct match in the database is increased while decreasing the size of
After the determination of initial parameters of the asso- ciation potential and the parameters of the temporal association potentials in an initial training phase, an iterative
Combined with in-situ measurements, this paper presents models of city or local climate (air pollution and urban heat island), with a resolution of less than one kilometer,
In our experiments, the sub-pixel quantification is obtained by applying sparse repre- sentation using elementary spectra derived from (1) a manually designed spectral library, and
Our first con- tribution is to provide a fast segmentation technique for dense and sparse point clouds to extract full objects from the scene by lever- aging the implicit range
For our boundary representation, we assume that each vertex is defined by at least three planes intersecting in one point. Adja- cent faces lying in the same plane will therefore
Phase center clusters occur at light pole height steps (signal path: ground - light pole base; light pole base - pole) as well as on the pavement surface behind the light pole
