Detektion von Fahrzeugen in Videosequenzen von luftgetragen thermischen Kameras
In this contribution we describe a method to assess the activity of vehicles 
in dense build-up areas. The analysis is based on airborne image sequences from 
an infrared camera. At the resolution of approximately one meter vehicles appear 
as elongated spots. They are extracted by a spot detector. In urban areas many 
additional other objects have the same property. To discriminate vehicles from 
these objects we fuse information about streets from digital maps an IR-images. 
Additionally, context knowledge is exploited by grouping of vehicles into rows 
along the margins of the roads. The generic productions for grouping are supported 
by using map knowledge as context again. Evidence from overlapping areas of frames 
of the IR-sequence is accumulated in the scene.
