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.
