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.
