Estimation of vehicle movement in urban areas from thermal video sequences

In this contribution we describe a method to assess the activity ofvehicles based on airborne image sequences taken by an infrared camera.At the resolution of approximately one-meter vehicles appear as elongatedspots. Active vehicles often appear as a configuration of a darkand a bright spot close to each other, where the latter results fromthe warm motor hood. For the estimation of vehicle movement a precisemeasurement of the sensor movement is required. The sensor movementis inferred from image sequences. A robust estimation avoids outliersin the set of point correspondences. A special selection strategyprefers samples that promise estimation precision.     «
