Automatic Estimation of Vehicle Activity from Airborne Thermal Infrared Video of Urban Areas by Trajectory Classification

Extraction and motion estimation of vehicles in single-pass airborne LiDAR data towards urban traffic analysis

“…Traffic monitoring remains as one of the few fields which are still not as intensively analyzed in the LiDAR community compared to other modern sensor techniques such as frame and linear optical cameras (Zhao and Nevatia, 2003;Eikvil et al, 2009;Hinz et al, 2008;Larsen et al, 2009), Synthetic Aperture Radar (SAR) (Meyer et al, 2006;Bethke et al, 2006), and infrared (IR) cameras (Kirchhof and Stilla, 2006;Yao et al, 2009). The most relevant research to our work came from Toth and Grejner-Brzezinska (2006).…”
