Traffic surveillance | ||
The intended operational environment is over an area with widely varying geographical terrain containing traffic networks in city, suburban and rural areas, which may be both densely and sparsely populated by vehicles ranging from passenger cars to tractor-trailers.
The UAV's "understanding" of the environment is dictated by its sensory capabilities and by the major tasks that are defined for it. They are:
One important basic processing step is to find moving objects in the scene. This can be a challenging task due to camera motion etc. The video clip shows a stabilized road scene to the left. Motion blobs has been detected via spatio-temporal filtering (right). These motion blobs contains information of motion velocity and direction, and can be used as input to a object tracking algorithm. From the motion information of the individual vehicles, information about the road network, etc, it is possible to implement the tasks described above. |
