This paper presents a method for automatically generating large-scale road-network vector maps, based on GPS-probe-vehicle tracks. This method does not need to employ the basic maps of road-network maps, but only to use the tracks that are formed when GPS probe vehicles are moving in road networks, to reflect the real topology of road networks onto digital maps automatically. The proposed method consists...
This paper presents a real-time algorithm for detecting and tracking bicyclists or pedestrians using a laser device. By processing the sequence of the range images, the algorithm outputs trajectory and speed of each object during the period when he is in the detection region. The whole algorithm consists of two parts, which are the object detection and the object tracking. In the former, the multi-level...
