Nowadays, many vehicles are equipped with a vehicle borne camera system for monitoring drivers' behavior, accident investigation, road environment assessment, and vehicle safety design. Huge amount of video data is being recorded daily. Analyzing and interpreting these data in an efficient way has become a non-trivial task. As an index of video for quick browsing, this work maps the video into a temporal image of reduced dimension with as much intrinsic information as possible observed on the road. The perspective projection video is converted to a top-view temporal profile that has precise time, motion, and event information during the vehicle driving. Then, we attempt to interpret dynamic events and environment around the vehicle in such a continuous and compact temporal profile. The reduced dimension of the temporal profile allows us to browse the video intuitively and efficiently.
