Abstract: This paper presents a method for real-time vehicle shape classification based on its side outline. It extracts the background dynamically, through the trigger of soft sensor, gets the silhouette of the vehicle from the difference between current frame and background frame and reaches the vehicle shape classifier based on side outline character. Compared with the other approach, it shows a higher efficiency and accuracy, which enables the excellent application in the real-time system.

Key words: intelligent transportation, soft sensor, vehicle classification, real-time
