Vehicle Extraction Using Geometrical Constraint

Abstract

In recent years, with the popularization of vehicles, road traffic has tended to increase. Therefore, it is important to rapidly collect road traffic information. In this study, we propose a method of determining the position and movement of vehicles and a method of showing the overhead view using images taken at an intersection from the oblique view with only one video camera. In this method, we use the vehicle shape model and determine the position of the model by the simple computation using the vanishing points and the vanishing line obtaining from the geometrical projection between the image and the road plane. Then, we project the position information onto the digital map, and we show the overhead view of the vehicle position in each frame of the image.
