Acquisition of position and direction of in-vehicle camera for HIR system

In ITS development, it is expected that infrastructure maintenance of cameras or various sensors is carried out. For a system using those infrastructure, we have proposed the HIR (human-oriented information restructuring) System. This system assists driver´s visual sense by integrating and restructuring different kinds of information. This paper contributes HIR algorithm, error of data, and required accuracy towards realization of HIR System. Furthermore, we built the system to acquire position and direction of in-vehicle camera. Based on their previous study, we test the effectiveness of our developed system architecture and made experiment in the situation of turning right at the actual intersection, not georama. As a result, we can generate visual assistant images and display them on the car monitor in real-time.
