Vision-based vehicles in Japan: The machine vision systems and driving control systems

Tsugawa, S.

The configuration, machine vision systems and driving control systems of three intelligent vehicles developed in Japan are reviewed and the significance is discussed in automobile traffic of the future. The Intelligent Vehicle developed since the mid 1970' at MIPI has a machine vision system for obstacle detection and an autonomons navigation system based on dead reckoning on a compact car. The machine vision system is featured by real-time processing using hard-wired logic. The Personal Vehicle System (PVS), developed in the late 1980's by Fujitsu and Nissan, is a comprehensive test system for a vision-based vehicle. The machine vision system captures lane markings at both road edges for lateral control. The PVS has another machine vision system for obstacle detection. An intelligent automobile, named the Automated Highway Vehicle System (AHVS), developed by Toyota is capable of lane-keeping using machine vision. The three vehicles drove at 10 - 60 km/h. Possibility of solution of automobile traffic problems such as traffic accidents, congestions, and pollution using intelligent vehicles is discussed.
