Abstract
The research and development concerning the car will be actively done as of 2010. Today, backup that aims at low carbon society from existence of reduction movement of heat-trapping gas for global warming prevention expected that the number of introductions of hybrid car will increase in the future. Meanwhile, the hybrid car and electric vehicle confirmed that the situation that is not noticed the approach of these cars easily or not noticed at all happens because the sound is structurally small. Purpose of study is development of Haar-Like-Feature and the pattern detection by AdaBoost and the development of the device which used a parallax image by the stereo matching. That detects car of dorsal from pedestrian side and promotes collision avoidance. This reports on the effectiveness of the basic research and system.
