Driving support system using image recognition for physically-handicapped person

摘要

This paper proposes a method of detecting the ground floor in hallway for electric wheelchair. And we also propose a method of measuring the distance between the ostacle and wheelchair and obstacle width by using single monochromatic camera and a supersonic sensor. The algorithm detecting ground floor is based on the assumption that the ground floor doesn't have any remarkable pattern. We use edged images to detect borderline between the ground floor plane and the obstacle. Then we could obtain good results in real environment using this simple image processing method. And we show the result of measured obstacle width.
