Abstract
An in-vehicle front camera has come to be used a lot by a drive recorder, and a back camera is also popular. Then we propose a new method to detect following vehicles using these two cameras. A scene imaged by front camera will come out at back camera after a few seconds when a host vehicle is running. Therefore it is possible to detect following vehicles by comparing these front and back images. If we see the same road situation, it means no vehicle. If there is not the same object in the back image, there is a vehicle backward. To analyze these situations we use projective transformation. In this paper, we show details of our proposed method and validity by experiments in typical situations such as front and back vehicles, only front vehicle, only back vehicle and no vehicle in front and back.
