A forward direction monitoring device has a camera to take an image of road condition in front and a back-projection image is generated. A radar part receives reflected waves from objects in front and obtains their relative position data. These relative positions are mapped on the image taken by the camera. Portions of the image are specified with reference to these relative positions and brightness distribution of image portions is analyzed to distinguish the kinds of the objects. After those of the relative position data not related to a desired object are eliminated, the remaining relative position data are obtained sequentially to monitor the desired object based on the obtained data. |
