PURPOSE: To extract traffic edges certainly and stably to a distance by transforming a picture in which vehicle proceeding direction is picked up to the picture which is viewed from another point of view and recognizing the positions of the traffic lane edges from the converted picture.
CONSTITUTION: The picture of the front side of a vehicle 1, which is picked up by a TV camera 3, is converted to a digital signal by an A/D converter 5 and stored in a picture memory 7 as a picture date. The picture data stored in the picture memory 7 is supplied to a view-point converting processing part 9 in which the picture data is converted to the picture which is viewed from just above a road and processed by a filtering arithmetic part 11 in order to output the apparent traffic lane edge and supplied to a template forming part 13 in which one traffic lane edge is extracted. This extracted template is sup plied to a matching processing part 15 in which entire traffic lane edges are extracted. The relative position relation between the vehicle and the traffic lane edge is judged by a relative position judging part 17 and a warning is sent out of a warning outputting part 19 when the position relation between both of them is abnormal.
