A lane detection sensor (K1) for detecting opposite lane markers of a road, comprising: an image shooting member (1) for shooting an image of the road ahead of a running motor vehicle; an image data memory (2) for storing data on the image of the road from the image shooting member (1); a contour point extracting member (3) for extracting, by using the data on the image of the road stored in the image data memory (2), contour points corresponding to the lane markers of the road; a curve detecting member (4) for calculating polynomial curves by using the contour points corresponding to the lane markers of the road from the contour point extracting member (3); a Hough transformation limiting member (5) for bounding a region of Hough transformation by using coefficients of the polynomial curves calculated by the curve detecting member (4); a Hough transformation member (6) for performing Hough transformation by using the polynomial curves from the curve detecting member (4) and the region of Hough transformation bounded by the Hough transformation limiting member (5); and a Hough transformation detecting member (7) which obtains a maximum value of accumulators in Hough space so as to detect a curve corresponding to the maximum value of the accumulators.
