  • Lane-line recognizing apparatus for vehicle
    Patent number: 11887382
    Abstract: A lane-line recognizing apparatus for a vehicle includes an edge-point detector and an approximate-line calculation processor. The edge-point detector is configured to detect edge points on the basis of brightness variation within a detection region for a lane line. The approximate-line calculation processor is configured to calculate an approximate line of a point group including the edge points. The lane-line recognizing apparatus has: a first mode in which the lane-line recognizing apparatus is configured to mainly search for standard edge candidate points having brightness relatively high; and a second mode in which the lane-line recognizing apparatus is configured to mainly search for opposite edge candidate points having brightness relatively low. The lane-line recognizing apparatus is configured to selectively perform switching between the first and the second modes in accordance with the number of the detected opposite edge candidate points.
