<p>PROBLEM TO BE SOLVED: To provide a driving lane detection device capable of improving the detection accuracy of a zebra zone.SOLUTION: A driving lane detection device includes: an imaging part 21 for imaging a driving lane on which own vehicle travels; line detection parts 11, 12, 13, and 14 for detecting a white line or a yellow line on the driving lane based on brightness information of a photographic image P imaged by the imaging part 21; and a zebra zone detection part 16 sandwiched by a plurality of white lines or yellow lines detected by the line detection parts 11, 12, 13, and 14 and detecting a region having brightness equal to or more than a preset threshold value as a stripe-shape region. A zebra zone Z is a region sandwiched by the plurality of white lines or yellow lines, and is the stripe-shape region within which the white lines or the yellow lines are coated in a stripe-shape manner. Therefore, the detection accuracy of the zebra zone Z can be improved by detecting the region having brightness equal to or more than the preset threshold value as the stripe-shape region.</p> |
