摘要： An image processing system and the like capable of recognizing a lane mark in a road image with high accuracy are provided even if a light illumination state on a road surface is partially different. According to the image processing system (100) mounted on a vehicle (10), a color component (Rij, Gij, Bij) of the first pixel (Pij) included in an area (Aij) set in the road image is corrected with reference to a color component (Rik, Gik, Bik) of a second pixel (Pik) in view of a fact that it is highly probable that the color component of the second pixel included in the area along with the first pixel is affected by a shadow or light on the road surface. This reduces the effect of the shadow or light on the road surface and the actual color of a road surface portion corresponding to the first pixel can be sufficiently reflected in the color components (Rij, Gij, Bij) of the first pixel (Pij) and consequently in a feature value (Qij). Therefore, a lane mark (M) and its edge (E) are recognized in the road image on the basis of the feature value (Qij) of each pixel (Pij) in the road image.

摘要： An image processing system and the like capable of accurately recognizing lane edges defined by dotted lane marks are provided. According to an image processing system (100) of the present invention, a first processing unit (110) searches a road surface image captured by a vehicle-mounted camera for a “small area,” which is composed of high- or low-luminance pixels and satisfies “eligibility conditions” on the “size,” “shape,” and “arrangement” in the road surface image. Additionally, a second processing unit (120) recognizes “lane edges” of the lane along which the vehicle travels on the basis of the “small area.” Furthermore, a third processing unit (130) sets a “search range” of the small area searched by the first processing unit (110) on the basis of a result of the foregoing recognition of the lane edges by the second processing unit (120).

摘要： An image processing system and the like capable of improving recognition accuracy of a lane mark are provided. According to the image processing system of the present invention, a first processing unit (110) recognizes a lane mark candidate on the basis of the luminance of each pixel in a road image. Moreover, there are evaluated a first index which represents continuity of an edge of the lane mark candidate, a second index which represents conformance between the width of the lane mark candidate and a lane mark standard width, and a third index which represents uniformity of the luminance of pixels contained in the lane mark candidate. According to the first, second, and third indices, a second processing unit (120) recognizes a lane mark candidate most likely to be a true lane mark as a lane mark.
