  • Patent number: 11295429
    Abstract: An imaging abnormality diagnosis device includes one or more processors configured to: detect a lane line in an image of a road surface captured by a camera mounted on a vehicle; estimate a shape of a road on which the vehicle is traveling, based on an output of a detector mounted on the vehicle, the detector being other than the camera; and detect as a distorted area an area in the image where the shape of the road and a shape of the lane line do not coincide with each other.

  • Patent number: 11157753
    Abstract: A road line detection device includes a processor configured to: calculate, for each pixel of an image acquired by a camera mounted on a vehicle, a confidence score that a road line is represented in the pixel, and a confidence score that another object is represented in the pixel; set a correction region in a range assumed to include a road line in the image during changing lanes; correct, for each pixel included in the correction region, the confidence score for a road line or the confidence score for another object in such a way that the confidence score for a road line is high relative to the confidence score for another object; and detect a road line from the image based on each pixel in which the confidence score for a road line is higher than the confidence score for another object.
