Abstract: An apparatus for identifying a line marking on a road surface. In the apparatus, an extractor extracts a paint candidate that is a candidate for road surface paint used to identify a line marking in an image captured by a camera mounted on a vehicle to capture an image of an area including a road surface ahead of the vehicle. A determiner determines whether or not the paint candidate has at least one predefined flare feature. A line marking identifier identifies a line marking using the paint candidate which meets an identification condition used to identify a line marking. The line marking identifier sets the identification condition to be more stringent for a flare paint candidate that is the paint candidate determined by the determiner to have the at least one predefined flare feature than for the paint candidate determined by the determiner to have no predefined flare feature.

Abstract: In a road recognition apparatus mounted in a vehicle, a shape change point detector is configured to detect a shape change point along each of lane lines of an own lane. A turn-off lane determiner is configured to, if the shape change point is detected, determine whether or not a shape changing lane line that is one of the lane lines including the shape change point constitutes a border of a turn-off lane branching off from the own lane. A road recognizer is configured to, when the shape change point has been detected, use only feature points of the left and right lane lines of the own lane located within a distance from the own vehicle to the shape change point to recognize the shape of the own lane, before a result of determination by the turn-off lane determiner is produced.

Abstract: A method includes: recognizing a signal candidate position around a vehicle by using a sensor mounted on the vehicle, the signal candidate position being a position a traffic light is possibly present, the vehicle including a light configured in such a manner that a light distribution state of the light changes; and performing a first light control process of controlling the light in response to recognition of the signal candidate position, the first light control process including at least one of: increasing an intensity of light emitted to the signal candidate position to a value higher than before the recognition of the signal candidate position; or making the intensity of the light emitted to the signal candidate position higher than an intensity of light emitted to an area other than the signal candidate position.

Abstract: An estimating device includes: a movement amount computing section that, on the basis of a position of a predetermined region within an image picked-up at a first time, and a position of a region that corresponds to the predetermined region and is within an image picked-up in a same direction at a second time that is after the first time, computing a movement amount of the predetermined region in a vertical direction; a movement amount integrating section that computes an integrated value of the movement amounts, each time the movement amount is computed; a correcting section that corrects the integrated value of a current point in time on the basis of time series data of the integrated values of the movement amounts within a past predetermined time period; and an estimating section that estimates a pitch angle of the vehicle on the basis of a corrected integrated value.

Abstract: A complex marking determining device includes a brightness state calculating portion configured to calculate a lane marking representative value indicative of a brightness state of a plurality of pixels that make up a lane marking display region, and calculate a road surface representative value indicative of a brightness state of a plurality of pixels that make up the road surface display region; and a complex marking determining portion configured to determine that the lane marking is a complex marking at least when a degree of deviation between the lane marking representative value and the road surface representative value is equal to or greater than a first threshold value.
