Cruising zone division line recognition apparatus

摘要

A cruising zone division line recognition apparatus has an image acquisition device that acquires an image including a road surface ahead of a vehicle, and an image recognition device. The image recognition device adds blurring to an area including the road surface in the acquired image and recognizes a cruising zone division line from the image to which blurring has been added. When blurring is added, a cruising zone division line that is an intermittent double line included in a captured image can be made unclear. Therefore, the recognized cruising zone division line can be prevented from becoming a discontinuous, disjointed line.

主权项

1. A cruising zone division line recognition apparatus comprising:
an image acquisition device that acquires an image including a road surface ahead of a vehicle; and an image processing device that adds blurring to an area including the road surface in the image acquired by the image acquisition device, and recognizes a cruising zone division line from the image to which blurring has been added, wherein: the image processing device adds, to the area including the road surface, a larger degree of blurring in the area including the road surface as the area becomes closer to the vehicle and a smaller degree of blurring as the area becomes farther from the vehicle; and the image processing device sets an amount of blurring to be added for each of a predetermined road surface area near the vehicle and a road surface area that is farther than the predetermined road surface area so that a total sum of blurring is fixed at all times.
