Road surface division mark recognition apparatus, and lane departure prevention apparatus
Abstract:
A road surface division mark recognition apparatus includes: a vehicle-mounted camera that takes an image of a road surface ahead of a vehicle; an image processing portion which has a plurality of image processing modes that correspond respectively to a plurality of kinds of road surface division marks, and which recognizes a road surface division mark in a selected image processing mode; a temperature measurement portion that measures the temperature of the vehicle-mounted camera; and a restriction portion that restricts the action of the vehicle-mounted camera if the temperature measured by the temperature measurement portion is higher than or equal to a threshold value. The threshold value differs between the image processing modes.
