Lane boundary lane recognition device and computer-readable storage medium storing program for recognizing lane boundary lines on roadway

摘要

In a lane boundary line recognition device, a calculation section calculates a degree of uncertainty which affects a correct recognition of white lines on a roadway of a vehicle. A learning section updates a learning value of the degree of uncertainty. A recognition suppression section suppresses execution of a recognition process of recognizing white lines on the roadway when the updated learning value is more than a threshold value. An environment change judgment section judges whether or not a road environment has changed. A learning resetting section resets the learning value of the degree of uncertainty to a previous learning value when the detection result of the environment change judgment section indicates an occurrence of change of the road environment.

主权项

1. A lane boundary line recognition device capable of recognizing lane boundary lines on the basis of road images captured by an in-vehicle camera, the lane boundary line recognition device comprising:
a calculation section capable of calculating a degree of uncertainty which affects a correct recognition of lane boundary lines on a roadway on which an own vehicle drives; a learning section capable of updating a learning value of the degree of uncertainty which affects the correct recognition of lane boundary lines; a recognition suppression section capable of suppressing an execution of the recognition of lane boundary lines when the learning value of the degree of uncertainty updated by the learning section is more than a threshold value; an environment change judgment section for judging whether or not a road environment has changed; and a learning resetting section for resetting the learning value of the degree of uncertainty to a previous learning value when the detection result of the environment change judgment section indicates an occurrence of change of the road environment.
