Method and apparatus for tunnel decision
First Claim
Patent Images
1. A tunnel decision apparatus, comprising:
- a camera, the camera outputting an image of a view in front of a vehicle;
circuitry configured to detect a vanishing point from the image of the view in front of a vehicle to output at least one of a road area and a non-road area;
circuitry configured to detect at least one of a lamp pattern from the non-road area and a lane pattern from the road area; and
circuitry configured to determine whether the vehicle enters a tunnel in consideration of at least one of the lamp pattern and the lane pattern, and whether the vehicle escapes the tunnel in consideration of at least one of a duration time of detection and a detection frequency of the lamp pattern.

Abstract
The present invention provides a tunnel decision apparatus, including: a camera which outputs an image of a view in front of a vehicle; a road area classifying unit which detects a vanishing point from the image of the view in front of a vehicle to output at least one of a road area and a non-road area; a pattern detecting unit which detects at least one of a lamp pattern from the non-road area and a lane pattern from the road area; and a tunnel decision unit which determines whether the vehicle enters a tunnel in consideration of at least one of the lamp pattern and the lane pattern.
