First Claim
Patent Images
1. A method for detecting a color of a signal light from a moving vehicle comprising:
- capturing an image from a camera mounted on the moving vehicle;
extracting candidate regions in the image that contain a light region;
classifying the candidate regions as a signal light region or a non-signal light region; and
identifying the color of the signal light region.

Abstract
The present invention aims at providing a method for detecting a color of a signal light from a moving vehicle such as railroad train. The method includes capturing an image from a camera mounted on the moving vehicle and extracting candidate regions in the image that contain light region. The method further includes classifying the candidate regions as a signal light region or a non-signal light region and identifying the color of the signal light region.

19. A method for detecting a state of signal lights from a moving vehicle comprising:
-
capturing a video from a camera mounted on the moving vehicle; extracting images from the video; detecting light regions in the image corresponding to the signal light; identifying color of the signal lights; analyzing two or more signal lights; and tracking the detection of the state of the signal light to eliminate a false detection. - View Dependent Claims (20, 21, 22)
