ROAD SIGN RECOGNITION DEVICE

摘要

In a road sign recognition system, a high luminance region indicating a region with a luminance higher than a predetermined reference luminance in the captured image is extracted (S120, S220), and a vehicle light source that represents a light source derived from the vehicle in the captured image is extracted (S130, S230). Then, a region that matches the vehicle light source in the high luminance region is excluded (S140, S240), and another region excluding the region that matches the vehicle light source in the high luminance region is set as a target region for recognizing the road sign (S150, S250), and the road sign is recognized in the target region. As a result, it is possible to narrow the region of performing the process of recognizing the road sign, thus it is possible to reduce the process load during recognizing the road sign.

主权项

1. A road sign recognition device, which is employed on a vehicle, that recognizes a road sign in a captured image, comprising:
a first means for extracting a high luminance region indicating a region with a luminance higher than a predetermined reference luminance in the captured image; a second means for extracting a vehicle light source that represents a light source derived from the vehicle in the captured image; a third means for excluding a region that matches the vehicle light source in the high luminance region; and a fourth means for setting another region excluding the region that matches the vehicle light source in the high luminance region as a target region for recognizing the road sign, and recognizing the road sign in the target region.
