Abstract
Official abstract text for this publication.
A traffic sign recognition system includes a display for displaying caution information regarding a traffic sign ahead of a vehicle, and a processor configured to execute a viewing direction detecting module for detecting a viewing direction of a driver, a traffic sign detecting module for detecting the traffic sign, and a viewing condition detecting module for detecting a viewing condition of the traffic sign. The processor controls the display to display the caution information when the detected viewing direction is different from a direction of the detected traffic sign, controls the display to refrain from displaying the caution information when the detected viewing direction is toward the detected traffic sign, and when the viewing condition detecting module detects a low viewing condition of the traffic sign, controls the display to display the caution information even when the detected viewing direction matches the direction of the detected traffic sign.
First claim
Opening claim text (preview).
What is claimed is: 1 . A traffic sign recognition system, comprising: a display unit for displaying, for a driver of a vehicle, caution information regarding a traffic sign ahead of the vehicle; and a processor configured to execute: a viewing direction detecting module for detecting a viewing direction of the driver; a traffic sign detecting module for detecting the traffic sign; a viewing condition detecting module for detecting a viewing condition indicating visibility of the traffic sign; wherein the processor is configured to control the display unit to display the caution information regarding the detected traffic sign when the detected viewing direction of the driver is different from a direction of the detected traffic sign, and controlling the display unit to refrain from displaying the caution information when the detected viewing direction of the driver matches with the direction of the detected traffic sign, and wherein when the viewing condition detecting module detects a low viewing condition of the traffic sign, the processor controls the display unit to display the caution information even when the detected viewing direction of the driver matches with the direction of the detected traffic sign. 2 . The system of claim 1 , wherein the viewing condition detecting module detects the low viewing condition at night. 3 . The system of claim 1 , wherein the viewing condition detecting module detects the low viewing condition when the vehicle is inside a tunnel. 4 . The system of claim 1 , wherein the viewing condition detecting module detects the low viewing condition in one of rain, snow and thick fog. 5 . The system of claim 1 , wherein the viewing direction detecting module also detects an opening degree of eyes of the driver, and wherein the viewing condition detecting module detects the low viewing condition when the detected opening degree of eyes of the driver is small. 6 . The system of claim 1 , wherein the viewing condition detecting module detects the low viewing condition when the vehicle faces a high intensity light.
