Traffic sign recognition system
A traffic sign recognition system includes a display for displaying caution information of a traffic light, and a processor configured to execute a traffic light detecting module for detecting a traffic light, a bypass lane detecting module for detecting a bypass lane, a line of sight detecting module for detecting a line of sight of a driver, and a vehicle behavior determining module for detecting a traveling direction of a vehicle. The processor controls the display to display caution information when the line of sight is different from a direction of the traffic light, and controlling the display to refrain from displaying the caution information when the detected line of sight matches the direction of the traffic light. The display is refrained from displaying the caution information when the bypass lane is detected and the traveling direction is toward the bypass lane, regardless of the line of sight.
1. A traffic sign recognition system, comprising:
a traffic light detecting module for detecting a traffic light ahead of a vehicle;
a display unit for displaying, for a driver of the vehicle, caution information regarding the traffic light; and
a processor configured to execute:
a bypass lane detecting module for detecting a bypass lane bypassing a road intersection where the detected traffic light is installed, at a position slightly before the vehicle reaches the traffic light;
a line of sight detecting module for detecting a line of sight of the driver;
a vehicle behavior determining module for detecting a traveling direction of the vehicle; wherein
the processor is configured to control the display unit to display the caution information regarding the traffic light when the detected line of sight of the driver is different from a direction of the traffic light, and controlling the display unit to refrain from displaying the caution information when the detected line of sight of the driver matches with the direction of the traffic light,
wherein the processor controls the display unit to refrain from displaying the caution information when the bypass lane is detected at the position slightly before the vehicle reaches the traffic light and the detected traveling direction is toward the bypass lane, regardless of the line of sight of the driver.
2. The system of claim 1 , wherein the processor controls the display unit to display the caution information when the line of sight of the driver is different from the direction of the traffic light and the vehicle has passed an entrance of the bypass lane.
3. The system of claim 1 , wherein the vehicle behavior determining module detects whether the vehicle travels toward the bypass lane based on an operation state of a direction indicator of the vehicle.
4. The system of claim 1 , wherein the bypass lane is for one of left turn and right turn.
