Road marker recognition device and method

A road marker recognition method in a vehicle, the method comprising:

• irradiating, by an infrared transceiver, an infrared beam on a road surface;
• receiving, at the infrared transceiver, the beam reflected from the road to obtain distance information from the road and signal strength information of the reflected beam;
• creating, by a controller, a road map for the road surface using the distance information, the signal strength information, and speed information of the vehicle;
• defining, by the controller, a marker shape of the road surface;
• comparing, by the controller, the marker shape with stored marker information to determine a definition of the marker shape;
• and
• outputting, by the controller, the definition of the marker.

A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:

• program instructions that control an infrared transceiver to irradiate an infrared beam on a road surface;
• program instructions that control the infrared transceiver to receive the beam reflected from the road to obtain distance information from the road and signal strength information of the reflected beam;
• program instructions that create a road map for the road surface using the distance information, the signal strength information, and speed information of the vehicle;
• program instructions that define a marker shape of the road surface;
• program instructions that compare the marker shape with stored marker information to determine a definition of the marker shape;
• and
• program instructions that output the definition of the marker.
