AI Technical Summary

Problems solved by technology

However, when two vehicles are driving close to each other, the road image may not be captured, and therefore, the information marked on the road may not be correctly recognized
Cameras may not capture images in wet weather conditions or in low light
In addition, the algorithms and processing logic for sign recognition can be complex, increasing the time required to identify road obstacles

Abstract

Disclosed are a road surface marker recognition device and a method. The device includes an infrared transceiver that is configured to irradiate an infrared beam on a road surface and receive the reflected beam to detect a distance from a road surface and the strength of the reflected beam. The device further includes a controller that is configured to create a road map of the road using distance information, signal strength information, and speed information of a vehicle so as to define a marker shape of the road. Furthermore, the controller is configured to compare the defined marker shape with stored marker information to determine a definition of the marker shape and output the marker shape definition.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2012-0139616 filed with the Korean Intellectual Property Office on December 4, 2012, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a road sign recognition device, more particularly, to a road sign recognition device capable of acquiring road information by using infrared rays and using the road information to identify signs. Background technique [0004] Recently, research has been conducted on vehicle safety measures such as seat belts and air bags capable of minimizing driver injuries in vehicle accidents. Specifically, the research concerns methods for predicting potential accidents and warning drivers to prevent accidents and thereby improve driver safety. [0005] Traditional safety methods include Advanced Safety Vehicle (ASV) technology,...
