Lane line transverse distance measuring system and method thereof

Abstract

The invention discloses a system and a method for measuring the transverse distance of a lane line. The system comprises a PC terminal, two measuring tools and two cameras, the two measuring tools are horizontally arranged on the left side and the right side of a vehicle respectively, the two cameras are arranged on the left side and the right side of the vehicle respectively, the cameras can shoot scales on the measuring tools on the same side, the two cameras are connected with the PC terminal, and the cameras transmit shot image data to the PC terminal so as to record the transverse distance of the vehicle relative to lane lines on the two sides. According to the lane line transverse distance measuring system and the method thereof, the transverse distance of the vehicle relative to the lane line can be accurately measured in real time, and the system and the method are visual, rapid, low in cost and high in precision.
