Line laser pavement track detection system with relative datum point

The utility model discloses a line laser pavement track detection system with a relative datum point. The system comprises a positioning system, an image acquisition device and a track image processing module, which are arranged on a vehicle and supplied with power by a vehicle-mounted power source; the positioning system comprises a GPS and a photoelectric encoder; the image acquisition device comprises two high-speed CCD area-array cameras, two line lasers, eight dot lasers and a switch; the track image processing module comprises an industrial computer; the GPS, the photoelectric encoder, the line lasers and the high-speed CCD area-array cameras are all connected to an industrial computer. The line laser pavement track detection system with the relative datum point is characterized in that the datum point line laser pavement track detection technology is developed by combining the laser detection technology and the digital image technology to solve the key problems in track detection at present and improve the track detection accuracy. The line laser pavement track detection system is simple to operate, and convenient to use, and the measurement results are intuitive and reliable; as the measurement results can be as accurate as 1mm, the measurement accuracy is extremely high. The line laser pavement track detection system can be widely applied to road detection.
