Linear structured light pavement surface detection system-based pavement depth image production method
The present invention discloses a linear structured light pavement surface detection system-based pavement depth image production method, a light strip image containing three-dimensional information of a to-be-tested pavement is collected by a vehicle-mounted linear structured light pavement surface detection system, section surface contour lines are extracted from the light strip image, the section surface contour lines are spliced and converted into a pavement surface three-dimensional depth image by selection linear fitting and difference calculation method so as to realize pavement distress detecting free of vehicle wave disturbance. Beneficial effects are that: compared with surface fitting method in the prior art, disturbance caused by a variety of pavement fluctuations and detection system vertical vibration in the actual road detection process can be effectively overcome, so that the obtained pavement depth image is relatively flat, and is free of gray transition, detect effect is better, response is rapid, processing is efficient, and the result is reliable.
