Laser Road Surface Profiler functional test on pavement is 2D version.The system adpots the high resolution line scan camera to seamlessly scan the lanes at longitudinal 1mm distance, each 2048mm forms a road image. Infrared laser-assisted illumination is used to achieve normal detection of road in all weather and special environments (such as tunnels, culverts, cloudy days, nights, etc.) to obtain real road images.
1. Full lane coverage, complete data
The system adopts the special structure design of single camera/laser, the designed road surface detection width can reach 3.5m or above, realizing the collection of full-width road surface data.
2.High image quality
The system adopts a filter structure design, which eliminates the influence of natural light and vehicle body shadow on image quality, which ensures the image quality to be clear.
3. Provide exposure and gain adjustment selection
The system supports camera exposure and gain adjustment. During the detecting process, a suitable solution can be quickly selected to improve the efficiency of manual adjustment.
