Pavement cracks, pits and other diseases that cause road surface technical conditions or road surface performance degradation are generally called as road surface damage. The severity of road damage seriously affects the speed of the vehicle and road.
This laser crack measurement system is 2D version, which adopts line-scan camera and the infrared laser to continuously collect the data of the asphalt pavement and cement concrete pavement. Based on the collected images of the pavement to identify the asphalt pavement disease (11 types of disease such as crack, block crack, etc.)
The laser system adopts 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 conditions and special environments (such as tunnels, culverts, cloudy days, nights, etc.) to obtain real road images.

Features
  • Full lane coverage, complete data collecting
    The laser 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.
