The 13th Five-Year Plan for Highway Development proposes: "Promote scientific decision-making on maintenance. The scientific decision-making system for national and provincial highway maintenance has been basically established, the coverage rate of technical condition detection and automatic pavement collection has reached 100%, and the popularization rate of scientific decision-making technology has reached 80%. ”
The state vigorously promotes the construction of a national road pavement maintenance collection and monitoring system to improve traffic and transportation safety. The road comprehensive inspection vehicle is a highly integrated equipment that realizes the automatic collection of pavement conditions, and applies non-inductive detection technologies such as ground penetrating radar and 3D vision to fully obtain various defects and disease data of the road, and regularly upload it to the road maintenance system, and then the road maintenance system carries out maintenance treatment.
The system can also be extended from highway pavement to airport runway surface detection, monitoring the flatness of the take-off road, foreign object detection, etc.; There are also more and more applications in bridges, stadiums and other scenarios.
Application difficulties
Basic performance requirements for hardware: large field of view, high speed, high-precision detection;
The pavement is complex, and there are interference factors such as debris, water stains, oil stains, shadows and natural light, and automatic damage recognition has always been an important bottleneck affecting efficiency.
The 2D line scanning grayscale image only reflects the gray characteristics of different objects on the road surface, such as the gray difference between the normal road surface and the edge of the crack or pothole, and cannot reflect the damage without obvious edge features such as ruts, bulges, and subsidence, resulting in the inability to accurately detect damage such as rutting, subsidence, looseness, and bulging.
Application schemes
Vision integrators use Ranger3 to flexibly match lenses and lasers to integrate customized all-in-one cameras, and one road inspection vehicle is equipped with at least two sets of Ranger3 cameras;
