Bridgehead bumping judgment method based on point cloud technology

Abstract

The invention provides a bridgehead bumping judgment method based on a point cloud technology. The method comprises: arrangement and collection of a point cloud scanner, generation of a three-dimensional landform, preprocessing of point cloud data, gridding of the point cloud data, elevation plane fitting, generation of an elevation difference matrix, and judgment and treatment of the severity of bridgehead bumping. The method can be used for judging the full-width road bridgehead bumping condition, is high in detection speed, high in precision and large in detection range, breaks through the obstacle that only a single side line can be detected in the past, ensures the accuracy of quick judgment of bridgehead bumping, and can find problems in time and dispose the problems in time. The method has important practical significance for improving the road maintenance level, guaranteeing the road driving quality and guaranteeing the road safety, and can be widely applied to judgment of high-grade road bridgehead bumping.

Description

Technical field [0001] The present invention belongs to the field of road maintenance technology, and more particularly to a bridge head jumper determination method based on point cloud technology. Background technique [0002] Bridgehead jumping is a typical pavement disease in my country's high-grade road. With the improvement of road level, the bridge tunnel ratio is getting bigger and larger, and there are more frequent frequencies that the bridgehead hopper disease occurs. The disposal work of hip-going diseases is increasingly one of the focus of the highway maintenance department. The conventional inspection method is only a driving survey. It can only be judged if the hopping is more serious. The road maintenance worker has systematically studied the fast-scale judgment of the highway bridge head jumped. The first time I propose a method of determining the bridgehead jumper using the road surface flatness, and it also proposes corresponding disposal measures, but the disp...

Problems solved by technology

[0003] Aiming at the outstanding problems of the existing method of judging vehicle jumping at the bridge head by using the road surface smoothness and corresponding disposal measures, such as waste of time, low safety, and small amount of data collection, the present invention proposes a vehicle jumping judgment at the bridge head based on point cloud technology The method has fast detection speed, high precision, and large detection range. It breaks through the obstacle of only detecting a single lane in the past, and has important practical significance for improving the level of road maintenance, ensuring road driving quality, and ensuring road safety.
