Abstract

The present invention provides a road inspection system and method based on vehicle-mounted laser radar. The system includes: vehicle-mounted inertial navigation device, single-line laser radar, high-precision GPS positioning equipment and vehicle-mounted edge computing smart box; based on the system, a A road inspection method based on a vehicle-mounted laser radar comprises the following steps: equipment installation, data collection, data processing, and data uploading. The road detection system and method proposed by the present invention have low requirements on the measurement environment, and the detection range is wide, and a single measurement can meet the road detection of multiple lanes and full road width, and the detection result has high precision; and because the measurement method is vehicle-mounted measurement , fast measurement speed, high efficiency, suitable for large-scale road inspection, can greatly shorten the detection cycle, effectively shorten the detection frequency under the same detection coverage, and save labor costs.

Description

technical field [0001] The invention relates to the field of road intelligent rapid inspection, in particular to a road inspection system and method based on a vehicle-mounted laser radar. Background technique [0002] With its fast, convenient, and door-to-door direct access, road transportation ranks first among the five transportation modes including road, railway, aviation, pipeline, and water transportation, and occupies an extremely important position in the country's economic development. As of the end of 2019, the total mileage of roads open to traffic in my country has exceeded 5.01 million kilometers. While new roads are being built, maintenance and repairs must be carried out on the original roads to ensure driving safety and reduce operating costs. But on the one hand, there are many disadvantages in traditional road detection methods, such as manual operation methods such as hand-push profiler method, which are time-consuming, labor-intensive and troublesome to ...
