Abstract

The invention provides a road inspection system and method based on a vehicle-mounted laser radar. The system comprises a vehicle-mounted inertial navigation device, a single-line laser radar, a high-precision GPS positioning device and a vehicle-mounted edge computing intelligent box. The road inspection method based on the vehicle-mounted laser radar is provided based on the system and comprises the following steps of device installation, data acquisition, data processing and data uploading. The road detection system and the road detection method provided by the invention have the advantages of low requirement on a measurement environment, wide detection range, realization of multi-lane and full-road-width road detection through single measurement, and high precision of a detection result. Moreover, the measurement mode is vehicle-mounted measurement, the measurement speed is high, the efficiency is high, the method is suitable for large-range road detection, the detection period can be greatly shortened, the detection frequency is effectively reduced under the same detection coverage range, and more labor cost is saved.

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 ...
