Problems solved by technology

The semi-manual method uses a camera to take pictures of the road surface, and then manually screens them, which requires a lot of human resources; the detection vehicle has relatively high requirements for hardware equipment, high cost, and requires manual processing of offline data, which cannot realize fully automated detection of road damage , not only affects the traffic environment, but also the final recognition effect is general
The more well-known ones are the Kumatsu system in Japan and the MRMS inspection vehicle in the United Kingdom. Using sensors, cameras, laser scanners and other equipment, sensors and laser scanners are used to obtain analog signals on the road surface, and the analog signals are converted into digital signals for processing. High cost and low recognition rate, and can only recognize pictures, cannot determine the location, and has not been widely used

Abstract

The embodiment of the invention discloses a road detection method, a device, equipment and a storage medium. The method comprises the steps of in the running process of a vehicle, collecting images ofroads passed by the vehicle and position information of the vehicle, and determining the collection time of the road images and the collection time of the position information of the vehicle; and ifit is detected that the road surface damage exists in any road image, matching the acquisition time of the road image with the acquisition time of the vehicle position information, and determining thevehicle position information associated with the road image according to a matching result. According to the method, the road surface picture and the vehicle passing position are obtained, after thedamaged road surface picture is detected, the position of the damaged road surface is obtained by obtaining the position information with the same time as the shot picture, the cost is effectively reduced, manpower and material resources are saved, and the road detection efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technology, and in particular to a road detection method, device, equipment and storage medium. Background technique [0002] With the continuous development of the national economy, the total mileage of roads in my country's transportation network has increased rapidly, which has greatly increased the workload of road maintenance in the later period. The prevention and control of road surface damage and disease has been paid more and more attention by the road maintenance department. Timely and accurate identification of road surface damage and disease It is the first step in pavement maintenance. [0003] Currently applied road damage detection methods are divided into two categories: semi-manual and detection vehicle-based methods. The semi-manual method uses a camera to take pictures of the road surface, and then manually screens them, which requires a lot of human resources; the detec...
