Abstract

The invention discloses a method and device for detecting a damaged area in an expressway and computer equipment, relates to the technical field of computers, and can solve the problems that when thedamaged area in the expressway is detected, the detection efficiency is low, the accuracy is low, and the danger coefficient is high. The method comprises the following steps: carrying out edge detection on an obtained target detection picture by utilizing an edge detection algorithm; segmenting a lane area picture from the target detection picture according to an edge detection result; and performing damage detection on the lane area according to the lane area picture, and extracting lane damage information. The application is suitable for detecting the damaged area in the expressway.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and computer equipment for detecting damaged areas in expressways. Background technique [0002] The expressway has the characteristics of large traffic volume, fast speed, and heavy load. Therefore, during the long-term operation, it will be affected by natural factors and vehicle loads, which will cause certain damage to the roadbed and pavement, thus affecting the road. Usability, causing safety hazards to passing cars, so improving road surface detection technology, enhancing the accuracy and timeliness of road surface damage detection, has important research significance for the modernization level of highways, especially expressways. [0003] As far as the development of pavement detection technology at home and abroad is concerned, the automation level and detection accuracy of pavement damage detection need to be further improved. Low, low ac...
