Abstract

The invention discloses a pavement crack detection method, a pavement crack detection device and computer equipment, relates to the technical field of computers, and can solve the problems of low detection efficiency, low accuracy and strong environmental interference which are easily generated when pavement cracks are detected. The method comprises the steps of acquiring and preprocessing a roadcrack image; training a deeplab V3 + network model by using the road crack image; and performing crack detection on the pavement image according to the trained deeplab V3 + network model, and extracting crack information. The method is suitable for detecting the crack area in the pavement.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and computer equipment for pavement crack detection. Background technique [0002] Pavement cracks are one of the most common defects in highway systems, which seriously affect the service life of roads and driving safety. With the continuous advancement of social economy and automation technology, crack detection technology based on computer vision and image processing has gradually been applied in various fields. In the current road crack detection research, the complex and changeable external environment and the diversity of cracks exist make it difficult to accurately extract the attribute characteristics of cracks in complex and similar backgrounds, improve the accuracy of feature clustering, and endow the target model with a powerful Optimizing classification performance and solving the contradiction between algorithm accuracy and speed have alw...
