Abstract

The invention discloses a pothole detection method based on improved YOLOv3, comprising: S1, collecting pothole images through a visual acquisition system, obtaining a pothole data set after preprocessing, and the pothole data set includes the preprocessed pothole images ; S2, constructing an improved YOLOv3 pothole detection network model; S3, inputting the training data set of the pothole data set into the improved YOLOv3 pothole detection network model training, when the improved loss function approaches zero , obtain the parameter optimal solution of the improved YOLOv3 pothole detection network model; S4, input the pothole data set into the improved YOLOv3 pothole detection network model of the parameter optimal solution, and obtain the pothole Test results. The invention solves the problem that the detection of potholes must not only ensure real-time performance, but also further improve the accuracy rate.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an improved YOLOv3-based pothole detection method. Background technique [0002] Potholes are bowl-shaped road obstacles with irregular closed curve openings, which can easily change the driving state of unmanned vehicles and eventually lead to traffic accidents. The traditional pothole detection algorithm mainly uses geometric features such as the texture of the pothole as the basis for pothole detection, which has the problems of low pothole detection accuracy and insufficient real-time performance. At present, deep learning has become the mainstream method of object detection, including the detection of potholes using two-stage, multi-stage and single-stage algorithms. The two-stage detection algorithm Faster RCNN and the multi-stage detection algorithm Cascade RCNN have high detection accuracy, but cannot meet the real-time requirements. On the contrary, the single...
