| Abstract:In order to accurately detect the existing bridge diseases, an intelligent detection method of existing bridge diseases based on visual data fusion and machine learning algorithm is studied. Adopt the UAV aerial photography technology of radar and visual data fusion to collect and locate the high-definition image of the bridge in service; Build an in-service bridge disease detection model based on Mask R-CNN convolution neural network, and train the detection model dynamically through the migration learning method to obtain the optimal in-service bridge disease detection model; De-noise and enhance the located high-definition image of the bridge in service, input the detection model for classification and recognition, and output the disease detection results. The experimental results show that this method can quickly and accurately detect a variety of bridge diseases in service, reduce false detection and missed detection, and realize the fine detection of multiple diseases in one map. |
