Road patrol result duplicate removal method based on similarity measurement

The invention provides a road patrol result deduplication method based on similarity measurement, which belongs to the technical field of road engineering, and comprises the following steps: 1, collecting a road patrol result; 2, preprocessing the converted data of the road patrol result; 3, dividing the preprocessed data set into a training set and a test set; 4, extracting image features by adopting a twin network model to obtain feature vectors of the input image; 5, calculating the distance between the feature vectors of the input image group to obtain the similarity; 6, dividing a threshold value according to the distribution condition of the similarity in the test set, and determining whether the input picture group is the same disease or not according to the threshold value; 7, gathering and clustering inspection results for multiple times; according to the method, the uniqueness and the accuracy of the road disease data are improved, the road disease patrol result can be provided for a road management
