Abstract

The invention discloses a method for removing redundancy of drainage pipeline defects, and relates to the technical field of pipeline detection; the method includes the following steps: S10, reading a picture frame; S20, simultaneously using a VGG-Sewer model and a residual network ResNet-18 to perform Defect recognition; adding a new fully connected layer between the last two fully connected layers in the VGG-16 model to form a VGG-Sewer model for dimensionality reduction of image features; S30, judging whether it is a defective image, if so , then enter the next step, if not, return to step S10; S40, read the configuration file and select the model; S50, obtain the L2 distance of the defect image features of two adjacent frames; S60, judge whether the distance between the images meets the threshold; The beneficial effect of the invention is that the de-redundancy rate is improved and the calculation amount is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, and more specifically, the invention relates to a method for eliminating redundancy of drainage pipeline defects. Background technique [0002] Drainage pipes are one of the important infrastructures of the city and an important part of the urban underground space. The safe operation of drainage pipelines is directly related to the public safety and environmental protection of the city. The long-term operation of the drainage pipeline will cause structural and functional defects of the pipeline. As a result, major safety hazards such as road subsidence, groundwater pollution, and urban waterlogging have been caused. CCTV video damage detection method is the main means of drainage pipeline defect detection. Fatigue and other factors cause false detection, missed detection, etc., and the efficiency of this method is low. [0003] According to the characteristics of drainage pipeline d...
