Embodiment 1

[0075] Embodiment one: if Figure 1-2 As shown, this embodiment involves a pipeline inspection system based on deep learning and UAV. The UAV inspection system is divided into two parts: the on-board inspection system and the ground station inspection system, wherein the on-board inspection system It is composed of four subsystems: UAV, detection, wireless communication and data management (such as figure 2 shown).

[0076] The ground station system is the command center of the entire line inspection system. Its main tasks are flight control, route planning, receiving image information of line inspection and displaying it in real time, wireless communication, and data transmission and processing.

[0077] The UAV subsystem is mainly the selection and control of the UAV body. UAVs are mainly divided into three categories: fixed-wing UAVs, unmanned helicopters, and multi-rotor UAVs. The characteristics and applicable places of each type of UAVs are different. The comparative ...

Embodiment 2

[0094] Embodiment two: if Figure 3-10 As shown, a pipeline detection method based on deep learning and unmanned aerial vehicles involved in this embodiment, the oil pipeline detection subsystem based on deep learning, mainly processes the pictures of oil pipelines collected by unmanned aerial vehicles, through The trained neural network model marks the possible leak areas in it, so as to realize the automation of detection. The scheme is as follows image 3 shown.

[0095] The specific steps are implemented as follows:

[0096] (1) Image preprocessing

[0097]Bilateral filtering is used to denoise the image. Since the cracks in the oil pipeline are relatively sharp, the requirements for edge preservation are relatively high. The Gaussian filter function based on the spatial distribution of the bilateral filter can achieve very good edge preservation. It is near the edge and far away. The pixels will not have much effect on the values ​​of the pixels on the edge. Based on ...

Abstract

The invention provides a pipeline detection system and method based on deep learning and an unmanned aerial vehicle, and belongs to the field of industrial robots. A ground station part comprises a data management module and a first wireless communication module. An airborne part comprises a second wireless communication module, a visible light camera, an infrared camera, a detection system airborne control part and a memory. The method comprises steps of adopting a bilateral filter to denoise an image; carrying out edge detection on the image by adopting a Canny operator and then mapping theimage back to the original image to carry out sharpening operation; simplifying the convolution and pooling operation into a feature map which can be recognized by a feature extraction network; constructing an RPN network to perform prediction regression on a target box in the feature map; carrying out standard post-processing through SoftNMS, and reserving a prediction box with the highest prediction score as detection output; and generating a target mask image, namely a final pipeline detection image. The oil pipeline electric leakage identification accuracy and efficiency are high; automatic detection of the oil pipeline is realized, the labor cost is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a pipeline detection system and method based on deep learning and unmanned aerial vehicles, belonging to the field of industrial robots. Background technique [0002] In the thesis "Design and Implementation of Intelligent Inspection System for Oil and Gas Pipelines", based on the daily inspection and maintenance requirements of oil pipelines, the intelligent inspection management of oil and gas pipelines is realized by using GPS positioning technology, GIS (Geographic Information System) and data transmission technology . Utilize the existing GIS data of oil fields and oil pipelines to visually display the inspection distance of oil pipeline inspectors and the fault points to be tested in the form of graphics, and use GPS to monitor the inspection personnel of oil pipelines. The route and location are positioned, so that the working status of the oil pipeline inspection personnel can be monitored in a timely manner; for oil p...
