Embodiment 1

[0044]Please refer tofigure 1,figure 1A flow schematic diagram of a pipeline leak monitoring method provided by the present invention, the following will be described below to describe steps S110-S150.

[0045]Step S110: A video frame image is obtained; wherein the video frame image is included to be monitored.

[0046]In an embodiment of the present invention, it is necessary to analyze video frame images first. If the tube to be monitored in each video frame image is in a normal state, the table is known to monitor the pipeline in normal state, and in the video frame image When a video frame image is in an abnormal state, the characterization to monitor the pipe is in the presence; that is, the state of the in-video frame image to be monitored in the video frame image can characterize the state in which the pipe is monitored in the video.

[0047]Step S120: Screening the N suspected zone in the video frame image; wherein n ≥ 0, n is an integer, the suspected area, is a region where the to ...

Embodiment 2

[0059]In an implementable manner, step S120 (screening the N suspect area in the video frame image) may be:

[0060]Based on color components and color components, the video frame image is preliminarily screened, and M may be used, wherein M ≥ N, m is an integer; the M may be made based on the full convolutional neural network image division algorithm. Identification, the N-suspected area is screened from it.

[0061]That is, in the embodiment of the present invention, in order to reduce the number of suspected areas and ensure that the hit rate of the suspected area is further reduced, the video frame image can be performed twice after obtaining the video frame image after acquiring the video frame image. To obtain N suspected areas, it can reduce the data processing amount of the subsequent data processing when the video frame image is processed, and the processing speed is increased.

[0062]Further, in the embodiment of the present invention, the color component of the video frame image ...

Embodiment 3

[0090]The third embodiment of the present invention provides a monitoring system for implementing the above-described monitoring method.

[0091]For "UAV real-time recognition mode", the system mainly includes, for example, a video capture device disposed on the drone, and can establish a communication connection with the drone to obtain a video-shot video, a drone handheld terminal device, The drone handheld terminal device further includes a processor and a memory, wherein the processor is configured to perform the "UAV ELC real-time recognition mode" monitoring method described in the memory as described in the memory. Computer program.

Abstract

The invention provides a pipeline leakage monitoring method and system, which relate to the technical field of pipeline monitoring. In this method, by processing the video frame image, the abnormal state of the pipeline to be monitored in the video frame image is judged, and the probability value of the abnormal state of the pipeline to be monitored is calculated. When the probability value of the abnormal state is greater than the preset When the probability threshold is exceeded, an alarm message is output; thereby realizing the intelligent monitoring of the pipeline to be monitored. The scheme provided by the invention not only saves human resources but also improves the monitoring reliability of the pipeline to be monitored.

Description

Technical field[0001]The present invention relates to the field of pipeline monitoring, and more particularly to a pipeline leak monitoring method and system.Background technique[0002]With the development of the economy, the oil gas pipes occupy an increasingly important position in national life, such as natural gas, petroleum, etc., which need to be transported by the oil pipe. When the oil pipe is broken, it will have a huge impact on people's lives. If the oil gas tube is destroyed, it will bring huge safety hazards, and may result in an inefficient economic loss.[0003]In order to reduce the rupture leakage or destruction of the oil gas pipe, it is necessary to monitor the oil pipe to avoid the impact of the damage to the oil pipe. Therefore, the prior art typically passes the video and images of the oil pipe, and the staff is damaged by the video and the image to determine whether the oil pipe is damaged by the video and the image. Among them, if a partial oil pipeline is under...
