The invention discloses a method and a
system for monitoring safety of an oil and
gas pipeline based on unmanned aerial vehicle line patrol and a
software storage device. The method comprises the steps of S1, acquiring multi-
source data generated by
safety monitoring of the oil and
gas pipeline with an unmanned aerial vehicle; S2, carrying out
risk identification on a mono-temporal image accordingto a characteristic
library obtained by historical risk characteristic training, carrying out the
risk identification on a multi-temporal image by use of a saturation-based
change detection method toidentify change regions between different time phases, calculating and combining mono-temporal and multi-temporal
risk identification results; S3, reappearing an inspection process of the unmanned aerial vehicle for the oil and
gas pipeline in a three-dimensional platform; S4, carrying out
route planning of the unmanned aerial
vehicle inspection and analysis of a water-flooded space of the pipeline; and S5, outputting a pipeline hidden danger report which includes a risk identification report and a
spatial analysis report, and making a decision according to the pipeline hidden danger report.According to the method and the
system for monitoring the safety of the oil and gas pipeline based on unmanned aerial vehicle line patrol and the
software storage device, the safety management cost ofthe oil and gas pipeline is effectively reduced, the
safety monitoring efficiency is improved and the operation and
maintenance management level of a
pipe network is enhanced.
