Research On High-definition Surround View Intelligent Inspection Of Substation

With the expansion of power station scale,the research of substation intelligent inspection is a hot topic at present.All kinds of intelligent inspection emerge endlessly,each has its own advantages and disadvantages.In view of the shortcomings of the current intelligent inspection: first,the conventional sensor is affected by the electromagnetic environment,resulting in inaccurate data obtained by the sensor;Second,the line of sight is limited,the scope of routine inspection is very limited,and the detection range is not large at the same time;Third,in emergencies,the inspection line cannot be changed in time,so that the inspection efficiency is not high.In this paper,four 210° fisheye cameras are used to obtain the inspection environment information directly.After optimizing the feature point extraction and feature point descriptor in the original Scale-invariant feature transform(SIFT)algorithm,the improved SIFT algorithm after increasing the level threshold is proposed.Restore the real environment of the substation in the current period of the inspection process,reduce the amount of calculation,improve the matching accuracy,and then through the changes of the images before and after,Use the image recognition algorithm combining Princjpal Component Analysis(PCA)and Local Binary Patterns(LBP)to judge whether there are any anomalies in the inspection process,and report the analysis results to the manual data information center.So as to achieve efficient inspection effect,at the same time,the traditional A Star(A *)algorithm optimization and dynamic measure inspired by corner was improved,and the improved A * algorithm to adjust the route inspection,to ensure the quality of inspection and aging,according to the inspection requirements,real-time adjustment circuit,finally realizes the real-time hd look intelligent inspection.Experiments prove that the study has reached the intelligent inspection standard,the results of the study is a good way to save human resources,more intuitive,real-time detection of abnormal phenomenon in a substation,as soon as possible to solve the problem of abnormal,have very good social value and economic value,in substation intelligent inspection industry with good promotion prospect,has certain advancement.
