Closed space device inspection method and apparatus

Abstract

The embodiments of the present invention disclose a closed space device inspection method and device. According to the closed space device inspection method and apparatus of the invention, point clouddata collection is performed on devices in different regions in a closed space; after splicing and de-noising processing is performed on the point cloud data of the devices in each region, and the de-noised point cloud data are matched with each point cloud data model in a point cloud data model library, so that the first attribute information of each device, which is represented by the de-noisedpoint cloud data, can be determined; the de-noised point cloud data and the first attribute information are saved in an associated manner; the de-noised point cloud data are compared with historicalpoint cloud data associated with the first attribute information, so that abnormality analysis can be performed on the devices which are represented by the de-noised point cloud data; and therefore, the automatic inspection of the devices in the enclosed space can be realized, the inspection efficiency of the devices in the enclosed space can be improved, and the probability that inspection personnel are exposed to an unsafe environment such as lack of oxygen and water can be lowered.

Description

technical field [0001] The present application relates to the technical field of equipment detection, and more specifically, to a method and device for inspection of equipment in a closed space. Background technique [0002] At present, equipment in closed spaces (such as subways, underground pipe corridors, etc.) mostly adopts the inspection mode of manual inspection or manual fault location. However, the operating environment of equipment in enclosed spaces is narrow and the ventilation and lighting are poor. Manual inspection is not only time-consuming There are also unsafe factors such as lack of oxygen and stagnant water. Contents of the invention [0003] The purpose of this application is to provide a closed space equipment inspection method and device to at least partly solve the problems existing in the prior art. [0004] In order to achieve the above object, the application provides the following technical solutions: [0005] A closed space equipment inspectio...
