Embodiment Construction

[0096] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0097] The inventor found that the extended length of closed spaces (such as subway stations, underground pipe corridors or cable tunnels) is relatively long. If the point cloud data in the entire closed space is directly collected, not only the workload is large, but the efficiency is low. The subsequent point cloud data In the process of processing, the workload will also be very heavy. Based on this, the closed space equipment inspection method provided by ...

Abstract

The embodiment of the invention discloses a deformation monitoring method and apparatus for equipment in enclosed space. The deformation monitoring method for equipment in enclosed space includes thesteps: performing point cloud data acquisition on the equipment in the enclosed space regionally; for the point cloud data of the equipment in each region, after splicing and denosing, the point clouddata, matching the denoised point cloud data with each point cloud data model in a point cloud data model library so as to determine the first attribute information, of each equipment, represented bythe denoised point cloud data; saving the denoised point cloud data and the first attribute information in a correlated manner; and comparing the denoised point cloud data with the historical point cloud data correlated with the first attribute information to perform deformation analysis on each equipment. The deformation monitoring method and apparatus for equipment in the enclosed space realizes automatic inspection of the equipment in the enclosed space, improves the inspection efficiency of the equipment in the enclosed space, and reduces the probability that the inspection staff is in anunsafe environment, such as anoxia and ponding.

Description

technical field [0001] The present application relates to the technical field of equipment detection, and more specifically, to a method and device for monitoring equipment deformation 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 the present application is to provide a method and device for monitoring deformation of equipment in a closed space, so as to at least partially solve the problems existing in the prior art. [0004] In order to achieve the above object, the application provides the following technical solut...
