AI Technical Summary

Technical Problem

Existing GIS equipment inspection suffers from low on-site detection and data collection efficiency and substandard imaging quality, especially on large equipment where full-coverage scanning and 3D reconstruction are difficult to achieve.

Method used

An X-ray image acquisition device was designed, comprising a vehicle body, an X-ray assembly, an imaging assembly, and a control and adjustment assembly. The synchronous movement and adaptive position adjustment of the X-ray assembly and the imaging assembly are achieved through an airbag unit and an adjustment unit, and three-dimensional imaging reconstruction is performed in conjunction with the FDK algorithm.

Benefits of technology

It improves detection efficiency, reduces manual calibration time and on-site adjustment costs, enhances safety, and enables stable three-dimensional imaging of GIS equipment.

Abstract

The invention relates to an X-ray image acquisition device for three-dimensional reconstruction of GIS equipment and an acquisition method thereof, a first airbag unit is arranged in an accommodating cavity, the top end of an adjusting unit is connected with the bottom end of the first airbag unit, and the bottom end of the adjusting unit is in contact with the peripheral wall of the GIS equipment; the X-ray assembly is communicated with the first air bag unit through the first connecting assembly, and the imaging assembly is communicated with the first air bag unit through the second connecting assembly; the acquisition process comprises the steps of mechanical verification, parameter setting, transillumination acquisition and optimization of a three-dimensional imaging reconstruction process; the vehicle body is used for carrying the supporting frame to drive the X-ray assembly and the imaging assembly to move synchronously, and the relative position of the imaging assembly and the X-ray assembly can be adjusted in a self-adaptive mode according to the concave-convex road surface and the height change of GIS equipment in the operation process by controlling the adjusting assembly. On the basis of ensuring the stability of the collection process, the manual calibration time and the manpower, material resources and time cost of field adjustment are saved, the collection efficiency is improved, and meanwhile, the safety is improved.
