X-ray detection technology-based three-dimensional tomographic reconstruction and slice display method

Abstract

The present invention discloses an X-ray detection technology-based three-dimensional tomographic reconstruction and slice display method. The method comprises the following steps that: (1) X-rays are adopted to scan a detected object, the X-ray projection data of the detected object are obtained; (2) image calibration and image processing are performed on the X-ray projection data; (3) three-dimensional tomographic reconstruction is performed on the X-ray projection data which have been subjected to the image calibration and image processing; and (4) three-dimensional image slice display is performed according to a three-dimensional tomographic reconstruction result. The method of the invention has the advantages of simple steps and convenient operation. With the method adopted, the internal structure and state of equipment can be reproduced realistically in a three-dimension mode with obtained limited data, and inspectors can be facilitated to directly observe and analyze the state of the equipment.

Description

technical field [0001] The invention relates to the field of X-ray detection, in particular to a three-dimensional tomographic reconstruction and slice display method based on X-ray detection technology. Background technique [0002] For electrical equipment such as GIS, circuit breakers, composite insulators, etc., any internal defects and faults may affect the overall performance of the equipment, and may affect the normal operation of adjacent equipment and the normal power consumption of the service area. However, large-scale power equipment such as GIS and tank circuit breakers are huge in size and complex on-site environment. Once an accident occurs, a large amount of manpower, material resources, financial resources and time will be invested in power outage maintenance. Most of the defects inside the power equipment are structural defects. Therefore, in order to reduce or avoid the outage of the power equipment for some reason, it is necessary to detect the internal d...

AI Technical Summary

Problems solved by technology

[0004] 1) Most of the detection methods are aimed at the insulation performance of the equipment, and cannot effectively detect the mechanical structure defects of the invisible parts inside the equipment

[0005] 2) Defects cannot be located, or point-by-point measurement is required in the process of defect positioning, and the workload is huge

[0006] 3) It can only judge whether the defect exists, and cannot intuitively analyze the source and characteristics of the defect

[0007] 4) Some detection methods are easily affected by the detection environment such as equipment structure and mechanical vibration, and there is a risk of misjudgment in the guideline

[0008] 5) Usually, the fault can only be detected when the fault has already occurred or even developed to a more serious level, and it is impossible to effectively detect the defect at the beginning of its formation
