X-ray real-time imaging and CT tomography integrated intelligent non-destructive testing system

Abstract

The invention belongs to the field of non-destructive testing, and in particular relates to an integrated intelligent non-destructive testing system of X-ray real-time imaging and CT tomographic scanning. The system can realize the detection and imaging of DR and CT at the same time, realize the integration of DR / CT data acquisition, processing, automatic defect detection and display, and provide the internal structure information of the measured object from different perspectives for the inspectors, so as to comprehensively judge the internal structure of the object The nature and state of the defect; and the defect identification technology integrated in the system can automatically identify the size, location and type of the defect, thereby effectively reducing the pressure of the inspector to identify the defect and improving the detection efficiency.

Description

technical field [0001] The invention belongs to the field of non-destructive testing, and in particular relates to an integrated intelligent non-destructive testing system of X-ray real-time imaging and CT tomographic scanning. Background technique [0002] In recent years, with the advancement of computer science and the development of detector technology, X-ray imaging and industrial CT technology, as a practical nondestructive testing method, have been widely used in nondestructive testing and quality assessment. X-ray imaging, also known as DR imaging, irradiates the object under test with X-rays, so as to obtain a superimposed image of the internal information of the object in the X-ray direction, which can more intuitively present the long strip-shaped defects inside the object along the axial direction. On the premise of no damage to the test object, industrial CT imaging integrates DR image data in different directions of the object, uses high-performance computers ...

AI Technical Summary

Problems solved by technology

In the process of quality inspection, DR and CT inspection processes are separated. On the one hand, the inspection efficiency is low;

[0004] Whether it is DR or CT, the identification of defects in the image and the final judgment of whether the product is good or bad still require manual participation. Long-term manual identification of defects in the image will also make people tired, resulting in reduced recognition accuracy and detection efficiency. thereby affecting product testing

At present, random inspection is usually used to judge the quality of a batch of products, but this method cannot guarantee the quality of products to a certain extent

At the same time, with the expansion of production, the contradiction that the detection efficiency cannot meet the production efficiency will become more and more prominent
