Radiographic testing weld image management system and auxiliary film viewing method

Abstract

The invention relates to a radiographic testing weld image management system and an auxiliary film viewing method which belong to the methods of assessing welding quality by utilizing computers. The image management system is deployed on a server system, the system is visited through a client computer; the image management system comprises a function module, the function module adopts the design of a B / S four-layer architecture comprising a presentation layer, a business logic layer, a persistence layer and a database layer and further supports the functions of remote browsing and film viewing; and the function module comprises an image acquisition module, an image parameter acquisition module, an image processing module, a film viewing management module, a query statistics module and a system management module. The management system and the film viewing method are applied in a network environment, can register a digitalized radiographic testing film and the related parameter specification in an image database and can query and carry out the classified statistics; the coarse support vector machine classified modeling method is adopted for classified recognition and extraction of welding defects, thereby making the corresponding assessment of the welding quality according to standards.

Description

technical field [0001] The invention relates to a method for managing radiation detection welding images by computer and evaluating welding quality according to defect information in the welding seam images, in particular to a radiation detection welding seam image management system and an auxiliary film evaluation method. Background technique [0002] There are many inspection files produced after traditional film-based radiographic inspection, and the current welding radiation inspection files are still stored in traditional paper documents or film, which are easily affected by external factors such as time, temperature, humidity, etc. The shedding and oxidation of the drug film will cause the loss of documents or film information, and bring irreparable economic losses to the enterprise. Moreover, these documents or negative files take up a lot of space, the management is chaotic, and retrieval is difficult, which brings great inconvenience to the tracking and statistical ...

Problems solved by technology

[0002] There are many inspection files produced after traditional film-based radiographic inspection, and the current welding radiation inspection files are still stored in traditional paper documents or film, which are easily affected by external factors such as time, temperature, humidity, etc. The shedding and oxidation of the drug film, etc., resulting in the loss of document or film information, bringing irreparable economic losses to the enterprise

Moreover, these documents or negative files take up a lot of space, the management is chaotic, and retrieval is difficult, which brings great inconvenience to the tracking and statistical analysis of the quality of welded components, and makes the quality management and evaluation of corresponding welded components very difficult.

At the same time, the traditional film review method is manually completed by the film review staff in the film viewing room with the help of light viewing films, magnifying glasses, measuring rulers, and recording forms, which is easily affected by factors such as equipment, environment, negative film quality, and human physiological conditions. Influence, resulting in misjudgment and missed judgment of welding defects, causing quality hidden dangers to welded structures

Therefore, this traditional film management and film evaluation method has been difficult to meet the requirements of the market and enterprise development, and it is the general trend to apply modern information technology and methods to carry out fundamental reforms on enterprises.

At present, the research on the image management system of digital radiography is still designed based on the traditional C / S (client / server) architecture, which is not conducive to the upgrade of the image management system and the cost is high
