Desarrollo e Implementación de un Sistema de Visión Artificial para Ensayos No Destructivos por Radiografía en Soldadura

Abstract

The artificial vision is an applicative field in engineering, applied o repetitive and sometimes dangerous processes in the industry. The present investigative project searches to develop an important tool to use in the nondestructive essays, in the identification of discontinuities with a software that allow the processing of the images in Industrial Radiography with the recompilation of acceptation criteria of discontinuities according to API 1104. In order to process the image in radiographic films with the help of the language program of MATLAB, that allows a great versatility of image processing and data analysis, giving and efficient response, fast and easy to understand, offering a tool with a graphic interface very friendly with the user. The software made identifies the form, area, perimeter of the shown figures in the radiographic film of welding that, through image filter and metric relationships of area and perimeter, distinguish the contour of the discontinuities to analyze them and evaluate them according to the norm. The program will be implemented in the Nondestructive Essays laboratory of the Mechanical Engineering School, to the use of the students that are taking the subject in order to interpret better the knowledge of the proceedings of industrial radiography. The project is focused to optimize and to ease the process of the nondestructive essays, decreasing the work fatigue to the user in the interpretation of the defects of the welding in the radiographic industry.
