Simulation of defects in aluminium castings using CAD models of flaws and real X-ray images
(BRITISH INST NON-DESTRUCTIVE TESTING, 2005)
In order to evaluate the sensitivity of defect inspection systems, it is convenient to examine simulated data. This gives the possibility to tune the parameters of the inspection method and to test the performance of the ...
Sistema imunológico artificial com aprendizagem profunda para detectar defeitos de solda em imagens radiográficas PDVD de tubulações de petróleo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2020-03-25)
In recent years, research focused on (semi)automatic radiographic inspection methods has gained more attention. The present work proposes a method for detecting defects in radiographic images of welded joints of oil pipes. ...
Automated visual testing using trifocal analysis in an uncalibrated sequence of images
(AMER SOC NONDESTRUCTIVE TEST, 2006)
Automated visual testing using multiple views has been recently developed to automatically detect discontinuities in manufactured objects. The principal idea of this strategy is that, unlike the noise that appears randomly ...
