Weld Joints Inspection Using Multisource Data and Image Fusion
The problem of inspecting weld joints is very complex, especially in critical parts of machines and vehicles. The welded joint is typically inspected visually, chemically or using radiography imaging. The flaw detection is a task for specialized personnel who analyze all the data on each stage of the inspection process separately. The inspection is prone to human error, and is labor intensive. In the stages of weld joint visual control geometrical measurements are performed, joint alignment, straightness, deformation, as well as the weld\u27s uniformity. Coloration my show the heat impact zone, and melted parts of the base material. Also during this stage the unwanted cracks, pores and other surface defects can be spotted. On the other side during the X-ray inspection other flaws can be discovered. Pores, cracks, lack of penetration and slag inclusions can be observed. The author’s goal was to develop a multisource data system of easier flaw detection, and possibly inspection process automation. The methods consisted of three image sources: X-ray, laser profilometer, and imaging camera. The proposed approach consists combining spatial information in the acquired data from all sources. A novel approach of data mixing is proposed to benefit from all the information. The signal form the profilometer enables geometrical information extraction. Deformation and alignment error assessment. The radiogram provides information about the hidden flaws. The color image gives information about texture and color of the surface as well as helps in combining multiple sources
Administracja, zarządzanie i handel zagraniczny w warunkach integracji. Materiały konferencyjne - Zarządzanie bezpieczeństwem
Ze wstępu: "Bezpieczeństwo jest w coraz wyższej cenie. Zajmują się nim naukowcy
oraz praktycy z różnych dziedzin. W najszerszym wymiarze
pojęcie „bezpieczeństwo” sprowadzić można do słów: stan niezagrożenia,
spokoju, pewności. Takie ogólne ujęcie problematyki bezpieczeństwa
sprawia, że różne podmioty podchodzą wybiórczo do tych bardzo
ważnych zarówno dla pojedynczych ludzi, jak i społeczeństwa zagadnień.
Inaczej postrzegają i interpretują bezpieczeństwo politycy, prawnicy,
ekonomiści, wojskowi, policjanci, lekarze, pedagodzy, a inaczej
zwyczajni ludzie. W ich ujęciu bezpieczeństwo to:
1) stan świadomości człowieka, w którym czuje się on wolny od
jakichkolwiek zagrożeń, pociągający za sobą poczucie spokoju i komfortu;
2) niczym niezakłócone współistnienie człowieka z innymi ludźmi
i środowiskiem przyrodniczym;
3) stan bez lęku i niepokoju o siebie i innych, pewność jutra;
4) brak zagrożenia utraty zdrowia, mienia i życia, komfort psychiczny
umożliwiający realizację życiowych marzeń i celów;
5) sytuacja, w której człowiekowi nic nie zagraża, a w nagłych
i nieprzewidzianych sytuacjach może liczyć na pomoc i wsparcie innych."(...
