Multivariate Analysis of Transient State Infrared Images in Production Line Quality Control Systems

Abstract: Manufacturers would like to increase production volumes while preserving the high quality of their products. The long testing times can cause a bottleneck of production processes especially taking into account the observed tendency for testing all produced devices. The main aim of this work consists in the analysis of time changes of features extracted from thermal images using the multivariate approach. The paper shows that if the principal component analysis (PCA), belonging to multivariate methods, is appli… Show more

“…The paper showed that if the principal component analysis (PCA), belonging to multivariate methods, is applied for quality control based on infrared images, then the minimum testing times can be estimated. In particular, a detailed temporal analysis for an exemplary production line has been carried out, and future perspectives were given, too [25].…”

“…Therefore, by considering all these observations and assuming that the head is an ellipsoid-like 3-D solid object, a PCA-based algorithm is designed for MSP extraction. PCA is a fundamental and prevailing statistical technique also known as Hotelling transform substantially used in digital image processing for data dimension reduction [34], feature pattern recognition [35], quality control [36], data decorrelation [37], data compression [38], and segmentation [39]. It is also acknowledged as a low-level digital image processing tool for tasks such as the orientation assessment and alignment of particular shape objects [40,41].…”

“…An automatic production line is an important part of the manufacturing system in the modern industrial field owing to the enormous advantages of high yield, good product quality and labor cost saving [1][2][3]. However, due to the variety of machine, complex layout and structure, any machine failure may lead to the whole production line shutdown, resulting in enormous economic losses to the production enterprise.…”
