Shearography and thermography are two well-established nondestructive testing methods. Yet, both methods present high subjectivity in the interpretation of their results, which difficulties the automation. Many efforts go towards applying intelligent

Carbon fiber reinforced plastic (CFRPs) is a composite material that has substituted metal alloys in many industrial fields. Non-destructive testing techniques are interesting inspection methods for the integrity assessment of composite materials and

Image-based industrial non-destructive testing techniques are commonly used for assessing material integrity. The cameras used for these tasks have lenses that can present form deviations, promoting anomaly creation on the acquired images. This probl

Applications of Digital Image Processing XLIII.
Composite materials have mechanical behavior comparable to metallic alloys, with the benefit of being lighter. However, due to their anisotropy, integrity characterization of impact damages remains a challenge. Non-Destructive Testing (NDT) methods a

Optical Measurement Systems for Industrial Inspection XI.
While industry 4.0 thrives, the needs related to three-dimensional assessment of industrial products growths in complexity. Frequently, this complexity cannot be achieved by one single sensor without outstandingly escalating procedural expenses, whic

Carbon fiber reinforced plastics (CFRP) are composite materials which are an interesting alternative to metal alloys in fields such as oil, aerospace, automotive, since CFRP have mechanical properties like metals but with a fraction of their weights.

Electric motors are subjected to many different quality control tests during their manufacture. Some of these tests are typically performed by human operators. It is well known in the literature that these operators are not reliable for repetitive in

There are many sources of faults during the assembly process of induction motors and most of them are related to the stator. In industry, electrical tests are typically performed, but some defects cannot be detected by such tests and the motors still

This paper proposes the use of image fusion for merging pulse-echo ultrasound and vibro-acoustography data of a metallic sample with machined damages employing algebraic, Boolean, and principal component analysis fusion methods, to enhance the measur
