A method of characterizing a part including obtaining an X-ray tomography image of the part and then a step of correlating the image with a reference wherein the correlation step includes searching among a predefined set of X-ray tomography image transformations for a transformation that minimizes the difference between the image and the reference in order to characterize the inside of the part.

Method for characterising a part

Disclosed is a method for measuring movement and/or deformation of a study part subjected to an external stress, the method implementing a color digital image acquisition device and image correlation unit. The method includes: acquisition () of a plurality of color digital images of the surface of the study part by way of the color digital image acquisition device during the application of an external stress on the study part, and processing () of the color digital images acquired in the step of acquisition of a plurality of color digital images so as to highlight contrasting details on variable scales.

Multi-scale method for measuring the shape, movement and/or deformation of a structural part subjected to stresses by creating a plurality of colorimetric speckled patterns
