Measurement and Imaging in Mechanical R&D

Field measurements are increasingly used in engineering, and more particularly in Mechanics. This module aims to present the basics of different imaging methods using image interpretation models of increasing complexity.

We begin by defining the principles of operation of imaging devices, then we present some tools of mathematical morphology in order to extract statistical information on quantities of geometric nature.

The methods of infrared thermography are then discussed through two models of interpretation: the calibration of the camera and the inversion of the thermal problem to access the heat sources.

The course ends with a comparison between experimental measurements and a numerical model by implementing a method of recalibration of finite element model.Theoretical courses are supported by practical sessions to implement the processing methods and illustrate the influence of the main parameters of analysis.
