Digital Image Correlation – The basics

6 300x243

By Florent Mathieu, CEO of EikoSim What is digital image correlation? The Digital Image Correlation (DIC) technique is a non-contact, full-field measurement approach that enables the assessment of the deformation and motion of objects. This is achieved by comparing digital images of the object before and after deformation. DIC measurement is a technique used to…

How to make a speckle pattern suitable for Digital Image Correlation?

Aile Avion

Context: Speckle patterns & digital image correlation The principle of image correlation is based on tracking information from a so-called “reference” image in the following images, often called “deformed images.” When using digital image correlation (DIC), speckle patterns are created on the surface of a specimen to address uniqueness concerns. As a result, the accuracy…

Crash-test and image correlation: how to measure seat deformations and follow the dummy’s movements

Senza Titolo

Crash tests are crucial in developing and certifying products, especially for the automotive, aeronautical, and railway industries. These tests simulate collision or impact scenarios in order to evaluate the resistance and safety of products. Among the equipment used to perform these tests is the reverse catapult, which is a device that projects an object, in…
