Digital Image correlation

 

Digital image correlation (DIC) is a measuring technique of full-field displacement and deformation measurement at the surface of any object. We developed the first open and fully customizable image correlation platform.

Holistic approach provides direct access to variables and parameters which influence DIC performance.

More, this application is opened for bidirectional integration by using external scripts.

This  DIC platform is fully modular, including components for image deformation, performance optimization, error assessment, material identification, model validation, and many more.

All of this make our application the most complete and the most versatile system available today.

PRODUCT RANGE (DIC) :

  • providing complete solution : hardware and software with installation and training
  • if you already have video equipment (video camera, lenses, lights), you can purchase final or annual software license only.

Multi camera module

Materials characterization (VFM: virtual fields method)

Structural validation of Finite Elements simulations (FE-VAL)

 


LIMIT OF TRADITIONAL SYSTEMS

  • Problem of tests repeatability as soon as there is result changing
  • Modification of the result when parameters are changed
  • Difficulty in determining result accuracy
  • Difficulty in general understanding of result value
  • Difficulty in reusing data
  • Difficulty in comparing data
  • Difficulty of rebuilding non-elastic strain constitutive laws


So we have worked on the development of a platform to overcome these constraints and difficulties in order to offer:

  • an easy understanding user interface
  • reuse of experiment, selection of parameters, possibility of using the non-expert system
  • calibration simplicity and flexibility
  • validation of experimental configuration
  • our absolutely unique performance module


To complete analysis, identification or materials characterization, we developed virtual fields method, perfect transition with modeling and simulation to models structural validation.


This approach of quantified validation is absolutely unique.


The entire platform can then be enriched with the universal programming interface. Generally, each entities has its own preferences, its own methods, so its own scripts to handle tests, compare results, draw charts...


Today, it is highly difficult to interfere with existing systems, either to add variables or extract data. Our platform allows engineers to use any programming or scripting language, to be able to create a bidirectional interface with the entire platform.


This platform structurally simplifies DIC approach, makes it universally open for any interaction, language independently, and allows engineers to add their own scripts, do their own post-processing, put their own additional variables into the system, and quickly and easily develop their features.
