A free 2D & 3D DIC (digital image correlation) software

Tue, 06/30/2009 - 22:20 — Admin

Thank you for your patient. Here is the newest version upgraded on June 11, 2010.

[You must login first to see the software] 


This software contains lots of robust functions for image analysis and processing, deformation, shape, and motion measurement. However, since most users are interested in DIC, the videos below show only how to use DIC. Please be noted that the menu in the newest version is slightly different from the one in the video. Opticist.org needs your comments and input to make this DIC program better. 

The software is developed with Visual C++ 2008, you may need the following Visual C++ 2008 Redistributable Package to run the program. http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf&displaylang=en

Here are two demo video clips of the software.

2D DIC

Hi.The results i.e displacement or strain computed by 2D-DIC method are saved as dat files.How to reload the saved results if I reopen the program?These dat files aparently cannot be readed by the program.Please help me,thank you.


how to change the font of the number in the color bar??

  i work with website

 

i work with website designers london as a web programmer. I have given some
task which requires software that has some unique featurees and it also
requires use of DIC. I have faced some problems in using DIC bt the video which
you provided here are great and explains how to use DIC. I found your software
very useful for my work due to its enhanced features. This software has lots of
good features for image analysis and processing, deformation, shape, and motion
measurement. I am going to use these software to complete my work and hope it
will be appreciated by my seniors.

3D DIC help

I am trying to perform 3D DIC with this software. I have tried opening two ref files and two def files and applying 3D DIC as the pictures are taken from two cameras simultaneously. I keep coming up with this error:


"Cannot open camera calibration file! DIC 3D calculation will not be applied."


I am practicing with sample pictures and do not know how to obtain a calibration file. Also, it seems the tutorials/youtube vids are used for 2D. Any help?

Mon, 08/09/2010 - 16:38 — phuocminhvo

3D DIC

Hi there,

It seems that you haven't calibrate the camera before performing 3D DIC. In order to calibrate the camera, go to Tools, click Camera calibration. The obtained parameters can be found by going to Tools-> Check/Edit parameters-> CC22.

Currently, you can only calibrate the camera by using checker board pattern. We will release a newer version which can handle circular pattern.

Sincerely.

3D DIC Help

Every time I try calibrating using the checkered pattern I encounter a debugging error. Also going to the check/edit parameter>>CC22, it opens the blank .txt notepad file. What is the next step?

Sat, 08/14/2010 - 22:39 — phuocminhvo

3D DIC help

We've never encountered such an error. However, I think the problem lies either in the parameters that you input or the quality of of the checker board that non of the corners can be found. For the parameters, you need to enter the number of inner corners in a row and a columm.

Tue, 08/24/2010 - 14:47 — staubin2

Calibration Error

The calibration seems to work ie. the program finds all the inside corners for rows/columns. An error still comes up (Microsoft Visual C++ Runtime LIbrary, Runtime Error!. It says This application has requested the Runtime to terminate it in an unusual way. Please contact the applications support team for more information>)

2D DIC

Hi there,

We haven't released the complete tutorial for this software right now. However, here are the steps to perform 2D DIC.

1. Go to File -> open the undeformed and deformed images.

2. 2 ways to create a boundary image :

  • simply use the boundary tools (line, rectangle or ellipse) located in the left side
  •  go to Image Analysis->Ease Whole Image-> boundary tools-> right click to add initial image->draw your choose boundary->right click to clear initial images-> save that image as the boundary.

2. Go to Other Analysis->  #4, DIC method-> 2D DIC.

3. In the Boundary option in the pop out diaglog, Load E/B From An Image if you want to use the saved image that you created by the 2nd way in step 2 or Use Current E/B in the images if you want to follow the 1st way.

4. Choose other options in the above dialog as you wish.

After click OK, you are ready to get the result.

Sincerely.

When I use the second way to creat a boundary image,I went to Image Analysis->,and I cannot find Ease Whole Image option and the other following buttons.Thers is just a Erase Whole Image,and Ease Whole Image doesnot exsit in the Image Analysis.I use the Vesion 0.940.How to add initial image?

Problem using the software

Hi there,

I don't know if there are issues about our software but one common way to fix your problem is that you may open it as adminstrator.

I hope my reply can solve your problem.

Sincerely.

about accuracy

Can you tell me your software's analysis result accuracy when use computer simulated speckle images?

Mon, 06/14/2010 - 01:18 — Admin

Re: about accuracy

The accuracy depends on the deformation field of the simulation. It can be perfect for integer-pixel-shifting case; meanwhile, the error can reach 0.01 pixels or larger for other cases.

How to analysis a series of images at the same time?

Hi,

In the vedio, there shows only a way to analysis two images - refrence one and deformed one at the same time. Is there a way to analysis a series of images - one refrence image and many deforemed images at the same time? I think this is a practical way to analysis the displacement and stress.

Thanks
Jingcheng

Mon, 06/14/2010 - 01:03 — Admin

Re: How to analysis a series of images at the same time?

Just open all the images, and put the reference image on the top.

Reference to this work

Thank you for the open source program. It is very rare to see a DIC freeware on the net. May I know how would you like your work to be referred? Have you got any paper that we can refer to, regarding this software? Thank you.

exporting data to 2D array

Thank you for the awesome software. However, I can only view the displacements and strains as an image with a color scale, as demonstrated in the videos. I was wondering if there is a way to view/export the data to a 2D numerical array format, such as a dat or excel file.

Any help is much appreciated!

After the analysis, click

After the analysis, click "Save Disp/Strain Data" under "Displacement & Strain". "Common" format is ok.

Just added the help document.

Just added the help document. The document is a little bit old (mainly for interferogram analysis); and it is converted from VC6.0, so there might be some problems. For DIC, please refer to the video. We will update the help document very soon.

hi,

Thanks for your useful software.

I want to know the date of uploading of new version?

Tue, 04/13/2010 - 07:15 — 83626320

It's April 13th already

…………
I have already been waitting for the new version for half of a year.

Wed, 04/14/2010 - 18:03 — crxsirg

Just a suggestion...

Just a suggestion, you could try coding your own program. It's tedius but you'll understand the methodology much better after doing it.

Thu, 04/15/2010 - 05:14 — 83626320

I tried...

My background is mechanical engineering. I did tried to program it by myself last summer vocation, and it was a totally mass.

Wonderful job

This software is useful for me to analysis the result of our experiment. Thank you for sharing.

I have some questions on it though.

1. Dose the MAX displacement mean the sum of the vectors? Are there separate displacements of x and y directions?

2. For two pictures, for example, "1.bmp" is the refrence one, the other "2.bmp" is the deformed one. So why there are two displacement contours separately in two window? I think there should be only one result.

Sincerely

Stone

Sun, 03/28/2010 - 21:50 — phuocminhvo

Hi,

They are the X and Y components. That's also the reason we have 2 windows

Release the source code

Thanks for the wonderful job! I'm wondering if it is possible to release the source code. I'm trying to implement my own image correlation code in Matlab, but stuck at the bicubic interpolation.

Fri, 04/02/2010 - 14:29 — crxsirg

hey rz_ca,

I'm actually doing the same thing using Matlab. I'm still composing my program, but for the bicubic interpolation I used the formulation from wikipedia (just type in bicubic interpolation), part of which comes from the book Numerical Recipes in C++. I also looked to Dr. Sutton's paper "Digital image correlation using Newton-Raphson meathod of partial differential correction."

Batch mode - Help files - Admin account

Hi,
The program works great - Thanks for putting it out there...
Comments:
It would be great if one could set up a batch refinement of a series of pictures using the same region and parameters
Help files would be nice. What is the unit of the strain? Looks like it is 1/1000?
Why does it have to run in an admin account?
Thanks,
Bjørn

Help files?

Hi guys,
What happened to the help files? I downloaded this a while ago and it had help files. Now I have a new workstation and the new version comes with no help at all. It says below that you are updating them, but with none the software is nearly useless! Anything would be good!

Can you send me the old ones directly?

how to program DIC

Hi, I would really like to program my own DIC package but I'm honestly stumped as to how to begin searching for a deformed subset? . I understand you may be refraining from releasing the source code until you compose help files, etc., but is there any way you could provide some code snippets to get some of us started like me. Thanks

Tue, 03/09/2010 - 22:28 — Minh Vo

Hi, The algorithms simply

Hi,
The algorithms simply like this:
-You create a subset of the reference image,in my case we make it default at 29x29 pixel.
-Use the correlation formula in this paper :"Two-dimensional digital image correlation for in-plane displacement and strain measurement: a review",which you may want to look at, to find the center of that subset in the deformed image.
-Jump to other subset and redo step 2.
Then,you should have the displacement field of deformed images.
