Would it be possible to post one of your calibration images to this issue so I could check that you have the right parameters? (You have the link to your drive folder above, but it's all .zip files which I don't want to download)
Also, I would use a more recent version of DICe. Here's the latest: https://github.com/dicengine/dice/releases/tag/v3.0-beta.8. This will have better calibration routines.
Hi, thanks for the reply.
Here is the photo.
If you want photo series, I reload them on the google driven without .zip https://drive.google.com/drive/folders/1-AK0pFf6tqTYE1GkEMbz17EXMHSRWXLw
I have also tried the new version. I have one more question about the new version. Where can I add the desired tracking point?
I mean this funktion>> add live plot pt
have a nice day! :)
Looking at you cal images, it seems you only have images with the calibration target lying on the table. To get a good cal you need images with the calibration target tilted at different angles (in and out of the plane of the table).
For the live plot points, once you select the button you have highlighted above, you just click the location in the image where you want the live plot.
Thanks for the advice. :) I try to make the camera on the camera stand, keep it fixed. And the cal. target on a plate and make the in and out of plane. But unfortunately it donsent make the results better.
-another question beyond cal.____ There is no large surface on my object. It is a cross pattern with small area, aprrix. 1.2mm*50mm. Is DICe suitable for it?
or should I use the same small cal. pattern for calibration?
and in the new version, i cant find the button for 'add live plot pt'. Colud you please help me.
Have a nice day!
Making the dots bigger would help since the calibration depends on the center of the dots which gets averaged from the pixels that the dot covers. The distance shouldn't be a big deal, but not being able to angle the cal target towards and away from the camera will likely limit the quality of your calibration. The size of the sample is not really a problem, but making sure that the speckle pattern is at least roughly 3 pixels for the dark and white patches will lead to better results.
Hi guys, it would be great if you could help me with this issue. Many thanks in advance for your time and investment.
I am trying to calabriton my DICe with the symmetric dot grid with special corner dots.![image](https://github.com/dicengine/dice/assets/170955297/496f9a1e-a8cf-4158-9f3b-fe011e618ead)
There are some querstions from my seite:
DICe version: DICe_setup_v2.0-beta.16-win32-x64 Camera.6960 3904 Pixel Inspected object: 50mm 50mm Targeted deformations: 1mm
And the .xml it is in the attachment. DICe-Output.zip There is the link of figures for calibration: https://drive.google.com/drive/folders/1-AK0pFf6tqTYE1GkEMbz17EXMHSRWXLw?usp=sharing
I have tried many way but unfortunately not successful. I will be great helpful if someone can give me some suggestions and inspirations. :) If you need more information, please let me know. Thank you!!!
