Is it possible to modify the detectChec​kerBoard-f​unction to detect all edge points?

Hello,

I want to detect all edge points on a Checkerboard, which is not rectangular. I am using the Funktion: detectCheckerboardPoints

I need this to calculate the distortion on an Area.

Thanks for your answers!

Hi Matthias Ernst,

I understand that you want to detect edges in a checkered image which is not rectangular. The “detectCheckerboardPoints” function only works on rectangular images, you can use “edge” function from Image Processing Toolbox which can detect edges in non-rectangular images.

Here are few resources which I feel will be helpful in your implementation.

• Edge: https://www.mathworks.com/help/images/ref/edge.html
• Edge detection Example: https://www.mathworks.com/help/images/edge-detection.html#buh9ylp-13
• Edge detection with MATLAB: https://www.mathworks.com/discovery/edge-detection.html

Hope this helps!
