Marker based AR with SRWorks?

Hi,

 

I wonder if it's possible to make Marker based AR app with SRWorks?

If so, do you have examples or suggestions about the implementation? (like get the camera images, identify the marker and find out its position(not sure which camera parameters should I use, the distorted or undistored ones) in physical space then generate virtual objects according to the physical position of the marker in the two image planes that display camera images)

I'm using Unity.

You need to use undistored  image for marker detection.

You could refer to the chapter 2 of this book to get the idea of implementation, https://www.cs.ccu.edu.tw/~damon/photo/,OpenCV/,Mastering_OpenCV.pdf.

Thanks for reply. I found that Cx and Cy are already provided, but are fx and fy also available? And because the undistored image is available, so I can set the distortion coefficients as 0 right?

Thank you.

SRWorks has moved Cx and Cy to the center of undistorted image. Focal length is provided as well, where fx=fy.

yes, distortion coefficients is 0.
