Hi @ryan ,

So we have an example of a 4-point transform, but not yet for the matrix transform:
https://github.com/luxonis/depthai-python/blob/ed6c07f/examples/20_color_rotate_warp.py#L140

And here is the call for the 3x3 transform:
https://docs.luxonis.com/projects/api/en/latest/references/python/#depthai.ImageManipConfig.setWarpTransformMatrix3x3

We haven't written demo for it yet though. I -think- if you run the OpenCV calibration you should be able to get this calibration and then use it though, which then I -think- will do something. But ultimately you would want the multi-point mesh.

Thoughts?

Thanks,
Brandon

Hi @ryan ,

I was wrong on this. We do actually have support for WARP/DEWARP as it's own node in the ImageManip node.

It supports 4K input now, but a max of 1920x1080p output, and is limited to a 3x3 transform, and fisheye would need the addition of multi-point mesh support. It looks like we can increase this limit to 4K output as well, we will just need to check on the resource allocator to allow it to use more resources for 4K.

And it looks like we can enable multi-point mesh for this fisheye dewarp. This is already an option in the stereo node I think (enabling mesh calibration).

Will circle back with more details. In the meantime, you could try out the 3x3 transform config warp/dewarp to see how it does. I'll see if I can figure out how to do that. :-)

Thoughts?

Thanks,
Brandon
