Yes, obviously you’d need better photos than what I supplied. My apologies I’m not sure how I didn’t realize that before posting the question. I have gone through an updated the image with a much clearer screenshot of the test setup.
Thank you for the “homography” idea. I recognized that this was an issue, but only put around 20 minutes into testing solutions for this before moving on. I will go back and attempt to adjust the input image to be more rectangular and not skewed.
As for your question about the layout, yes it will remain the same. The labels & values will change (although I don’t care about the labels, only the values) but their position should remain consistent within a very small margin or error. Consequently, manually defining the regions is exactly what I do.
