I need to transform many pictures of an analog clock with only on pointer ( the one of hours ) in the corresponding numerical data. Is it possibile to do it with mathematica? I would like to find some documentation about this. Thanks in advance

Edit: You suggest to give an sample image (is not a clock is a dynamometer but is the same problem, I talk about clock to simplify) About the code I have no idea how to do it, this is why I am asking documentation. Sorry. enter image description here

    $\begingroup$ Can you give an example of the picture, and show what you have tried? $\endgroup$

    $\begingroup$ There is no clock and no code in the post, how we are going to start? $\endgroup$

  • $\begingroup$ I edit the post to give you an idea of the image that I have, about the code I have the code to analyze the data but I have no idea on how to take data from picture. $\endgroup$

  • $\begingroup$ Giuliano, is this picture of your experimental apparatus? If so, you might find some benefit in running ImageLines while focused in on the region of the meter. $\endgroup$

This has been discussed on the Wolfram Community forum:

One could also use the Python External Evaluation functionality and use existing OpenCV implementations for this problem, e.g., https://github.com/intel-iot-devkit/python-cv-samples/tree/master/examples/analog-gauge-reader
