Openmv RT1062 - Character Recognition

Hi all,

We’re working with the OpenMV RT1062 camera and want to run a TFLite model on it to recognize A–Z letters and 0–9 digits (total 36 classes).

We’re just starting out and were wondering:

  • Are there any pretrained TFLite models available for character recognition (A–Z, 0–9) that are compatible with OpenMV?
  • Any example code or tips on how to run such a model with the OpenMV tf module?

Any leads on this — models, datasets, training tips, or working examples — would be super helpful!

Someone did some of this: Digital Character Recognition on Electric Meter System - OpenMV Cam H7 | Expert Projects

As for examples, you can use edge impulse to train a net that does this. You just need to upload all the pictures of digits, label them which can be done automatically, and then you can train a net pretty easily and they output the sample code to run it.
