Inference on pictures instead of videostream with Coral Camera on EdgeTPU dev board #14

Closed EspenTeigen closed 5 years ago

Hi.

I want to run classification inference on pictures triggered from a digital pin on the dev board. But i cant figure out how i can take one picture and send it to the tf-model with the gstreamer library.

Take a look at this example project: https://github.com/google-coral/project-teachable which does something almost exactly as you describe. Basically in the callback triggered by a particular frame from gstreamer you can check the GPIO status of your desired pin and then take an action depending that state - e.g. save the image or do whatever. If you want to avoid triggering multiple consecutive frames (say it's a button you want to press to take a picture) you may have to debounce the button state and detect the up or down edge by saving the previous state somewhere.

Thank you so much.
