Hi Community,
I have an idea for an app that I would like to scan a scar license plate from a mobile device and input that into a powerapps field. Would the forms processor work for this?

Thanks,
CT

Hi

I don’t think form processor is the right model for this. It would be a lot easier to use the inbuilt Text Recognition (OCR) model. https://docs.microsoft.com/en-us/ai-builder/prebuilt-text-recognition

You will need to collect the image in a Power App, pass it through Power Automate and the Text Recognition model, the return the output from the model to the Power App.

That should work, and no need to build your own model!

Please Hamish, tell me how you've been able to trigger a Power Automate Flow from within a Canvas App??
I've been trying to do so for a while for similar scenarios and I get errors when trying to connect with the flow in the App.

Hi @ZePowerDiver ,

Good point, I haven't actually built this before. I've just tried to do it but I am unable to get my Power App to connect to the Flow either. The problem being that the Flow must be inside a Solution to use the Common Data Service (current environment) connector which contains the Predict action to use with AI Builder. However, when I build a Power App within the same Solution I do not see the option for Flow under the Actions tab of the Power Apps maker. If I build the Power App outside of the Solution then I see the Flow action button but it cannot find my Flow within the Solution.

Is this the same thing you are experiencing?

What a pain!

An alternative work around would be to....
Take the picture in the Power App and save it to an entity (e.g. Note) in CDS
Then use an automated Flow to trigger on the record in CDS being created
Run the predict action and save the result back to CDS
Get the Power App to show the result from CDS
Not an elegant way to do this but that should work 😕

Hamish, that's exactly my problem and why I was wondering how you resolved this out!
Good workaround idea using CDS entity.. like you say not elegant and time to process may not be so great, but good thinking!!

@ZePowerDiver , I have just created an Idea for this so hopefully Microsoft can add this feature. I would be surprised if this is not already on the road map. Vote up! 😃

Hi @HSheild, @ZePowerDiver,

The AI Builder connector is now available for flows outside solutions. You can now create a flow outside a solution with an AI Builder action and call that flow from a canvas app.

I hope this unblock some of the scenarios you were thinking on building. 🙂
