Azure Computer Vision OCR with Power Apps and Power Automate
HTML-код
- Опубликовано: 1 авг 2024
- I put together a demo that uses a Power Apps canvas app to scan images with OCR to convert to digital text. This calls the Computer Vision API in Azure Cognitive Services to process the image. The Power Apps canvas apps calls a Power Automate Flow to make the call to Azure.
This demo works not just in our commercial cloud, but also Azure for Government and O365 GCC High which is Microsoft's US Government FedRAMP High compliant cloud.
Sample solution file and setup notes for this demo can be found on GitHub below,

I think that was the problem the environment I used my Mac! when I switch to windows it works thanks for your helping. Regards and all the best in your useful channel
Glad you got it all working! Thanks for following up.
@Steve Winward, great demo, i was following your recommendation but got a bad gateway error, even it is showing the power app is connected to the Flow , I am using the same environment as well. any recommendation?
I put together a video on how to setup this demo. Have you seen it yet?

@@SteveWinward it is working, I had to redo that connection set up according to our environment!
around 3:50, he skips over the part of the flow called 'Remove_the_Header_Info_from_the_Power_Apps_Image_Value'. On my end, it's failing with an error "The 'start index' for function 'substring' must be equal to or greater than zero and must be less than '0' which is the length of the string." Since I just updated the API key and end point within the flow and updated the Power App, what's causing this?
Nice video. I'm curious how this solution would handle images with data stored in tables and images. . E.g. invoices .
In the Power Platform there is also a feature called AI Builder that has a Form Processing model and a pre-built Invoice Processing model that would probably handle those scenarios really well.
@@SteveWinward thanks so much for the swift and detailed response I'll do some reading up on it. Please keep the videos coming. This is great stuff 😎
@@miscellaneouslyric thank you!
Thanks for this Video and solution, but when I try to import it in power app I got this error message:
The solution file is invalid. The compressed file must contain the following files at its root: solution.xml, customizations.xml, and [Content_Types].xml. Customization files exported from previous versions of Microsoft Dynamics 365 are not supported.
could you help me please to solve that
Take a look at the install instructions I put together on GitHub. Let me know if this works for you.

Also. Here’s a video I made showing how to import the solution file.
ruclips.net/video/PKi5KePZ1us/видео.html
yes I followed the video and the link, this error from the import step
Ok. Sorry you are getting that error. I will look into this later to see if the latest file I uploaded has an issue with it.
I just imported the solution file into a new environment and I'm not able to reproduce the issue you are experiencing. What kind of environment are you trying to import the solution file into?
