Re: How to Validate Vehicle Number in Powerapps

Hi,

 

  1. in your case, you must use an OCR-Service: e.g.: microsoft cognititve services https://azure.microsoft.com/en-us/services/cognitive-services/computer-vision/#detect-text
  2. if you build/create an canvas-App, then you transfering the picture to the cognitive-service
    1. the response of this service is an JSON and you must parse like here #PARSEJsonFlow http://johnliu.net/blog/2018/6/a-thesis-on-the-parse-json-action-in-microsoft-flow
    2. this response JSON contain your vehicle-number

Re: How to Validate Vehicle Number in Powerapps

Can you please elaborate on requirements? Do you need to validate the string value for license plate for correct format string ? What is the correct format ? Or you want to use some REST service to check the number for existence ?

What about getting the string value at all - do you need camera and OCR ?
