Hi,
I'm trying to use the new RecognizeDocumentsRequest from the Vision Framework to read a receipt. It looks very promising by being able to read paragraphs, lines and detect data. So far it unfortunately seems to read every line on the receipt as a paragraph and when there is more space on one line it creates two paragraphs.
Is there perhaps an Apple Engineer who knows if this is expected behaviour or if I should file a Feedback for this?
Code setup:
let request = RecognizeDocumentsRequest()
let observations = try await request.perform(on: image)
guard let document = observations.first?.document else {
return
}
for paragraph in document.paragraphs {
print(paragraph.transcript)
for data in paragraph.detectedData {
switch data.match.details {
case .phoneNumber(let data):
print("Phone: \(data)")
case .postalAddress(let data):
print("Postal: \(data)")
case .calendarEvent(let data):
print("Calendar: \(data)")
case .moneyAmount(let data):
print("Money: \(data)")
case .measurement(let data):
print("Measurement: \(data)")
default:
continue
}
}
}
See attached image as an example of a receipt I'd like to parse. The top 3 lines are the name, street, and postal code + city. These are all separate paragraphs. Checking on detectedData does see the street (2nd line) as PostalAddress, but not the complete address. Might that be a location thing since it's a Dutch address.
And lower on the receipt it sees the block with "Pomp 1 95 Ongelood" and the things below also as separate paragraphs. First picking up the left side and after that the right side. So it's something like this:
*
Pomp 1
