recognize Number from Picture

[JonB]

What happened is that img returned none. If you put a try catch around that line, you can cancel in the case that there is no img.

[DavinE]

@JonB,

i Think you getting me wrong.
I wanted to try to set the picker.allowsEditing to False because when it's True on every img is a section for the img but i don't want this.

do you know now what i meant ?

[cvp]

@DavinE try with

    img = ObjCInstance(info)['UIImagePickerControllerOriginalImage']   
    #img = ObjCInstance(info)['UIImagePickerControllerEditedImage']   
.
.
.
        picker.allowsEditing = False

@cvp,
No, this works unfortunately not

[cvp]

@DavinE for me it works, it picks a photo and the analysis is immediate without passing via the window where you have to tap "use"

[DavinE]

@cvp,

I know why it doesn't work for me, he analyzes the image differently ... Unfortunately, the output is different for whatever reason!

So it would work, but unfortunately not an option for me 😊

But thanks for your help!

I'm having trouble following the conversation -- is the problem still that you are getting the NoneType error?

Try this in your delegate handler
infodict=ObjCInstance(info)
print(infodict)
print (infodict.allKeys())

(At least, I think that's how one gets the keys from a NSDictionary.. you might need a for loop)

There are a few possible key values that the info object can return. @cvp, maybe you know a better way if printing out all options ...

For me the problem has disappeared when I used original photo. in this case you can set the allowsEditing flag to False

my Problem is the Following one.

i get this output with that settings:
img = ObjCInstance(info)['UIImagePickerControllerEditedImage']
picker.allowsEditing = True

that is correct and i can work with it.

when i use the following settings:
img = ObjCInstance(info)['UIImagePickerControllerOriginalImage']
picker.allowsEditing = False

get i this:

i think the language is the Problem...

Thus you don't have anymore the error on img.ptr

[DavinE]

with your changes, no:

img = ObjCInstance(info)['UIImagePickerControllerOriginalImage']
picker.allowsEditing = False

only that, that the recognized Text makes no sense...

[cvp]

@DavinE did you edit the picked image? In this case, you don’t see the original image but it is still hidden in the edited image.

[DavinE]

@cvp,
It's for both Tests the same Image, and the image is Original nothing in it is edited.

[cvp]

@DavinE could you post in Imgur the image that does not give correct info with my code

[DavinE]

@cvp said:

Sure, here it is:

https://imgur.com/a/rbOtAg0

[cvp]

@DavinE that is the immediate result of my code after having picked your image, without passing via an "use" screen

1179629
3500670
3500156
3532239
1177739

With

    img = ObjCInstance(info)['UIImagePickerControllerOriginalImage'] 
.
.
.
def get_photo_action(picker_type,sender):
.
.
.
        picker.allowsEditing = False

Is that not what you want?

[DavinE]

@cvp,

i add more code into it because i want more Data from the Pic.

This is mine recognize Function:

and here it only works with the Edited mode...

@DavinE I guess that you recognize function has bugs because with mine, and

    img = ObjCInstance(info)['UIImagePickerControllerOriginalImage']
        picker.allowsEditing = False

I get all infos from your image with

def recognize(image_data):
        req = VNRecognizeTextRequest.alloc().init().autorelease()
        handler = VNImageRequestHandler.alloc().initWithData_options_(
            image_data, None
        ).autorelease()
        success = handler.performRequests_error_([req], None)
        if success:
            recognized_text = [
                str(result.text())
                for result
                in req.results()
            ]
            for txt in recognized_text:
               if 1==1:#len(txt) == 7 and txt.isnumeric():
                   print(txt)
        else:
            dialogs.hud_alert('Failed to recognize anything')

With OriginalImage, Your code hangs if I do not skip these lines

                                    print('here')
                                    continue
                                    if console.alert('Objektnummer Fehler ?',f'Die Angabe welcher in dem Objekt hinterlegt ist unterscheiden sich:\nAktive Nr.: {orderConfirmation}\nNeue Nr.: {[int(temp)for temp in txt.split() if temp.isdigit()][0]}',hide_cancel_button=True) is 2:

That was my mistake.....

you need to add: @ui.in_background
like that:

    @ui.in_background
    def recognize(self, image_data):

then it works and you see i get nothing as a result in my array only with the Edited Mode
