[ostwalankit]

Step 1: Describe your environment

• Android device: _Google Pixel
• Android OS version: 9
• Google Play Services version: "com.google.firebase:firebase-ml-vision:19.0.2"
• Firebase/Play Services SDK version: _____

Step 2: Describe the problem:

I am not able to scan PDF417 barcode on south african driving license (attached below) . It dosent scan anything. I am using default mlkit project of github. I have added Firebase to the project.

Following are dependencies used.

// ML Kit dependencies
implementation 'com.google.firebase:firebase-ml-vision:19.0.2'
implementation 'com.google.firebase:firebase-ml-vision-image-label-model:17.0.2'
implementation 'com.google.firebase:firebase-ml-vision-face-model:17.0.2'
implementation 'com.google.firebase:firebase-ml-model-interpreter:17.0.3'

Steps to reproduce:

1. Load the project ML kit.
2. Select Java ML Kit
3. Select Live Preview Activity
4. Select Barcode detection from spinner at bottom
5. Now scan the south african driving license.

Observed Results:

There are constant recurring logs.

2019-02-28 21:10:34.172 3508-3746/com.google.firebase.samples.apps.mlkit D/skia: onFlyCompress

Expected Results:

Scan the PDF417 barcode and show appropriate result in context to it. I scanned the same driving license via. Microblink app and it scans perfectly.

Relevant Code:

Used the mlkit code on github.

I am able to reproduce the same thing using my California driver's license. And I can confirm that other barcodes, like QR codes, scan in the app.

Let me report this to the ML Kit team.

I am also experiencing similar issues with license PDF417 scanning. When scanning an Ontario Canada license it will return the result as TYPE_TEXT instead of the expected TYPE_DRIVER_LICENSE, and will not be encoded properly.

Hi! Any update on this? Same issue with argentinean license

[sybrin-innovations]

Hi! I am also curious to see if any work has been done on this.

What i have seen is it works on older SA driver license not newer ones.

Not sure if its a change in the PDF417's that's not catered for in ML kit

same issue

Tested PDF417 decoding (US DL) from camera feed and it was not working at the beginning.
I had to raise the picture resolution (switched from 480x360 to 1280x720) to make it work. Did you try increasing the picture resolution?

[ostwalankit]

YES, BUT IT STILL DIDNT WORK FOR ME. CAN YOU SHARE YOUR IMAGE, SO I CAN TRY SCANNING IT AND SEE IF ISSUE IS RESOLVED. THANKS

I am facing the same issue as described above for the new Florida DL.

Almost one year that this bug was reported but there is not a feedback from firebase_ml_vision team.

Please, this feature is really important for us. Thank you

So i managed to get the DL scanning using image processing. This is not the best solution as it reduces the speed of the capturing process significantly.

The Issue i am speculating with the DL above is basically FB is looking for the Start and End but can't find it.

@ANY FIRE BASE ADMIN. I would love to test this out. Is there a way i can pull the PDF417 code?

I am sure this will help a lot of people.
