MLKit Barcode Scanning - Accuracy

[randy-johnson]

Hello All,

I am using the capacitor-mlkit in an app I am creating for scanning code39 barcodes.

I am having trouble getting accurate scans using the plugin.

I have tried a few different barcode apps to test my barcodes and the other apps are getting accurate scans.

I have been through the plugin docs, but I am not seeing anything that I could change to help the accuracy.

I am looking for some advice on how to proceed.

Also I have tried this on IOS and Android and they are both suffering from the same issue

fwiw, I gave https://github.com/capacitor-community/barcode-scanner a whirl this evening and it works every time.

I also tried https://github.com/robingenz/capacitor-mlkit-plugin-demo wondering if perhaps it was something in my implementation and I had bad results there too.

The scanned barcodes are processed by the ML Kit library, the plugin only serves as a wrapper. You should therefore report your problem in https://github.com/googlesamples/mlkit. There are tips to improve the real-time performance but this only affects the real-time performance. If you also have the problem with the readBarcodesFromImage(...) method, then we cannot do anything about it.

fwiw, I gave capacitor-community/barcode-scanner a whirl this evening and it works every time.

You get different results with capacitor-community/barcode-scanner, as a different library is used there to process the barcodes.

Hi Robin, ah yes, that makes sense. I will reach out there.

If you also have the problem with the readBarcodesFromImage(...) method, then we cannot do anything about it.

Are you suggesting that I try using readBarcodesFromImage() to see if the problem exists there too?

Yes, exactly.
