Can you please past here the code you change?

IPrototypeI commented 6 years ago

I changed the code recognizeWithCountryRegionNConfig("us", "", image.getAbsolutePath(), openAlprConfFile, 10);

To

recognizeWithCountryRegionNConfig("eu", "", image.getAbsolutePath(), openAlprConfFile, 10);

So only the parameter us to eu do you have any suggestions ?

@IPrototypeI Can you try taking the picture in landscape mode. For me, it only does recognition on landscape pictures and not on portrait. @SandroMachado Is this by design? Is it possible for the app to recognize plates from portrait images by changing the config file? Thanks

@umair-io @IPrototypeI If the issue is only while taking pictures in portrait mode for you, there is a known bug with the MediaStore.ACTION_IMAGE_CAPTURE on some devices where the image is rotated after being taken. If an image is rotated incorrectly before being fed into OpenALPR, you will not get proper results back.
