Has anyone run into the plateOutline not showing? - I tested this on ios

App showed the camera for 1sec then crashes for both scenario:

1. Followed the instruction on README.md to test on the new project did not work.
2. Git cloned the example and follow the instruction on README.md still not working

Help please..

Hi - had a project that would build last night - then I upgraded to XCode 8.3, now I get this error:

Any idea how to resolve this?

Hello,

I've been trying to make this library work on Android. It seems to be working fine on the real device, but when I am trying to launch it from android emulator, whenever I open up the camera, it crashes after 1-2 seconds. I've linked everything using instructions. I've also added camera permissions. Copy-pasted code from the README. Does anyone have any clue what could be wrong here?

I am trying to test this pull request.
I have completely implemented all the steps in doc pull request and I get this error on step 4.
@JohnYangSam

Could you please give example for version 1.1.0. Because we start our app and we see white screen. We done all steps for setup react-native-openalpr. Camera not start and dont ask permission for camera.

A few months ago we reached out privately to a few people to see if anyone wanted to take over this project, because it is no longer used at CarDash and all contributors to the project have since left the company.

We didn't get a definitive answer at that time, so I am now reaching out to all prior contributors: @emrosenf @friendly-robot @samcorcos @RobertSasak @JohnYangSam @Hunsu are any of you willing to inherit this repository? (It will require deleting your own fork of the repository and then I transfer this repository to your account.)

If there is no interest from prior contributors to maintain this repository by Christmas, I will be archiving the repository and hopefully one of the forks survives as the de facto continuation of this project. To avoid an Event-Stream-like security situation I will not accept transferring this repository to anyone not mentioned above.

The image shown is not correct for rotations UIDeviceOrientationPortraitUpsideDown, UIDeviceOrientationLandscapeLeft and UIDeviceOrientationLandscapeRight. It is only correct when the view is in UIDeviceOrientationPortrait.

Hello,
there is this line in the docs:

if (confidence > 0.9) {

but when I log confidence I get a number between 1-100. The correct check should therefore be:

if (confidence > 90) {

I understand that higher resolution images will not necessary improve the licence plate recognition. More over it would use more CPU.

Instead of resizing image down to 480x360 I would like to crop the center of the image to size 480x360 (Camera.constants.CaptureQuality.medium). User of the app will be instructed to point camera in such a way that a licence plate is in the center of the image.

This would allowed to recognise licence plate from much longer distance.

I'm not sure for which version of react-native this has been implemented, however, I noticed in index.js PropTypes is imported from 'react' when in newer versions it's become its own module and should be imported from 'prop-types'.

https://www.npmjs.com/package/prop-types

I hope this helps,
George.

How to add new license plates for different cities or states for a specific country?

The current color is blue; let's change it to hot pink so it sticks out more.

Hello, thanks for this lib, great job!

When compiling my react native project using country="mx", the camera don't work, literally if I change to 'us' it works, rarely enough if I use the live reload tool and change it to 'mx' (compiled in 'us') it works as expected.

So the issue, unable to compile using another country than 'us'.

And it breaks in this line of code on xcode project.

Thanks in advance

Hello,
I installed openalpr on both versions, iOS is running very well but on Android I have a very high lag (I use a Samsung S7), delayed reading ... is there any config for this? A screenshot if the number is the one I'm looking for how can I do? I saw that the camera module is not really the camera... Thank you, I am
waiting for your answer

Hi,

Today i tried use this project in my android application. So i followed all installations instructions step by step. But i'm getting the following error:

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':app'.

Could not resolve all dependencies for configuration ':app:_debugApk'.
Configuration with name 'default' not found.

So, i downloaded the example and did the usual:

• downloaded the example project
• run 'npm install'
• run 'react-native run-android'

and after that i'm getting the same error.

I don't know why this is occurring.

i'm using a MacOs operational system.

It takes around 8s before component show for the first time on iOS. UI thread is frozen and after 8 seconds camera show on the screen. Any following showing/hiding camera is very fast.
Has anybody else similar issue?

Lib specs:

react: 16.0.0-alpha.6
react-native: 0.44.2
react-native-openalpr: 1.0.6

Issue:

Hi there,

I'm sure that I'm missing something fairly obvious but I have tried 4 or 5 times now from scratch to get your library into my project and I consistently get the same error:

I can successfully build and run the project in /Example and I have tried replicating everything I can think of from its setup but nothing so far has worked. I HAVE noticed a few differences that I do not know how to resolve (or if they're significant). On the left you will see the example project (that builds and runs) and on the right you will see the equivalent screen/section in my project where I see differences:

Screen Shots

In the above SS, there is a folder in the Frameworks library called AssetsLibrary that does not appear in the instructions. Also the individual frameworks appear red, very peculiar.

Once again in the Build Phases the references to the frameworks are visually very different and I'm not sure why this is or if it matters.

Guess:

When I import the frameworks from node_modules/react-native-openalpr/ios/Frameworks, nothing gets added to my Framework Search Paths. This strikes me as meaningful, especially with the above-mentioned visual differences I'm seeing.

Any help would be greatly appreciated!

i have a new issue, i want to make a capture screen in the same moment when onPlateRecognizer() return a plate number, a different image beside off the image for recogoneze plate for save this in phone memory ( i need this for android and ios ) please, help me ! :)

After I linked openalpr to my xcode project, but it cannot run successfully:

And my pod file:

Could you please help me on this?

Thanks for the work you've put into this. Looks really promising.

However, I'm struggling to get the Example project working on Android, it crashes as soon as the camera mounts with the following. Can anyone give me any pointers?

There has to be a way to just run react-native link, right? Surely we don't have to manually change all of this in Xcode, right...?

I followed the steps given but not able to run the project , the error being shown is
import com.sandro.openalpr.CameraReactPackage;

but here sandro package does not exists?

Trying to implement the project on IOS, the application builds and launches fine both in the simulator and a real device, but after accepting the access to camera prompt the application hangs on a black screen, the camera never opens. There is no build or runtime errors output in Xcode, the only warning output is;

ALPRCameraManager requires main queue setup since it overrides `constantsToExport` but doesn't implement `requiresMainQueueSetup`. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of

Environment:

MacOS 10.14
Xcode 10
IOS 12

react: 16.6.3
react-native 0.58.4

There's not much else to go on as the build succeeds with no errors. Has anyone experienced a similar issue or have any ideas what might be the cause?

I used the react-native-openalpr to have a good license plate scanner on my app, it was working prefect. But now with iOS 12.4.1 on my iPhone 8 I get random crashing of the app.
Sometimes everything works great and the plate scanner works very good.
But on the other side the app is crashing immediately on camera open.

I debugged the code to the file
react-native-openalpr/ios/PlateScanner.mm on Line 60
Link to code segment

delegate->recognize(colorImage.data, (int)colorImage.elemSize(), colorImage.cols, colorImage.rows, regionsOfInterest);

I get a repeating error EXC_BAD_ACCESS (code=1, address=0x20) on this line.

I already excluded the fields colorImage.elemSize(), colorImage.cols, colorImage.rows, regionsOfInterest on xcode debug.

So I assume it caused by the camera image on field colorImage.data.

Can you give me more insight about possible causes if its related to ios update?

Thank you in advance

when i download and run this code i will get un error like React/RCTBridge.h file not found. how to achieve this issue. Please help me.

What can I do to solve this error on android?

I tried setting up the example given with the project. When I try running "react-native run-android" to build apk, I am seeing the following error

Evaluating project ':opencv' using build file 'C:\mani\AwesomeProject\node_modules\react-native-openaplr\android\libraries\opencv\build.gradle'.

Looks the project stopped compilation once opencv building is reached. Would anyone please help on how to fix this issue.

Hi,

Is all of these files under MIT license? I though that OpenALPR files could be under GPL3?

-t

i think it might related to the the new react-native 64-bit support.
does the libary going to support "arm64-v8a" architecture?

I'm wondering how you managed to openalpr to iOS? The reason I need to compile it by myself is that I'd like to change and debug the openalpr. Thanks.

Running the example on device Nexus 5x, Android 8.1.0

For some reason the image is flipped both horizontally and vertically, so upper left corner in real word is in bottom right corner. Plate numbers are read as camera sees them. Switching orientation only rotates the menu.

Works alright on nexus 4, Android 5.1.1

Can not recognize the plate, is someone going through it?
Device: Moto G4

This is probably a no-brainer, but how do I call the capture function on this.camera ref?

I'm switching from an existing 'react-native-camera' implementation to 'react-native-openalpr' where the "take picture" function for 'react-native-camera' is this.camera.capture(). On the description of 'react-native-openalpr' it says that its camera is based off of 'react-native-camera' so I assume that the naming conventions would be similar.

I'm looking through the console log of this.camera ref but I cannot seem to find the equivalent function of capture. Can someone point this out to me please?

Followed this guide: https://github.com/cardash/react-native-openalpr#running-the-example-project-on-android-while-developing to get the example project running. In step 4 I get the following errors in Android Studio.

Expected Behavior

Android Studio Gradle should build without a problem.

Software versions

• OS platform and version: Microsoft Windows 10 Pro, Version 10.0.16299 Build 16299
• NodeJS version: v6.11.4
• React Native version: 0.41.2

We are in desperate need of new 64 bit libraries. This module is using
https://github.com/SandroMachado/openalpr-android
who got libraties from
https://github.com/sujaybhowmick/openalpr-droidapp-native
who compiled somehow
https://github.com/openalpr/openalpr

Please join me at https://gitter.im/react-native-openalpr/community to discuss how can we compile new 64 bit libraries. Without your help it would be hard.

Hi,

1st, thanks for your job !

I'm facing a problem in my project, even after installing the whole plugin.

I use RN 0.60.4 and RN Camera 2.9.0.

The tag used is

No compile problem but after launch I've got "null is not an object (evaluating CameraManager.Aspect).

Can it be related to using RN Camera in the same project ?

React native version 0.60.4

Fetching podspec for RNOpenAlpr from ../node_modules/react-native-openalpr/ios
[!] The RNOpenAlpr pod failed to validate due to 1 error:
- ERROR | attributes: Missing required attribute homepage.
- WARN | source: The version should be included in the Git tag.

Is it possible to update the this project to work with the latest project:

this is the error i get on a blank react template

I follow the instructions as per the install documentation but I got an errror:

ld: framework not found openalpr
clang: error: linker command failed with exit code 1 (use -v to see invocation)

It looks like after adding the frameworks to the project there were no updates on framework search path. But if I try to manually add the path

$(PROJECT_DIR)/../node_modules/react-native-openalpr/ios/Frameworks

I got the error:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_ALAssetsLibrary", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any idea? I'm on XCode 9.2
