Have you ever seen a deep learning based ANPR/ALPR (Automatic Number/License Plate Recognition) engine running at 64fps on a $99 ARM device (Khadas VIM3, 720p video resolution)?

UltimateALPR is the fastest ANPR/ALPR implementation you'll find on the market. Being fast is important but being accurate is crucial.

We use state of the art deep learning techniques to offer unmatched accuracy and precision. As a comparison this is #33 times faster than OpenALPR on Android. (see benchmark section for more information).

No need for special or dedicated GPUs, everything is running on CPU with SIMD ARM NEON optimizations, fixed-point math operations and multithreading. This opens the doors for the possibilities of running fully featured ITS (Intelligent Transportation System) solutions on a camera without soliciting a cloud. Being able to run all ITS applications on the device will significantly lower the cost to acquire, deploy and maintain such systems. Please check Device-based versus Cloud-based solution section for more information about how this would reduce the cost.

The next video shows the Recognizer sample running on Windows:

---

The code is accelerated on CPU, GPU, VPU and FPGA, thanks to CUDA, NVIDIA TensorRT and Intel OpenVINO.

In addition to License Plate Recognition (LPR) we support Image Enhancement for Night-Vision (IENV), License Plate Country Identification (LPCI), Vehicle Color Recognition (VCR), Vehicle Make Model Recognition (VMMR), Vehicle Body Style Recognition (VBSR), Vehicle Direction Tracking (VDT) and Vehicle Speed Estimation (VSE).

On high-end NVIDIA GPUs like the Tesla V100 the frame rate is 315 fps which means 3.17 millisecond inference time. On high-end CPUs like Intel Xeon the maximum frame rate could be up to 237fps, thanks to OpenVINO. On low-end CPUs like the Raspberry Pi 4 the average frame rate is 12fps.

Don't take our word for it, come check our implementation. No registration, license key or internet connection is required, just clone the code and start coding/testing. Everything runs on the device, no data is leaving your computer. The code released here comes with many ready-to-use samples for Android, Raspberry Pi, Linux and Windows to help you get started easily.

You can also check our online cloud-based implementation (no registration required) to check out the accuracy and precision before starting to play with the SDK.

Please check full documentation at https://www.doubango.org/SDKs/anpr/docs/

Getting started

The SDK works on many platforms and comes with support for many programming languages but the next sections focus on Android, Raspberry Pi, Linux and Windows.

Android

The next sections are about Android and Java API.

Sample applications (Android)

The source code comes with #4 Android sample applications: Benchmark, VideoParallel, VideoSequential and ImageSnap.

Benchmark (Android)

This application is used to check everything is ok and running as fast as expected. The information about the maximum frame rate (237fps on Intel Xeon, 64fps on Khadas VIM3 and 12fps on Raspberry Pi 4) could be checked using this application. It's open source and doesn't require registration or license key.

VideoParallel (Android)

This application should be used as reference code by any developer trying to add ultimateALPR to their products. It shows how to detect and recognize license plates in realtime using live video stream from the camera. Please check Parallel versus sequential processing section for more info about parellel mode.

VideoSequential (Android)

Same as VideoParallel but working on sequential mode which means slower. This application is provided to ease comparing the modes: Parallel versus Sequential.

ImageSnap (Android)

This application reads and display the live video stream from the camera but only recognize an image from the stream on demand.

Trying the samples (Android)

To try the sample applications on Android:

1. Open Android Studio and select "Open an existing Android Studio project"

2. Navigate to ultimateALPR-SDK/samples, select android folder and click OK

3. Select the sample you want to try (e.g. videoparallel) and press run. Make sure to have the device on landscape mode for better experience.

Adding the SDK to your project (Android)

The SDK is distributed as an Android Studio module and you can add it as reference or you can also build it and add the AAR to your project. But, the easiest way to add the SDK to your project is by directly including the source.

In your build.gradle file add:

android {

      # This is the block to add within "android { } " section
      sourceSets {
         main {
             jniLibs.srcDirs += ['path-to-your-ultimateALPR-SDK/binaries/android/jniLibs']
             java.srcDirs += ['path-to-your-ultimateALPR-SDK/java/android']
             assets.srcDirs += ['path-to-your-ultimateALPR-SDK/assets/models']
         }
      }
}

Using the Java API (Android)

It's hard to be lost when you try to use the API as there are only 3 useful functions: init, process and deInit.

The C++ API is defined here.

error while loading shared libraries: libultimate_alpr-sdk.so: cannot open shared object file: No such file or directory

Hi. I'm trying to use the recognizer sample on a Raspberry Pi 4

After building on the Pi itself with:

cd ultimateALPR-SDK-master/samples/c++/recognizer
g++ recognizer.cxx -O3 -I../../../c++ -L../../../binaries/raspbian/armv7l -lultimate_alpr-sdk -o recognizer

Then when I run the recognizer file, I get this:

 ./recognizer: error while loading shared libraries: libultimate_alpr-sdk.so: cannot open shared object file: No such file or directory

I can find libultimate_alpr-sdk.so in the repo:

pi@raspberrypi:~/ultimateALPR-SDK-master $ find . -name "libultimate_alpr-sdk.so"
./binaries/raspbian/armv7l/libultimate_alpr-sdk.so

How I can resolve this ? Thanks.

I also tried to build with -v to get some more log. Hope this could help:

pi@raspberrypi:~/ultimateALPR-SDK-master/samples/c++/recognizer $ g++ recognizer.cxx -O3 -I../../../c++ -L../../../binaries/raspbian/armv7l -lultimate_alpr-sdk -o recognizer -v

Running the SDK in Python

Hello and thanks for your work,

In the documentation it says that it can be used in Python but I didn't find any example or documentation regarding how to use it with Python. Can you please point me in the right direction?

Thanks

Add support for BGRA32

BGRA32 is on of reference formats for iOS cameras

Add support for network reduction using morph-net

https://github.com/google-research/morph-net

Documentation has instructions to build on Windows, but the Windows binary is nowhere to be found

The documentation in many points give instructions to build on Windows, like here, but it's not possible to build for Windows as the binaries of the library are not available.

Could Doubango add the binaries for Windows? It's impossible to test the application on high end graphics cards at this point in time.

Add support for Korean license plates

Add support for License-Plate-Country-Identification (LPCI)

Referenced binaries are not available

You mention prebuilt binaries in the PDF document which are not available in the repository. Would you mind sharing Windows binaries? (either privately or public)

Add support for BGR24 format (required for VCR)

C# image decoder outputs BGR24 instead of RGB24. Change C# sample to use BGR24 instead of RGB24

Reduce the SDK size to fit into microcontrollers' memory and prepare for Raspberry Pi

Add support for iOS

Multi-threading disabled for ARM32

Inference (detect) hangs when multi-threading is enabled on ARM32 devices. At least on Android devices

Enable auto focus

run the recognizer on linux

Is there any option to run the recognizer on Linux?
I see the examples on Raspbian OS but I need it on ubuntu.
As far as I saw, there is a file called "libultimate_alpr-sdk.so", Is it possible to run this file on Ubuntu?
Thank you.

Sample applications fail to decode grayscale images

This is not an issue in the SDK but the fact that we ignore grayscale format in the code used in C++ samples

Run using python

How do we use this SDK in python. Just need a hint that's all. Thanks!

RuntimeKey changes on Android when the system is upgraded

The RuntimeKey must not change even if the system is upgraded unless a physical component is changed.

Add support for "assets_folder" in JSON configuration entries

The JSON configuration entry will allow setting the path to the assets folder. The folder containing the configuration files and deep learning models

Add support for Y format (Grayscale)

Release Linux and Windows binaries

Can not find the lib sdk at Windows

Hi,
I want to try out your solution but I can not find a library for windows. At CMake I get the folllowing Error:

CMake Error at samples/c++/benchmark/CMakeLists.txt:6 (add_subdirectory):
add_subdirectory given source
"C:/projects/ultimateALPR-SDK/samples/c++/benchmark/../../../../SDK_dev/lib"
which is not an existing directory.

CMake Error at samples/c++/recognizer/CMakeLists.txt:6 (add_subdirectory):
add_subdirectory given source
"C:/projects/ultimateALPR-SDK/samples/c++/recognizer/../../../../SDK_dev/lib"
which is not an existing directory.

Also you reference at the c++ sample project to the missing folders:

Can you add the folder and library at "SDK_dev/lib" to your git repo, please?

java.lang.UnsatisfiedLinkError: dlopen failed: /data/app/org.doubango.ultimateAlpr-2/lib/x86/libultimateALPR_SDK.so: has text relocations

Hi @DoubangoTelecom , i'm trying to run the code on a NEXUS 9 API 24 Android emulator but i get this "text relocations" error

java.lang.UnsatisfiedLinkError: dlopen failed: /data/app/org.doubango.ultimateAlpr-2/lib/x86/libultimateALPR_SDK.so: has text relocations

Can you provide an updated version of "libultimateALPR_SDK.so" without this error, or tell me if the source codes are available so i can do it myself (compile the code with latest NDK) ?

Thanks!

Is this problem expected on a emulator (it will only work on real RPis) or am i doing something wrong here?

Thanks

Can't recognise the last character in android.

When i launched your sdk and activity in android it works fine .. but everytime it fails to recognise the last character it shows * in the last character. Any suggestions???

Last character is always a Asterisk

Hi. It is some error or it´s a Mask that you put in the code ?
I am trying to use your example, but the last plate character is always an "*"
