|
||||||
| Compatibility | OpenCV >= 3.3 | |
|
||||||
|
|
||||||
## Introduction |
|
||||||
In this tutorial you'll know how to run deep learning networks on Android device |
|
||||||
using OpenCV deep learning module. |
|
||||||
|
|
||||||
Tutorial was written for the following versions of corresponding software: |
|
||||||
- Android Studio 2.3.3 |
|
||||||
- OpenCV 3.3.0+ |
|
||||||
|
|
||||||
## Requirements |
|
||||||
|
|
||||||
- Download and install Android Studio from https://developer.android.com/studio. |
|
||||||
|
|
||||||
- Get the latest pre-built OpenCV for Android release from https://github.com/opencv/opencv/releases and unpack it (for example, `opencv-5.X.Y-android-sdk.zip`). |
|
||||||
|
|
||||||
- Download MobileNet object detection model from https://github.com/chuanqi305/MobileNet-SSD. We need a configuration file `MobileNetSSD_deploy.prototxt` and weights `MobileNetSSD_deploy.caffemodel`. |
|
||||||
|
|
||||||
## Create an empty Android Studio project |
|
||||||
- Open Android Studio. Start a new project. Let's call it `opencv_mobilenet`. |
|
||||||
 |
|
||||||
|
|
||||||
- Keep default target settings. |
|
||||||
 |
|
||||||
|
|
||||||
- Use "Empty Activity" template. Name activity as `MainActivity` with a |
|
||||||
corresponding layout `activity_main`. |
|
||||||
 |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
- Wait until a project was created. Go to `Run->Edit Configurations`. |
|
||||||
Choose `USB Device` as target device for runs. |
|
||||||
 |
|
||||||
Plug in your device and run the project. It should be installed and launched |
|
||||||
successfully before we'll go next. |
|
||||||
@note Read @ref tutorial_android_dev_intro in case of problems. |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
## Add OpenCV dependency |
|
||||||
|
|
||||||
- Go to `File->New->Import module` and provide a path to `unpacked_OpenCV_package/sdk/java`. The name of module detects automatically. |
|
||||||
Disable all features that Android Studio will suggest you on the next window. |
|
||||||
 |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
- Open two files: |
|
||||||
|
|
||||||
1. `AndroidStudioProjects/opencv_mobilenet/app/build.gradle` |
|
||||||
|
|
||||||
2. `AndroidStudioProjects/opencv_mobilenet/openCVLibrary330/build.gradle` |
|
||||||
|
|
||||||
Copy both `compileSdkVersion` and `buildToolsVersion` from the first file to |
|
||||||
the second one. |
|
||||||
|
|
||||||
`compileSdkVersion 14` -> `compileSdkVersion 26` |
|
||||||
|
|
||||||
`buildToolsVersion "25.0.0"` -> `buildToolsVersion "26.0.1"` |
|
||||||
|
|
||||||
- Make the project. There is no errors should be at this point. |
|
||||||
|
|
||||||
- Go to `File->Project Structure`. Add OpenCV module dependency. |
|
||||||
 |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
- Install once an appropriate OpenCV manager from `unpacked_OpenCV_package/apk` |
|
||||||
to target device. |
|
||||||
@code |
|
||||||
adb install OpenCV_3.3.0_Manager_3.30_armeabi-v7a.apk |
|
||||||
@endcode |
|
||||||
|
|
||||||
- Congratulations! We're ready now to make a sample using OpenCV. |
|
||||||
|
|
||||||
## Make a sample |
|
||||||
Our sample will takes pictures from a camera, forwards it into a deep network and |
|
||||||
receives a set of rectangles, class identifiers and confidence values in `[0, 1]` |
|
||||||
range. |
|
||||||
|
|
||||||
- First of all, we need to add a necessary widget which displays processed |
|
||||||
frames. Modify `app/src/main/res/layout/activity_main.xml`: |
|
||||||
@include android/mobilenet-objdetect/res/layout/activity_main.xml |
|
||||||
|
|
||||||
- Put downloaded `MobileNetSSD_deploy.prototxt` and `MobileNetSSD_deploy.caffemodel` |
|
||||||
into `app/build/intermediates/assets/debug` folder. |
|
||||||
|
|
||||||
- Modify `/app/src/main/AndroidManifest.xml` to enable full-screen mode, set up |
|
||||||
a correct screen orientation and allow to use a camera. |
|
||||||
@include android/mobilenet-objdetect/gradle/AndroidManifest.xml |
|
||||||
|
|
||||||
- Replace content of `app/src/main/java/org/opencv/samples/opencv_mobilenet/MainActivity.java`: |
|
||||||
@include android/mobilenet-objdetect/src/org/opencv/samples/opencv_mobilenet/MainActivity.java |
|
||||||
|
|
||||||
- Launch an application and make a fun! |

General info |
|
||||||
------------ |
|
||||||
|
|
||||||
OpenCV4Android SDK package enables development of Android applications with use of OpenCV library. |
|
||||||
|
|
||||||
The structure of package contents looks as follows: |
|
||||||
|
|
||||||
OpenCV-2.4.9-android-sdk |
|
||||||
|_ apk |
|
||||||
| |_ OpenCV_2.4.9_binary_pack_armv7a.apk |
|
||||||
| |_ OpenCV_2.4.9_Manager_2.18_XXX.apk |
|
||||||
| |
|
||||||
|_ doc |
|
||||||
|_ samples |
|
||||||
|_ sdk |
|
||||||
| |_ etc |
|
||||||
| |_ java |
|
||||||
| |_ native |
|
||||||
| |_ 3rdparty |
|
||||||
| |_ jni |
|
||||||
| |_ libs |
|
||||||
| |_ armeabi |
|
||||||
| |_ armeabi-v7a |
|
||||||
| |_ x86 |
|
||||||
| |
|
||||||
|_ LICENSE |
|
||||||
|_ README.android |
|
||||||
|
|
||||||
- `sdk` folder contains OpenCV API and libraries for Android: |
|
||||||
- `sdk/java` folder contains an Android library Eclipse project providing OpenCV Java API that can |
|
||||||
be imported into developer's workspace; |
|
||||||
- `sdk/native` folder contains OpenCV C++ headers (for JNI code) and native Android libraries |
|
||||||
(\*.so and \*.a) for ARM-v5, ARM-v7a and x86 architectures; |
|
||||||
- `sdk/etc` folder contains Haar and LBP cascades distributed with OpenCV. |
|
||||||
- `apk` folder contains Android packages that should be installed on the target Android device to |
|
||||||
enable OpenCV library access via OpenCV Manager API (see details below). |
|
||||||
|
|
||||||
On production devices that have access to Google Play Market (and Internet) these packages will |
|
||||||
be installed from Market on the first start of an application using OpenCV Manager API. But |
|
||||||
devkits without Market or Internet connection require this packages to be installed manually. |
|
||||||
Install the Manager.apk and optional binary_pack.apk if it needed. See `Manager Selection` |
|
||||||
for details. |
|
||||||
|
|
||||||
@note Installation from Internet is the preferable way since OpenCV team may publish updated |
|
||||||
versions of this packages on the Market. |
|
||||||
|
|
||||||
- `samples` folder contains sample applications projects |
|
||||||
and their prebuilt packages (APK). Import them into Eclipse workspace (like described below) and |
|
||||||
browse the code to learn possible ways of OpenCV use on Android. |
|
||||||
|
|
||||||
- `doc` folder contains various OpenCV documentation in PDF format. It's also available online at |
|
||||||
<http://docs.opencv.org>. |
|
||||||
@note The most recent docs (nightly build) are at <http://docs.opencv.org/5.x>. Generally, it's more |
|
||||||
up-to-date, but can refer to not-yet-released functionality. |
|
||||||
@todo I'm not sure that this is the best place to talk about OpenCV Manager |
|
||||||
|
|
||||||
Starting from version 2.4.3 OpenCV4Android SDK uses OpenCV Manager API for library initialization. |
|
||||||
OpenCV Manager is an Android service based solution providing the following benefits for OpenCV |
|
||||||
applications developers: |
|
||||||
|
|
||||||
- Compact apk-size, since all applications use the same binaries from Manager and do not store |
|
||||||
native libs within themselves; |
|
||||||
- Hardware specific optimizations are automatically enabled on all supported platforms; |
|
||||||
- Automatic updates and bug fixes; |
|
||||||
- Trusted OpenCV library source. All packages with OpenCV are published on Google Play; |
|
||||||
|
|
||||||
|
|
||||||
Manual OpenCV4Android SDK setup |
|
||||||
------------------------------- |
|
||||||
|
|
||||||
### Get the OpenCV4Android SDK |
|
||||||
|
|
||||||
-# Go to the [OpenCV download page on |
|
||||||
SourceForge](http://sourceforge.net/projects/opencvlibrary/files/) and download |
|
||||||
the latest available version. This tutorial is based on this package: [OpenCV-2.4.9-android-sdk.zip](http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.4.9/OpenCV-2.4.9-android-sdk.zip/download). |
|
||||||
-# Create a new folder for Android with OpenCV development. For this tutorial we have unpacked |
|
||||||
OpenCV SDK to the `C:\Work\OpenCV4Android\` directory. |
|
||||||
|
|
||||||
@note Better to use a path without spaces in it. Otherwise you may have problems with ndk-build. |
|
||||||
|
|
||||||
-# Unpack the SDK archive into the chosen directory. |
|
||||||
|
|
||||||
You can unpack it using any popular archiver (e.g with 7-Zip): |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
On Unix you can use the following command: |
|
||||||
@code{.bash} |
|
||||||
unzip ~/Downloads/OpenCV-2.4.9-android-sdk.zip |
|
||||||
@endcode |
|
||||||
|
|
||||||
### Import OpenCV library and samples to the Eclipse |
|
||||||
|
|
||||||
-# Start Eclipse and choose your workspace location. |
|
||||||
|
|
||||||
We recommend to start working with OpenCV for Android from a new clean workspace. A new Eclipse |
|
||||||
workspace can for example be created in the folder where you have unpacked OpenCV4Android SDK |
|
||||||
package: |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
-# Import OpenCV library and samples into workspace. |
|
||||||
|
|
||||||
OpenCV library is packed as a ready-for-use [Android Library |
|
||||||
Project](http://developer.android.com/guide/developing/projects/index.html#LibraryProjects). You |
|
||||||
can simply reference it in your projects. |
|
||||||
|
|
||||||
Each sample included into the `OpenCV-2.4.9-android-sdk.zip` is a regular Android project that |
|
||||||
already references OpenCV library. Follow the steps below to import OpenCV and samples into the |
|
||||||
workspace: |
|
||||||
|
|
||||||
- Right click on the Package Explorer window and choose Import... option from the context |
|
||||||
menu: |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
- In the main panel select General --\> Existing Projects into Workspace and press Next |
|
||||||
button: |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
- In the Select root directory field locate your OpenCV package folder. Eclipse should |
|
||||||
automatically locate OpenCV library and samples: |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
- Click Finish button to complete the import operation. |
|
||||||
|
|
||||||
@note OpenCV samples are indeed **dependent** on OpenCV library project so don't forget to import it to your workspace as well. |
|
||||||
|
|
||||||
After clicking Finish button Eclipse will load all selected projects into workspace, and you |
|
||||||
have to wait some time while it is building OpenCV samples. Just give a minute to Eclipse to |
|
||||||
complete initialization. |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
Once Eclipse completes build you will have the clean workspace without any build errors: |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
@anchor tutorial_O4A_SDK_samples |
|
||||||
### Running OpenCV Samples |
|
||||||
|
|
||||||
At this point you should be able to build and run the samples. Keep in mind, that face-detection and |
|
||||||
Tutorial 2 - Mixed Processing include some native code and require Android NDK and NDK/CDT plugin |
|
||||||
for Eclipse to build working applications. If you haven't installed these tools, see the |
|
||||||
corresponding section of @ref tutorial_android_dev_intro. |
|
||||||
|
|
||||||
**warning** |
|
||||||
|
|
||||||
Please consider that some samples use Android Java Camera API, which is accessible with an AVD. |
|
||||||
|
|
||||||
@note Recent *Android SDK tools, revision 19+* can run ARM v7a OS images but they available not for |
|
||||||
all Android versions. |
|
||||||
|
|
||||||
Well, running samples from Eclipse is very simple: |
|
||||||
|
|
||||||
- Connect your device with adb tool from Android SDK or create an emulator with camera support. |
|
||||||
- See [Managing Virtual Devices](http://developer.android.com/guide/developing/devices/index.html) document for help |
|
||||||
with Android Emulator. |
|
||||||
- See [Using Hardware Devices](http://developer.android.com/guide/developing/device.html) for |
|
||||||
help with real devices (not emulators). |
|
||||||
|
|
||||||
- Select project you want to start in Package Explorer and just press Ctrl + F11 or select option |
|
||||||
Run --\> Run from the main menu, or click Run button on the toolbar. |
|
||||||
|
|
||||||
@note Android Emulator can take several minutes to start. So, please, be patient. \* On the first |
|
||||||
run Eclipse will ask you about the running mode for your application: |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
- Select the Android Application option and click OK button. Eclipse will install and run the |
|
||||||
sample. |
|
||||||
|
|
||||||
Chances are that on the first launch you will not have the [OpenCV |
|
||||||
Manager](https://docs.google.com/a/itseez.com/presentation/d/1EO_1kijgBg_BsjNp2ymk-aarg-0K279_1VZRcPplSuk/present#slide=id.p) |
|
||||||
package installed. In this case you will see the following message: |
|
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
To get rid of the message you will need to install OpenCV Manager and the appropriate |
|
||||||
OpenCV binary pack. Simply tap Yes if you have *Google Play Market* installed on your |
|
||||||
device/emulator. It will redirect you to the corresponding page on *Google Play Market*. |
|
||||||
|
|
||||||
If you have no access to the *Market*, which is often the case with emulators - you will need to |
|
||||||
install the packages from OpenCV4Android SDK folder manually. See `Manager Selection` for |
|
||||||
details. |
|
||||||
@code{.sh} |
|
||||||
<Android SDK path>/platform-tools/adb install <OpenCV4Android SDK path>/apk/OpenCV_2.4.9_Manager_2.18_armv7a-neon.apk |
|
||||||
@endcode |
|
||||||
|
|
||||||
@note armeabi, armv7a-neon, arm7a-neon-android8, mips and x86 stand for platform targets: |
|
||||||
- armeabi is for ARM v5 and ARM v6 architectures with Android API 8+, |
|
||||||
- armv7a-neon is for NEON-optimized ARM v7 with Android API 9+, |
|
||||||
- arm7a-neon-android8 is for NEON-optimized ARM v7 with Android API 8, |
|
||||||
- mips is for MIPS architecture with Android API 9+, |
|
||||||
- x86 is for Intel x86 CPUs with Android API 9+. |
|
||||||
|
|
||||||
@note |
|
||||||
If using hardware device for testing/debugging, run the following command to learn its CPU |
|
||||||
architecture: |
|
||||||
@code{.sh} |
|
||||||
adb shell getprop ro.product.cpu.abi |
|
||||||
@endcode |
|
||||||
If you're using an AVD emulator, go Window \> AVD Manager to see the list of available devices. |
|
||||||
Click Edit in the context menu of the selected device. In the window, which then pop-ups, find |
|
||||||
the CPU field. |
|
||||||
|
|
||||||
@note |
|
||||||
You may also see section `Manager Selection` for details. |
|
||||||
|
|
||||||
When done, you will be able to run OpenCV samples on your device/emulator seamlessly. |
|
||||||
|
|
||||||
- Here is Sample - image-manipulations sample, running on top of stock camera-preview of the |
|
||||||
emulator. |
