OpenCV for Android

Configure the OpenCV Android environment

1. Download the SDK

The SDK directory structure is as follows:

OpenCV-android-sdk |_samples |_sdk | |_etc | |_java | |_libcxx_helper | |_native | |_3rdparty | |_jni | |_libs | |_arm64_v8a | |_armeabi_v7a | |_x86 | |_x86_64 | |_staticlibs | |_arm64_v8a | |_armeabi_v7a | |_x86 | |_x86_64 |_LICENSE  |_README.androidCopy the code

2. Import OpenCV for Android SDK

   1. Create a new project in Android Studio

   File → New → import Module

   

   2. Select the SDK folder under the previously downloaded package and click OK

   

   3. The Gradle configuration of the opencV SDK is compatible with the Gradle configuration of our new app. That is, the compiled version of the Gradle SDK in the SDK, the minimum version, and the target version are consistent with the app

   app Gradle:

   

   SDK Gradle:

   

   4. Add Opencv for Android dependency

   File → Project Structure → Dependencies → app → + → Module Dependency → SDK

   5. Initialize the OpenCV

   But that’s not all. Now you can actually use the OpenCV library functions directly. OpenCV libraries need to be initialized before they can be used. This can be done with the following code:

   private void OpenCVInit(a) {
       boolean success = OpenCVLoader.initDebug();
       if (success) {
           Log.d(TAG, "OpenCV Lode success");
       } else {
           Log.d(TAG, "OpenCV Lode failed "); }}Copy the code

   Just call OpenCVInit() in onCreate()
