![]() ![]() For this tutorial we have unpacked OpenCV SDK to the C:\Work\OpenCV4Android\ directory.īetter to use a path without spaces in it. Currently it’s OpenCV-2.4.9-android-sdk.zip.Ĭreate a new folder for Android with OpenCV development. Go to the OpenCV download page on SourceForge and download the latest available version. All packages with OpenCV are published on Google Play įor additional information on OpenCV Manager see the: Hardware specific optimizations are automatically enabled on all supported platforms.Compact apk-size, since all applications use the same binaries from Manager and do not store native libs within themselves.OpenCV Manager is an Android service based solution providing the following benefits for OpenCV applications developers: Starting from version 2.4.3 OpenCV4Android SDK uses OpenCV Manager API for library initialization. Todo I’m not sure that this is the best place to talk about OpenCV Manager Generally, it’s more up-to-date, but can refer to not-yet-released functionality. The most recent docs (nightly build) are at. Import them into Eclipse workspace (like described below) and browse the code to learn possible ways of OpenCV use on Android.ĭoc folder contains various OpenCV documentation in PDF format. Samples folder contains sample applications projects and their prebuilt packages (APK). Installation from Internet is the preferable way since OpenCV team may publish updated versions of this packages on the Market. Install the Manager.apk and optional binary_pack.apk if it needed. But devkits without Market or Internet connection require this packages to be installed manually. 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. Sdk/etc folder contains Haar and LBP cascades distributed with OpenCV.Īpk 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). 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/java folder contains an Android library Eclipse project providing OpenCV Java API that can be imported into developer’s workspace Sdk folder contains OpenCV API and libraries for Android: apk | | _ doc | _ samples | _ sdk | | _ etc | | _ java | | _ native | | _ 3 rdparty | | _ jni | | _ libs | | _ armeabi | | _ armeabi - v7a | | _ x86 | | _ LICENSE | _ README. OpenCV - 2.4.9 - android - sdk | _ apk | | _ OpenCV_2. The structure of package contents looks as follows: OpenCV4Android SDK package enables development of Android applications with use of OpenCV library. More details regarding TADP can be found in the Introduction into Android Development guide. You may have used Tegra Android Development Pack ( TADP) released by NVIDIA for Android development environment setup.īeside Android development tools the TADP 2.0 includes OpenCV4Android SDK, so it can be already installed in your system and you can skip to samples section of this tutorial.
