OpenCV进行Android的 - 不是OpenCV的，Android的SDK [英] openCV for Android - NOT opencv-android-sdk
问题描述
我想在我的Android应用程序中使用某些本地C ++ code /库。 C ++的一部分，在很大程度上基于OpenCV。
I want to use some native c++ code/library in my Android application. The c++ part is heavily based on openCV.
我知道的OpenCV-Android的SDK，并已看到很多详尽的教程就如何与Android工作室做到这一点（如<一个href=\"http://hujiaweibujidao.github.io/blog/2014/10/22/android-ndk-and-opencv-development-with-android-studio/\"相对=nofollow>这个），但这些都只是用OpenCV的，Android的SDK只支持的OpenCV函数的有限子集（我不是在谈论那些不使移动设备上的感像GPU相关的功能，但根本就没有在OpenCV的，Android的SDK存在和其他一些功能，我需要他们的C ++ code）。
I am aware of opencv-android-sdk and have seen plenty of detailed tutorials on how to do it with Android Studio (like this one), but these all just use the opencv-android-sdk that only supports a limited subset of openCV functions (I am not talking about those that do not make sense on a mobile device, like gpu-related functionalities, but some other functions that simply do not exist in the opencv-android-sdk and I need them for the c++ code).
不管怎样，我的问题是：我可以采用某种编译和使用（使用NDK等）中的全部模块的在我的Android Studio项目的OpenCV
Anyway, my question is: can I somehow compile and use the "full set of modules" of openCV in my Android Studio project (using NDK, etc.)?
我看了也这个，并声称 [它]将打造最OpenCV的模块[Android游戏]，但它不是我清楚如何使用它...
I saw also this one, and it claims that "[it] will build most of the OpenCV modules [for android]", but it is not clear to me how to use it...
任何暗示将是非常美联社preciated！
Any hint would be highly appreciated!
推荐答案
OK！我想我想通了！
基本上是需要遵循<一个href=\"http://hujiaweibujidao.github.io/blog/2014/10/22/android-ndk-and-opencv-development-with-android-studio/\"相对=nofollow>本教程，只是替换Android.mk路径指向编译后的完整版本，而不是OpenCV的，Android的SDK（以及一些其他小的变化的OpenCV;对于那些我只是在这里我有什么复制 Android.mk 和 Application.mk ）。
OK! I guess I figured it out!
Basically one needs to follow this tutorial, but just replace the path in Android.mk to point to the compiled full version of openCV, instead of openCV-Android-SDK (as well as some other small changes; for those I just copy here what I have in Android.mk and Application.mk).
最后，我的 Android.mk 看起来像这样（ OPENCVROOT 需要正确设置）：
Eventually, my Android.mk looks like this (OPENCVROOT need to be set properly):
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCVROOT:= /path/to/opencv-2.4.10/platforms/build_android_arm
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/OpenCV.mk
LOCAL_SRC_FILES := main.cpp
LOCAL_LDLIBS += -llog
LOCAL_MODULE := hello
include $(BUILD_SHARED_LIBRARY)
和 Application.mk 是这样的：
APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi-v7a
APP_PLATFORM := android-19
刚上了Android NDK编译OpenCV的一个简短的说明：
Just a short note on compiling openCV with Android NDK:
有关编译使用NDK全OpenCV的，人们仍然可以使用方法中提到 ;该描述是基于NDK-R8E，但如果需要的话，可以下载NDK-r10d并用它来代替。我不得不关闭CUDA相关的部分在OpenCV的源代码，以便与NDK（只需添加 -D WITH_CUDA = OFF 成功编译它 OpenCV的-2.4.10 /平台/脚本/ cmake_android_arm.sh ，在最后一行，后 cmake的，没有工作！）。如果你需要有非自由的模块（如海浪和过筛，不要从GitHub克隆它，只需下载它从的此处;我的方式使用的版本2.4.10）
For compiling full openCV using NDK, one can still use the method mentioned here; the description is based on NDK-r8e, but if needed, one can download NDK-r10d and use it instead. I had to turn-off cuda-related parts in openCV source, in order to successfully compile it with NDK (just adding -D WITH_CUDA=OFF to opencv-2.4.10/platforms/scripts/cmake_android_arm.sh , in the last line, after cmake, does the job!). In case you need to have the nonfree modules (like SURF and SIFT, do NOT clone it from github, just download it in a single zip from here; I used version 2.4.10 by the way).
现在我有机会获得几乎所有的OpenCV函数在本地C ++ code，我融入我的Android应用程序！
Now I have access to almost all openCV functions in the native c++ code that I am integrating into my Android App!
我希望这可以帮助别人呢！
I hope this helps others, too!
