QT编译环境配置 28 | 29 | #### #1.QT Android环境配置 30 | 31 | 该部分我们参考了B站教程：. 32 | 33 | + 下载section 1中的环境 34 | + 安装JDK8 35 | + 解压android-ndk r21 36 | + 解压android-jdk 37 | + 按照如下图配置QT 38 | 39 | ![](./docs/2022-02-04_105740.png) 40 | 41 | 42 | :zap: 为什么选择qt5.14.2和android-ndk r21 ? 43 | 44 | 为了方便和NCNN结合，在使用NCNN时发现 45 | 46 | 1. 用较低版本NDK编译失败，亲测用r15c可以，如果需要vulkan，需要ndk18以上，但是18以上不支持gcc了，默认clang 47 | 2. 较低版本Qt用gcc，高版本用clang，因此高版本应当可以直接用官方公布的最新的编译好的库，用不了的话再自己编译 48 | 49 | 因此我们选择了qt5.14.2和android-ndk r21. 50 | 51 | 52 | #### #2.QT OpenCV Android环境配置 53 | 54 | 我们尝试了opencv-android-sdk的不同版本，发现在qt5.14.2下opencv-4.1.0-android-sdk是可以正常工作的，因此我们最终选择opencv-android-sdk 55 | 56 | + 解压opencv-4.1.0-android-sdk.zip 57 | + 打开QtCreater按照如下步骤配置opencv的编译环境 58 | 59 | ![](./docs/2022-02-04_120855.png) 60 | 61 | ![](./docs/2022-02-04_121504.png) 62 | 63 | 为了方便大家配置，下面提供文本供复制 64 | ``` 65 | android { 66 | ANDROID_OPENCV = D:/QT/OpenCV-android-sdk/sdk/native 67 | #ANDROID_OPENCV = D:/NCNN/opencv-mobile-4.5.1-android/sdk/native 68 | INCLUDEPATH += \ 69 | $$ANDROID_OPENCV/jni/include/opencv2 \ 70 | $$ANDROID_OPENCV/jni/include \ 71 | D:/NCNN/ncnn-20211208-android/armeabi-v7a/include \ 72 | D:/NCNN/ncnn-20211208-android/armeabi-v7a/include/ncnn 73 | 74 | 75 | LIBS += \ 76 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_ml.a \ 77 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_objdetect.a \ 78 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_calib3d.a \ 79 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_video.a \ 80 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_features2d.a \ 81 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_highgui.a \ 82 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_flann.a \ 83 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_imgproc.a \ 84 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_dnn.a \ 85 | $$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_core.a \ 86 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/libcpufeatures.a \ 87 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/libIlmImf.a \ 88 | #$$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/liblibjasper.a \ 89 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/liblibjpeg-turbo.a \ 90 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/liblibpng.a \ 91 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/liblibprotobuf.a \ 92 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/liblibtiff.a \ 93 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/liblibwebp.a \ 94 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/libquirc.a \ 95 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/libtbb.a \ 96 | $$ANDROID_OPENCV/3rdparty/libs/armeabi-v7a/libtegra_hal.a \ 97 | $$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_java4.so \ 98 | D:/NCNN/ncnn-20211208-android/armeabi-v7a/lib/libncnn.a \ 99 | D:/QT/android-ndk-r21/platforms/android-28/arch-arm/usr/lib/libandroid.so \ 100 | D:/QT/android-ndk-r21/toolchains/llvm/prebuilt/windows-x86_64/lib64/clang/9.0.8/lib/linux/arm/libomp.a \ 101 | D:/QT/android-ndk-r21/toolchains/llvm/prebuilt/windows-x86_64/lib64/clang/9.0.8/lib/linux/arm/libomp.so 102 | 103 | # opencv-mobile配置 已废弃 104 | #$$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_core.a \ 105 | #$$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_features2d.a \ 106 | #$$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_highgui.a \ 107 | #$$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_imgproc.a \ 108 | #$$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_photo.a \ 109 | #$$ANDROID_OPENCV/staticlibs/armeabi-v7a/libopencv_video.a \ 110 | 111 | # add other file to assets 112 | 113 | data.files += pic/nanodet.png 114 | data.files += pic/ai.png 115 | data.files += pic/carmera.png 116 | data.files += pic/picture.png 117 | data.files += pic/bus.jpg 118 | data.files += model/nanodet_m.param 119 | data.files += model/nanodet_m.bin 120 | 121 | data.path = /assets/pic 122 | INSTALLS += data 123 | 124 | } 125 | ``` 126 | 127 | 128 | :zap: 为什么没有选择 [opencv-mobile](https://github.com/nihui/opencv-mobile) ? 129 | 130 | 首先要说明一下，为什么在opencv-android-sdk正常编译的情况下考虑使用opencv-mobile,原因有两个其中一个原因是opencv-mobile比opencv-android-sdk要小，且包含了我们常用的一些opencv功能,比如： 131 | 132 | + 提供 android 和 ios 平台最小化编译的 opencv 库 133 | + 提供 opencv 2.4.13.7 和 3.4.13 和 4.5.1 三种版本的预编译包 134 | + 提供官方 opencv 缺少的 ios bitcode 版本的预编译包 135 | + 包含基础的 opencv Mat 和矩阵操作，常用的图像处理功能 136 | + 禁用了 C++ RTTI 和 exceptions 137 | 138 | 第二个原因是最主要的原因，就像上述最后一条提到的，opencv-mobile库禁用了C++ RTTI和exceptions，而opencv-android-sdk是需要开启的，在QT中同时使用opencv和ncnn中关于C++ RTTI和exceptions这两个库是有冲突的，特别在使用自定义的层时（比如YOLOv5和YOLOX中的自定义层）ncnn需要禁用C++ RTTI和exceptions.这里nihui大佬个我们提供了[两个解决方案](https://github.com/Tencent/ncnn/issues/2694)： 139 | ``` 140 | 是否有同时用到 opencv 库？官方的 opencv 库是需要开启 rtti 的，这和目前 ncnn 的预编译包在使用自定义层时会不兼容 141 | 第一种方法是使用 NCNN_DISABLE_RTTI=OFF 自己编译下ncnn库 142 | 第二种方法是编译你的so时 -fno-rtti -fno-exceptions，可以配合 https://github.com/nihui/opencv-mobile 使用,像这样： 143 | #QMAKE_CFLAGS += -fno-rtti 144 | #QMAKE_CXXFLAGS += -fno-rtti 145 | ``` 146 | 147 | 现在说一下为什么我最终没有选择，当我把4.5.1的编译版本用在QT中时，会提示我一些错误，错误类型在该issues:,最终我没有解决，因此放弃了使用opencv-mobile. 148 | 149 | 150 | #### #3.NCNN vs2019编译 151 | 152 | nihui提供了各种编译的版本在ncnn官方repo的release中，我们下载了[ncnn-20211208-full-source.zip](https://github.com/Tencent/ncnn/releases),并在vs2019中重新编译. 153 | 154 | + 编译protobuf 3.4.0 155 | 156 | Protobuf是一种平台无关、语言无关、可扩展且轻便高效的序列化数据结构的协议，可以用于网络通信和数据存储。 157 | 从[该地址](https://github.com/google/protobuf/archive/v3.4.0.zip)下载protobuf3.4.0的压缩包，解压后放在之前新建的文件中，然后在开始菜单找到`Visual Studio 2019=>x64 Native Tools Command Prompt for VS 2019右击，点击更多，以管理员身份运行`，输入以下命令编译protobuf3.4.0： 158 | 159 | 160 | ``` 161 | cd 162 | mkdir build-vs2019 163 | cd build-vs2019 164 | cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%cd%/install -Dprotobuf_BUILD_TESTS=OFF -Dprotobuf_MSVC_STATIC_RUNTIME=OFF ../cmake 165 | nmake 166 | nmake install 167 | 168 | ``` 169 | 其中protobuf-root-dir是你的protobuf解压的路径. 安装完成后的build-vs2019文件夹，之后编译ncnn的时候需要用到. 170 | 171 | + 安装VulkanSDK 1.2.148.0 172 | 173 | 我们这次并没有开启ncnn的Vulkan,但是为了完整的安装，该步骤我们在这里也提供給大家.vulkan是新一代的图形和计算API，它提供了对现代图形处理器的高效、跨平台访问，这些图形处理器应用于各种各样的设备，从pc和主机到移动电话和嵌入式平台。ncnn支持vulkan使用gpu进行加速。当然如果在编译ncnn的时候如果不想使用gpu可跳过此步骤。从下载处下载VulkanSDK 1.2.148.0 的win安装版本。下载完成后一键安装。 174 | 175 | + 编译ncnn框架-ncnn-full-source 176 | 177 | 在ncnn-release中下载ncnn-full-source.zip。 在开始菜单找到`Visual Studio 2019=>x64 Native Tools Command Prompt for VS 2019`右击，点击更多，以管理员身份运行，输入以下命令编译ncnn： 178 | ``` 179 | 180 | cd 181 | mkdir build-vs2019 182 | cd build-vs2019 183 | cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%cd%/install 184 | -DProtobuf_INCLUDE_DIR=/build-vs2019/install/include 185 | -DProtobuf_LIBRARIES=/build-vs2019/install/lib/libprotobuf.lib 186 | -DProtobuf_PROTOC_EXECUTABLE=/build-vs2019/install/bin/protoc.exe 187 | -DNCNN_VULKAN=OFF .. -DOpenCV_DIR=/build 188 | nmake 189 | nmake install 190 | 191 | ``` 192 | 193 | 其中 ``是ncnn-full-source的根目录，``是protobuf的根目录，``是opencv的根目录，如果之前放在一个目录下面的话就很容易管理。如果不想使用vulkan，可以将`-DNCNN_VULKAN=OFF`。 194 | 195 | 如果没有报错，恭喜你ncnn编译成功了！ 196 | 197 | 为了验证我们编译的ncnn时可用的，我们创建了一个YOLOX的测试项目，在VS2019中进行测试,在VS2019中做如下配置： 198 | 199 | ![](./docs/vs2019.png) 200 | 201 | 可以正常识别： 202 | ![](./docs/2022-02-04_144250.png) 203 | 204 | 205 | 206 | #### #4.NCNN Android编译 207 | 208 | 209 | + 我们已经安装了android-ndk-r21 210 | + 在开始菜单找到`Visual Studio 2019=>x64 Native Tools Command Prompt for VS 2019`右击，点击更多，以管理员身份运行 211 | + `export ANDROID_NDK=` 212 | + build ncnn android 213 | 214 | ``` 215 | cd 216 | mkdir -p build-android-armv7 217 | cd build-android-armv7 218 | 219 | cmake -DCMAKE_TOOLCHAIN_FILE="$ANDROID_NDK/build/cmake/android.toolchain.cmake" \ 220 | -DANDROID_ABI="armeabi-v7a" -DANDROID_ARM_NEON=ON NCNN_DISABLE_RTTI=OFF\ 221 | -DANDROID_PLATFORM=android-28 .. 222 | 223 | # If you want to enable Vulkan, platform api version >= android-24 is needed 224 | cmake -DCMAKE_TOOLCHAIN_FILE="$ANDROID_NDK/build/cmake/android.toolchain.cmake" \ 225 | -DANDROID_ABI="armeabi-v7a" -DANDROID_ARM_NEON=ON \ 226 | -DANDROID_PLATFORM=android-24 -DNCNN_VULKAN=ON .. 227 | 228 | make -j$(nproc) 229 | make install 230 | ``` 231 | 232 | :zap: 为什么要选择重新编译ncnn ? 233 | 234 | + 官方编译的有些参数是没有打开的，有些参数是我们项目暂时不需要需要编译过程中关闭的 235 | + 编译安卓版本需要关闭C++ RTTI 236 | 237 | 238 | 最后我们将编译好的安卓NCNN库链接到QT 239 | 240 | ![](docs/2022-02-04_150548.png) 241 | ![](docs/2022-02-04_150705.png) 242 | 243 | :zap: 为什么要链接：`libandroid.so`和`libomp.so`?
