opencv---之如何安装opencv和opencv_contrib

概览

在 Ubuntu 类系统上安装 OpenCV 可以直接使用 apt 进行安装，直接在终端键入以下命令即可：

$ sudo apt install libopencv-dev

    1

如果只是使用 OpenCV 的基本功能，那么上面的安装方法非常简单快捷。但是如果要使用一些额外的算法，比如人脸识别，那就需要安装 opencv_contrib 来实现。本文记录了从源码安装 OpenCV 以及 opencv_contrib 的方法。

从源码安装 OpenCV 的基本流程如下：

    安装相关的依赖项
    下载 OpenCV 源码以及 opencv_contirb 源码
    配置编译环境
    编译安装

系统环境

ARMBIAN 5.38 stable Ubuntu 16.04.3 LTS 3.4.113-sun8i, Ubuntu 类系统都可以按照该方法进行安装。
安装步骤
1. 安装依赖项以及编译环境

sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

 

2. 下载 OpenCV 以及 opencv_conrib 源码

wget -O opencv-3.3.0.zip https://github.com/Itseez/opencv/archive/3.3.0.zip
wget -O opencv_contrib.zip https://github.com/Itseez/opencv_contrib/archive/3.2.0.zip
unzip opencv-3.3.0.zip
unzip opencv_contrib.zip
cd opencv-3.3.0

 

3. 编译及安装

mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_C_EXAMPLES=OFF \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D OPENCV_EXTRA_MODULES_PATH= \
    -D BUILD_EXAMPLES=ON \
    -D ENABLE_NEON=ON ..

 

运行以下命令进行编译：

make -j4

    1

编译的时间和具体的硬件环境有很大的关系，在 Orange Pi 这样的嵌入式设备上需要一个小时以上，在 PC 上编译速度较快。
编译完成后执行

sudo make install

 

注：cmake报错

ffmeg/.... .h not found

或者什么什么包没有找到，重新建立一个干净的build再cmake一次

还有个错误 就是ubuntu装opencv error: ‘NppiGraphcutState‘ has not been declared

 ubuntu下安装opencv3.2出现-- ICV: Downloading ippicv_linux_20151201.tgz...

之后就会提示很多错误。

需要自己下载ippicv_linux_20151201.tgz点击打开链接

然后复制替换到opencv-3.2.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e文件下

解决方案：

# 打开问题文件
gedit ~/opencv_contrib/modules/tracking/include/opencv2/tracking/onlineMIL.hpp

# 修改代码
# 找到下面这一行
#define sign(a) a > 0 ? 1 : a == 0 ? 0 : -1

替换为
namespace {
    template
    CV_INLINE int sign(const T v) {
        return (v > 0) ? 1 : ((v < 0) ? -1 : 0);
    }
} // anon namespace

# 然后重新
make -j8
sudo make install -j8

/usr/bin/ld: 找不到 -lippicv

解决方案三：

从opencv.pc中可以看出，pkg-config加载库的路径是/usr/local/lib,我们去这这个路径下看看，发现没有-lippicv对应的库，别的选项都有对应的库，然后我们把-lippicv对应的库（libippicv.a）放到这个路径下就好啦了。
我的liboppicv.a在/home/ds/opencv-3.1.0/3rdparty/ippicv/unpack/ippicv_lnx/lib/intel64这个路径下。你的也在你自己opencv文件夹的对应路径下。
先cd 到上面这个路径下，然后cp liboppicv.a /usr/local/lib 将这个库文件复制到/usr/local/lib下就好了。

再试试，发现“/usr/bin/ld: 找不到 -lippicv
collect2: error: ld returned 1 exit status”这个错误已经解决。

原因解析：

cuda9不再支持2.0架构

解决方案如下：

1）.找到FindCUDA.cmake文件

找到行

find_cuda_helper_libs(nppi)

改为

      find_cuda_helper_libs(nppial)
      find_cuda_helper_libs(nppicc)
      find_cuda_helper_libs(nppicom)
      find_cuda_helper_libs(nppidei)
      find_cuda_helper_libs(nppif)
      find_cuda_helper_libs(nppig)
      find_cuda_helper_libs(nppim)
      find_cuda_helper_libs(nppist)
      find_cuda_helper_libs(nppisu)
      find_cuda_helper_libs(nppitc)

2）.找到行

set(CUDA_npp_LIBRARY "${CUDA_nppc_LIBRARY};${CUDA_nppi_LIBRARY};${CUDA_npps_LIBRARY}")

改为

set(CUDA_npp_LIBRARY "${CUDA_nppc_LIBRARY};${CUDA_nppial_LIBRARY};${CUDA_nppicc_LIBRARY};${CUDA_nppicom_LIBRARY};${CUDA_nppidei_LIBRARY};${CUDA_nppif_LIBRARY};${CUDA_nppig_LIBRARY};${CUDA_nppim_LIBRARY};${CUDA_nppist_LIBRARY};${CUDA_nppisu_LIBRARY};${CUDA_nppitc_LIBRARY};${CUDA_npps_LIBRARY}")

3）.找到行

unset(CUDA_nppi_LIBRARY CACHE)

改为

    unset(CUDA_nppial_LIBRARY CACHE)
    unset(CUDA_nppicc_LIBRARY CACHE)
    unset(CUDA_nppicom_LIBRARY CACHE)
    unset(CUDA_nppidei_LIBRARY CACHE)
    unset(CUDA_nppif_LIBRARY CACHE)
    unset(CUDA_nppig_LIBRARY CACHE)
    unset(CUDA_nppim_LIBRARY CACHE)
    unset(CUDA_nppist_LIBRARY CACHE)
    unset(CUDA_nppisu_LIBRARY CACHE)
    unset(CUDA_nppitc_LIBRARY CACHE)

4）.找到文件OpenCVDetectCUDA.cmake

修改以下几行

     ...
      set(__cuda_arch_ptx "")
      if(CUDA_GENERATION STREQUAL "Fermi")
        set(__cuda_arch_bin "2.0")
      elseif(CUDA_GENERATION STREQUAL "Kepler")
        set(__cuda_arch_bin "3.0 3.5 3.7")
      ...

改为

      ...
      set(__cuda_arch_ptx "")
      if(CUDA_GENERATION STREQUAL "Kepler")
        set(__cuda_arch_bin "3.0 3.5 3.7")
      elseif(CUDA_GENERATION STREQUAL "Maxwell")
        set(__cuda_arch_bin "5.0 5.2")
      ...

5）.cuda9中有一个单独的halffloat(cuda_fp16.h)头文件,也应该被包括在opencv的目录里

将头文件cuda_fp16.h添加至 opencv\modules\cudev\include\opencv2\cudev\common.hpp

即在common.hpp中添加

#include

重新生成即可

cuda9.0原因导致的（make时）：

我的cuda版本是9.0，估计就是版本问题，网上有人说把cuda降到8.0以下。这个方法真是扯淡～

其实只要在编译的时候加一句话就好了

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..

关键就是在最后指定使用Kepler
