# Opencv_Compile

### Opencv 源码编译安装

### 安装Nvidia驱动
1. 集用nouveau驱动
```
sudo gedit  /etc/modprobe.d/blacklist-nouveau.conf


blacklist nouveau

options nouveau modeset=0

sudo update-initramfs -u

sudo reboot

```
2. 安装cc

```
sudo apt-get install gcc

sudo apt-get install g++

```

3. 安装make

```
sudo apt-get install make
```

4. 安装cmake
```
sudo apt-get install cmake
```


5. 安装驱动
```
sudo bash NVIDIA*.sh
```


### 安装CUDA和CUDNN

cuda 安装

```
sudo bash cuda_10.0.130_410.48_linux.run
```
cuda 环境配置

```
sudo gedit ~/.bashrc

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

source ~/.bashrc
```
> 使用nvcc -V 验证是否安装成功

cudnn 安装

```
sudo cp cuda/include/cudnn.h /usr/local/cuda/include/

sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/

```
> 使用cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2 来验证是否安装成功



### 编译opencv 

拷贝项目到指定位置
```
cp -r opencv-4.1.2  ~/Code/opencv-4.1.2
cp -r opencv-contrib-4.1.2 ~/Code/opencv-contrib-4.1.2
```

安装依赖项
```
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 python3-dev python3-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev
sudo apt-get install qt5-default


```
libjasper

```
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev

```




使用cmake-gui打开

```


sudo rm /usr/lib/x86_64-linux-gnu/libEGL.so

sudo ln /usr/lib/x86_64-linux-gnu/libEGL.so.1 /usr/lib/x86_64-linux-gnu/libEGL.so

sudo rm /usr/lib/x86_64-linux-gnu/libGL.so

sudo ln /usr/lib/x86_64-linux-gnu/libGL.so.1 /usr/lib/x86_64-linux-gnu/libGL.so

```


cmake中设置
```
-D WITH_CUDA=ON

-D OPENCV_EXTRA_MODULES_PATH=/home/samples/Code/opencv_contrib-4.1.2/modules

-D CUDA_ARCH_BIN=7.5

-D WITH_QT=ON

-D BUILD_opencv_python3=ON

-D PYTHON3_EXECUTABLE=/usr/bin/python3

-D PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.6m.so

-D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3/dist-packages/numpy/core/include/numpy

-D BUILD_opencv_cudacodec=OFF
```
> cmake中无法正确显示python3的libraries

终端设置
```
cmake -D WITH_CUDA=ON -D OPENCV_EXTRA_MODULES_PATH=/home/samples/Code/opencv_contrib-4.1.2/modules -D CUDA_ARCH_BIN=7.5 -D WITH_QT=ON -D BUILD_opencv_python3=ON -D PYTHON3_EXECUTABLE=/usr/bin/python3 -D PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.6m.so -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3/dist-packages/numpy/core/include/numpy ..
