樹莓派opencv的安裝

樹莓派安裝opencv的教程層出不窮，但是能用的很少。我這個教程是親自安裝成功的。

我之前安裝過好幾次opencv2.49都失敗了，唯獨這個opencv3.1成功了。

下面開始安裝吧

1.準備

sudo apt-get install build-essential git cmake pkg-config

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 libjpeg-dev libjasper-dev libdc1394-22-dev

sudo apt-get install libjpeg8-dev

sudo apt-get install libtiff5-dev

sudo apt-get install libjasper-dev

sudo apt-get install libpng12-dev

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

sudo apt-get install libatlas-base-dev gfortran

2.下載opencv

cd /home/pi

git clone https://github.com/Itseez/opencv.git

cd opencv

git checkout 3.0.0

3.安裝opencv_contrib：

cd /home/pi

git clone https://github.com/Itseez/opencv_contrib.git

cd opencv_contrib

git checkout 3.0.0

4.安裝python

sudo apt-get install python2.7-dev

5.安裝opencv

進入opencv3.1資料夾

cmake .  # cmake+空格+"."

sudo make

sudo make install

sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'

sudo ldconfig

6.編譯sample

cd ~/opencv/samples

sudo cmake .

sudo make -j $(nproc)

7.執行測試程式

進入opencv3.1資料夾

cd samples

cd cpp/

./cpp-example-facedetect lena.jpg

我在網上找了個圖片， 進行測試。
