使用前务必仔细阅读此文件！

开发环境

操作系统：Ubuntu 16.04
OpenCV版本：OpenCV-3.4.5

一、安装OpenCV

由于只有OpenCV 3.0以后的版本才有目标跟踪的功能，自从进入3.X时代以后，OpenCV将代码库分成了两部分，分别是稳定的核心功能库和试验性质的contrib库。下面是OpenCV + Contrib的编译与安装过程。

1.下载OpenCV和Contrib：

Contrib没有在OpenCV的官网发布，而是发布在了OpenCV的github上，需要注意的是OpenCV和Contrib的版本要对应，不然无法编译安装。OpenCV和Contrib的源代码都可以在OpenCV的github上下载到，下载连接：

2.编译安装：

准备，先安装以下依赖包：

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  

sudo apt-get install build-essential qt5-default ccache libv4l-dev libavresample-dev  libgphoto2-dev libopenblas-base libopenblas-dev doxygen  openjdk-8-jdk pylint libvtk6-dev

sudo apt-get install pkg-config

编译：

（1）解压下载好的源代码：

sudo unzip opencv-3.3.1.zip
sudo unzip opencv_contrib-3.3.1.zip

（2）解压完后需要将opencv_contrib.zip提取到opencv目录下，同时在该目录下新建一个文件夹build：

sudo cp -r opencv_contrib-3.3.1 opencv-3.3.1  #复制opencv_contrib到opencv目录下

cd opencv-3.3.1

sudo mkdir build                              #新建文件夹build

（3）进入build目录，并且执行cmake生成makefile文件：

sudo cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/home/user_name/opencv-3.4.3/opencv_contrib-3.4.3/modules/ ..

注意：OPENCV_EXTRA_MODULES_PATH就是 opencv_contrib-3.3.1下面的modules目录，请按照自己的实际目录修改地址。接下来就是漫长的等待了……

（4）在cmake成功之后，就可以在build文件下make了：

make

接下来就是更漫长的等待了……make成功后再执行make install就ok了！

（5）链接库共享：

编译安装完毕之后，为了让你的链接库被系统共享，让编译器发现，需要执行管理命令ldconfig：

sudo ldconfig -v

Ubuntu16.04会报错：

解决办法：

sudo apt-get autoremove libtiff5-dev
sudo apt-get install libtiff5-dev

3.测试

# 进入opencv-2.4.13/samples/c/example_cmake
cd opencv-2.4.13/samples/c/example_cmake
# 编译
cmake
make
# 编译之后会生成可执行文件opencv_example，运行
./opencv_example
# 运行结果为摄像头拍摄并在画布上显示hello opencv

二、编译源代码

首先下载源代码，并解压，进入解压后的目录。新建build目录并进入build：

mkdir build
cd build

然后用cmake进行编译：

cmake ../src/
make

make命令执行成功后会在build目录下生成bin文件夹，进入bin文件夹就可以运行可执行文件了。首先要下载已经训练好的caffe模型，并放在bin目录下，已经下训练好的模型链接如下：链接：https://pan.baidu.com/s/1nq9g4l3ttNm5qBU0pJA64Q 提取码：j3td 同时，这个链接中也包含了两个演示视频。然后运行以下命令运行程序：

./run -p ../parameters.yml -s ../datasets/06_car/car.mpg    # -p用来指定tld算法的参数文件 -s选项用来选择传入的视频文件，可以连续输入多个视频做跨摄像头目标跟踪
