Jetson一键安装opencv4.1.0+opencv4.1.0_contrib

突然想着装一个OPENCV4.1顺便写个记录 

温馨提示：网不行的话就先把这几个文件git pull下来

git clone https://github.com/Unlicensed-driver-ljx/opencv_contrib_essential_module.git

/opencv_contrib-4.1.0/modules/xfeatures2d/src

 放到你的这个目录下再编译，一般有上网方法的同学可以略过

sudo apt-get purge libopencv*

looking for ccache --not found

sudo apt-get install ccache

sudo apt-get install libtesseract-dev

下面的脚本installopencv41.sh和创建的OPENCV放一个目录就好了
mkdir OPENCV
举个例子遇到同学不知道脚本的意思

if [ "$#" -ne 1 ]; then
    echo "Usage: $0 "
    exit
fi
folder="$1"
这里的执行方式是你的脚本改成可执行权限以后，

sudo chmod 777 installopencv41.sh 

sudo ./installopencv41.sh 你的新建的目录（可以是新建的任何名称比如：opencv41）

#!/bin/bash

#Before installing on Nano need to increase memory. Can use swapfile to virtually increase.
#Run these commands to add swap file

if [ "$#" -ne 1 ]; then
    echo "Usage: $0 "
    exit
fi
folder="$1"

echo "** Install requirement"

#（注意 -D OPENCV_GENERATE_PKGCONFIG=ON 这个选项非常重要，会生成一个被pkg-config模块使用的opencv4.pc文件，编译opencv的c++项目时可能会用到，有得同学安装完编译qt项目遇到所以补充了一下）
