在docker容器中安装opencv2.4.11

参考：使用docker交叉编译opencv2.4.9

如果是更新的版本的opencv，可以先到dockerhub上找找是否有可用的镜像

• docker pull ubuntu:16.04

• docker images

• docker run -t -i ubuntu:16.04 /bin/bash (创建、启动、进入容器中)

• mv /etc/apt/sources.list /etc/apt/sources.list.bak

• apt-get update

• apt install vim unzip

• vim /etc/apt/sources.list (注意：apt源要与ubuntu版本对应)
