Ubuntu14.04 Installing opencv3.1 and opencv3.3

Visual Slam 14 speaks of opencv3.1, and opencv3.3 adds to the application of deep learning, so compiling both for the next step of learning and research.

1. Installing opencv3.1

Installation Reference Link: https://docs.opencv.org/3.1.0/d7/d9f/tutorial_linux_install.html

Brief steps:

1.1 Required Packages[compiler] sudo apt-get install build-essential[Required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev Libswscale-dev

[Optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-d EV Libdc1394-22-dev

Make-j7sudo make install2.4 may encounter problems

In CMake. Step, an error occurred while downloading the ippicv_2017u2_lnx_intel64_20170418.tgz file.

The workaround is also manually downloaded and put to the appropriate path, the solution for the problem Reference link: https://github.com/opencv/opencv/issues/8641.
