Preface
The Raspberry Pi official has provided an image list: Http://www.raspbian.org/RaspbianMirrors, but because of the server in foreign countries, we install and update the software is always not satisfactory speed, and sometimes a time-out connection caused the installation failure.So there are some mirror stations, such as Ali Open source image, NetEase open source image, China University of Science

It is important to note that the Raspberry Pi will only output to the HDMI port when the display device is checked at boot time, so the monitor must be connected to the HDMI interface before booting. On the left, there is a display of the line port. Given the wide use of HDMI, the outlet is not very high. Below the left is a Micro SD card socket. This SD card replaces the hard drive in th

This assumes that you already have the Raspberry Pi 2/b+, and that it is already installed. If not, I suggest you buy one, they are both cheap and fun.
Personally, I'd rather spend a little more money buying from Canakit. Their logistics quickly and reliably, plus their ready-to-go service is also very good.
Okay, let's start OpenCV and Python installation.Step 0:
