Raspberry pi +opencv read camera
Call the camera on the Raspberry Pi, read each frame in the video stream, and use the canny edge detection to extract the edges in each frame, the final effect is as follows:
ReadVideo.cpp
#include "opencv2/opencv.hpp"
using namespace CV;

Raspbian in the desktop environment, the system will go into hibernation after a period of time. Tried some methods such as directly with Xset close DPMS, is not successful.
Raspbian uses a lightweight desktop display manager that is LIGHTDM, which allows you to set up Xserver desktop session interaction \ Display, and so on.
1. Open the terminal;
2. Edit/etc/lightdm/lightdm.conf
3. Locate the ' Xserver-command '

You need to understand the concept of Bitcoin
You need to know the computing power of the Raspberry Pi, which is much less effective than the graphics card mining, the baked cat, the USB mining, etc.
If you want to toss it, come on. 2. Prepare:
You want to dig Bitcoins, first of all to know where to dig Bitcoin, Bitcoin is in a mine, so we register the mine pool account
