基于C++的简单stun服务器和客户端程序，用于探测客户端与服务器之间的不同NAT类型。Based on c + + simple stun server and the client program, used to detect the different NAT types between client and server.

【实例简介】 Windows 32位版本的CEF3工程代码（需要自己CMake创建sln，自行编译产生cefsimple/cefclient）。Chromium版本：78.0.3904.108。编译时加入ffmpeg支持，可以播放mp3, mp4, 支持h.264/aac。

组网的基本知识以及无人机数据链组网、点对点组网、IP组网的原理框图及说明(principle of IP network convergence)

说明：  通过电脑与机器人进行人机交互，给出相应的控制指令（比如停止、前进等），伺服驱动的PID对伺服电机进行初步控制，伺服电机的测量信号反馈给开放式多轴运动控制器，然后该控制器的PID会对系统进行再次细调，使伺服电机运行得更平稳，从而完成控制人员对轮式机器人的各种操作指令。(Through human-machine interaction between computer and robot, corresponding control instructions (such as stop, advance, etc.) are given. Servo-driven PID controls the servo motor initially, and the measurement signal of the servo motor is fed back to the open multi-axis motion controller. Then the PID of the controller will fine-tune the system again, making the servo motor run more smoothly, thus completing the control personnel. Various operating instructions for wheeled robots.)

说明：  基于WinSock的UDP数据转发(Win XP；Visual C++ 6.0)(WinSock based on the UDP data transmitted (Win XP; Visual C 6.0))

该算法实现了基于纹理特征的稀疏表示分类，代码注释清晰，容易理解(The algorithm implements the sparse representation based on texture features, and the code is clear and easy to understand.)

说明：  Socket服务端与客户端通信demo。(Socket server communicates with client demo.)
