大数运算——计算n的阶乘（n>=20）。 （1）数据的表示和存储；  （1.1）累积运算的中间结果和最终的计算结果的数据类型要求是整型——这是问题本身的要求；  （1.2）试设计合适的存储结构，要求每个元素或节点最多存储数据的3位数值。   （2）数据的操作及其实现： 基于设计的存储结构实现乘法操作，要求从键盘上输入n值，在屏幕上显示最终计算结果。

1.首先从文件菜单打开程序目录下的car.avi视频,系统将显示视频的第一帧。 2.点击背景提取菜单，稍后会提取出背景并显示在打开的第二个窗口中。 3.当提取出背景后，点击检测跟踪菜单，对车辆进行检测和跟踪。 4.点击轨迹绘制菜单，绘制车辆的轨迹。 注：由于使用OpenCV打开AVI视频文件需要视频解码器，故在程序运行前请在电脑上先安装DivX类型的的视频解码器，否则将出现无法打开文件的错误。本程序使用的是OpenCV2.1版本，在没有安装此版本软件的机器上运行时需要将cv210.dll,cvaux210.dll,cvcore210.dll,highgui210.dll,ml210.dll这五个文件拷贝至*.exe可执行文件下。(First, open the CR. AVI video from the file menu and the system will display the first frame of the video. 2. Click on the Background extract menu and the background will be extracted later and displayed in the open second window. 3. When the background is extracted, click on the Test Tracking menu to test and track the vehicle. 4. Click on the trajectory drawing menu to map the trajectory of the vehicle. Note: Since a video decoder is required to open an AVI video file using OpenCV, install a DivX-type video decoder on the computer before the program runs, otherwise an error will occur that can not open the file. The program uses OpenCV2 .1, which requires five files to be copied to *, cv210. DLL, cvaux 210. DLL, cvcore 210. DLL, highgui 210. DLL, ML 210. DLL. Exe under executable.)

纯c#项目工具 WGS84 BJ54 Xian80 坐标转换 . c#项目工具，三种坐标可互转，与GDAL计算得出的结果几乎一样，不引用其它类库

用c++语言编程，读取txt文件，并写成.e文件,(Using c++ language programming, reading txt file, and written as. E documents,)

对于labview编程者来说，需要解析hex文件需要额外翻查许多资料，本程序为labview程序，用来解析hex文件(labview program anlysis hex file)

光电编码器，是一种通过光电转换将输出轴上的机械几何位移量转换成脉冲或数字量的传感器。 这是目前应用最多的传感器，光电编码器是由光栅盘和光电检测装置组成。光栅盘是在一定直径的圆板上等分地开通若干个长方形孔。由于光电码盘与电动机同轴，电动机旋转时，光栅盘与电动机同速旋转，经发光二极管等电子元件组成的检测装置检测输出若干脉冲信号(Photoelectric encoder, a photoelectric conversion to the output shaft of the mechanical geometry of displacement into a pulse or digital sensors. This is currently the most widely used sensors, optical encoder is determined by the grating disk and photoelectric detection device component. Grating disc is a circular plate in such a diameter of several rectangular holes partially opened. Because coaxial photoelectric encoder and the motor, the motor rotates, the grating disk rotates with the same speed motor, the light-emitting diodes and other electronic components of the detection device detects certain pulse signal output)

说明：  STM32F407定时器实验，使用定时器控制LED闪烁，并且与while循环的闪烁灯进行时间的对比。(STM32F407 timer experiment uses timer to control LED flicker, and compares the time with that of the while cycle flicker lamp.)

说明：  RRT算法应用于机械臂避障的过程中，具有良好的稳定性(RRT algorithm has good stability in the process of robot arm avoiding obstacles)
