Move the Tello-Python sample "Tello_Video"

This is a supplementary page of.

I mean, not only for "Tello_Video", If you want to do "Tello-Python" on Windows, you need to do this first, including installing Python.

Overview

Of the DJI official Python sample program "Tello-Python" for Tello 　Tello_Video In order to try

--Installation of various dependent libraries

You need to do.

As an installation method, git's Tello-Python page

・ Windows

Go to the "install\Windows" folder,select and run the correct "windows_install.bat" according to your computer operating system bits.

is what it reads. That is,

`Move folders, change file attributes, execute shell files`


> cd install¥Windows¥
> windows_install.bat

And type the command. ** windows_install.bat ** is a batch file that automatically builds the environment for Windows.

But even if you do this

--The specified Python version is 2.7.15. I want to install the final version 2.7.17 anyway --In automatically installed Python, pip cannot be used at the command prompt, so you need to manually install it again. --The specified ffmpeg version is old and the file does not exist, so it cannot be downloaded. --Boost download does not work and an error occurs --Visual Studio runtime download does not work and an error occurs ――Since MD5 of the downloaded file is checked one by one, it is difficult to correspond to different versions.

Well, there are a lot of bugs / troubles. Various work is required to solve this.

Prerequisites

Tello-Python is installed in your home folder (c: \ Users \ (user name) ), That is, we will assume that there is a folder called c: \ Users \ (user name) \ Tello-Python-master.

Also,

--Start Windows Command Prompt --Changing the character code of the text file (actually the BAT file)

It is also a major premise that you have the skills to understand. Windows is convenient, but if you try to do something strange, it's a tough environment (> _ <

Move folder

First, in Explorer, move to the install \ Windows folder in Tello-Video. Inside the folder are ʻinstall.bat and ʻuninstall.bat. ** Please note that using this install.bat will not work. **

Using this folder as a work area, we will perform the following tasks.

Create a new BAT file

Windows BAT files do not work well unless the character code is Shift-JIS. (I hate Windows because of this annoyance)

** Copy and paste the following code into Notepad, select [File]-[Save As], and select [Character Code]-[ANSI] to save. ** If you are using any text editor, save it with [Shift-JIS]. The file name is ʻinstall_new2020Mar12.bat`.

For the time being, the file is also placed on github, but the character code is UTF-8. ， Cannot be used as it is. Please convert the character code to [Shift-JIS].

`install_new2020Mar12.bat`

By manually downloading these files, you can prevent execution errors in the bat file.

Execute BAT file

It should look like this in the folder where all the files have been downloaded. (For 64bit)

Then, double-click ʻinstall_new2020Mar12.bat` to start the installation.

Install Python
Install pip
Install boots
Install ffmpeg
Install Microsoft runtime
pip installation of numpy, matplotlib, opencv-python, pillow
Copy of dll

Is done automatically.

If the installation is successful, the command prompt screen will be displayed as shown below.

** If the command prompt closes in an instant, it has failed because the character code is not Shift-JIS. **

After the installation is complete, ** restart your PC **. The environment variables have been added so that they can be enabled.

Manual reinstallation of Python

When the installation is completed with the BAT file, at the command prompt

`python`


>pip install module name

Even if you type, it will be "File does not exist".

Then, double-click python-2.7.17.amd64.msi (for 64bit) to start the installer.

As shown in the figure below, enable "Add python.exe to Path" and reinstall.

Run Tello_Video

To execute "Tello_Video", at the command prompt

`python`


> python main.py

You can type, but A convenient part of Windows is [Execute Association]. Double-click main.py as shown in the figure below to execute the program.

The execution screen will appear like this. Details are explained in Running the Tello-Python sample "Tello_Video".
