1. Pre-requisites

• Azure Kinect DK camera connected to the computer. Specifications can be seen in the manufacturer site.
• SDK Azure Kinect installed.
• pyk4a library installed. If the operating system is Windows, follow this steps. You can find test basic examples with pyk4a here.
• In Ubuntu 20.04, we provide a script to install the camera drivers following the instructions in azure_kinect_notes.

2. Functionalities

The functionalities of the software are briefly described. Supplementary material can be found in USER's Manual.

• [Show real time] Display images of the device in real time. Used to see where the camera is pointing.
• [Start record] Start a video recording.
• [Stop record] Stops a video recording in progress.
• [Take screenshots] Take screenshots and save them in Matroska format as short videos.
• [Take 3D point cloud capture] Take the captures as 3D point cloud data and save them in .XYZ format.
• [Save config] Enables to the user to configure Azure Kinect devices parameters.
• Videos and 3D cloud points can be retrieved from "RECORDER_VIDEOS/" folder.

3. Install and run

3.1 PIP quick install package

Create your Python virtual environment.

python3 -m venv ./ak_sm_recorder_venv
source ./ak_sm_recorder_venv/bin/activate
pip install --upgrade pip

5.2 Creating virtual environment Linux

python3 -m venv ./venv
source ./venv/bin/activate
pip install --upgrade pip
pip install -r requirements_linux.txt

5.3 Creating virtual environment Windows

%userprofile%"\AppData\Local\Programs\Python\Python38\python.exe" -m venv ./venv
venv\Scripts\activate.bat
pip install --upgrade pip
pip install -r requirements_windows.txt

** If there are some problems in Windows, follow this **

pip install pyk4a --no-use-pep517 --global-option=build_ext --global-option="-IC:\Program Files\Azure Kinect SDK v1.4.1\sdk\include" --global-option="-LC:\Program Files\Azure Kinect SDK v1.4.1\sdk\windows-desktop\amd64\release\lib"

5.4 Building PIP package

We are working to offer Pypi support for this package. At this time this software can be built by scripts automatically.

5.4.1 Build packages

py -m pip install --upgrade build
build_pip.bat

5.4.2 Download PIP package

pip install ak_sm_recorder-1.0-py3-none-any.whl

5.4.3 Run ak_sm_recorder

python -m ak_sm_recorder.py

5.4 Building .EXE for Windows 10

build_win.bat

After the execution of the script, a new folder will be generated inside the project "/dist". You can copy ** ak_sm_recorder_f/** or a compressed file "ak_sm_recorder_f.zip" to distribute.

5.6 Package distribution format

Explain about packages distribution.

Package type	Package	Url	Description
Windows	.EXE	.EXE	Executables are stored under build/
Linux	.deb	.deb	NOT IMPLEMENTED YET
PIP	.whl	.whl	PIP packages are stored in build/
