5. Development tools, environment, build executables

Some development tools are needed with this package, listed below:

5.1 Notes for developers

You can use the main.py for execute as first time in src/ak_frameextractor/ main _.py Configure the path of the project, if you use Pycharm, put your folder root like this: ak_frame_extractor

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 package.whl

5.4.3 Run ak_frame_extractor

python -m ak_frame_extractor.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_frame_extracted_f/ or a compressed file "ak_frame_Extractor_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/

abstract = {The emergence of low-cost 3D sensors, and particularly RGB-D cameras, together with recent advances in artificial intelligence, is currently driving the development of in-field methods for fruit detection, size measurement and yield estimation. However, as the performance of these methods depends on the availability of quality fruit datasets, the development of ad-hoc software to use RGB-D cameras in agricultural environments is essential. The AKFruitData software introduced in this work aims to facilitate use of the Azure Kinect RGB-D camera for testing in field trials. This software presents a dual structure that addresses both the data acquisition and the data creation stages. The acquisition software (AK_ACQS) allows different sensors to be activated simultaneously in addition to the Azure Kinect. Then, the extraction software (AK_FRAEX) allows videos generated with the Azure Kinect camera to be processed to create the datasets, making available colour, depth, IR and point cloud metadata. AKFruitData has been used by the authors to acquire and extract data from apple fruit trees for subsequent fruit yield estimation. Moreover, this software can also be applied to many other areas in the framework of precision agriculture, thus making it a very useful tool for all researchers working in fruit growing.}
