Collection of ready-to-use commands based on ArGaze toolkit.

.. note::
   *Consider that all inline commands below needs to be executed into ArGaze root folder.*

.. note::
   *Use -h option to get command arguments documentation.*

# ArUco Markers factory

Export all markers from *DICT_APRILTAG_16h5* dictionary as 5 cm pictures with 300 dpi resolution into an *./src/argaze/utils/_export/markers* folder:

```
python ./src/argaze/utils/aruco_markers_dictionary_export.py DICT_APRILTAG_16h5 -s 5 -r 300 -o ./src/argaze/utils/_export/markers
```

Export a 7 columns and 5 rows calibration board made of 5cm squares with 3cm markers from *DICT_APRILTAG_16h5* dictionary at 300 dpi into an *./src/argaze/utils/_export* folder:

```
python ./src/argaze/utils/aruco_calibration_board_export.py 7 5 5 3 DICT_APRILTAG_16h5 -r 300 -o ./src/argaze/utils/_export
```

# Camera calibration

Calibrate a camera device (-d DEVICE) using a 7 columns and 5 rows calibration board made of 5cm squares with 3cm markers from *DICT_APRILTAG_16h5* dictionary. Then, export its optical parameters into an *calibration.json* file into *./src/argaze/utils/demo_environment/* folder:

```
python ./src/argaze/utils/camera_calibrate.py 7 5 5 3 DICT_APRILTAG_16h5 -d DEVICE -o ./src/argaze/utils/demo_environment
```

.. note::
   Use **A3_DICT_APRILTAG_16h5_3cm_35cmx25cm.pdf** file located in *./src/argaze/ArUcoMarkers/utils/* folder ready to be printed on A3 paper sheet.

# AR environment demonstration

Load AR environment from **setup.json** file, detect ArUco markers into camera device (-d DEVICE) frames and estimate envirnoment pose.

```
python ./src/argaze/utils/demo_ar_features_run.py ./src/argaze/utils/demo_environment/setup.json -d DEVICE
```

.. note::
   This demonstration assumes that camera calibration step is done and a **calibration.json** has been exported into *./src/argaze/utils/demo_environment/* folder.

.. note::
   Use **A3_demo.pdf** file located in *./src/argaze/utils/demo_environment/* folder ready to be printed on A3 paper sheet.

# Gaze features demonstration

Simulate gaze position using mouse pointer to illustrate gaze features.

```
python ./src/argaze/utils/gaze_analysis.py ./src/argaze/utils/demo_environment/setup.json
```
