Collection of command-line high level features scripts.
!!! 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 -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/demo_gaze_features_run.py
```
# Heatmap demonstration
Simulate gaze position using mouse pointer to produce heatmap picture.
A picture is saved by pressing escape key.
```
python ./src/argaze/utils/demo_heatmap_run.py
```
