| 3 ---- | |
| 4 ## usage | |
| 5 1. Make sure your data is structured like so: | |
| 6 ``` | |
| 7 Data # Folder containing all the data | |
| 8 └── <Intersection name> # Intersection (e.g. montcalm-chartwell) | |
| 9 ├── <tracking configuration file>.cfg | |
| 10 ├── <Date 1> | |
| 11 │ ├── <Other subdirectories> # There can be as many subdirectories as you want | |
| 12 │ ├── <Video 1> | |
| 13 │ ├── <Ground truth database 1>_gt.sqlite | |
| 14 │ ├── homography.txt | |
| 15 │ ├── image.pg | |
| 16 │ ├── mask.png | |
| 17 │ └── point-correspondences.txt | |
| 18 ├── <Date 2> | |
| 19 └── <Date 3> | |
| 20 . | |
| 21 . | |
| 22 . | |
| 23 ``` | |
| 24 | |
| 25 > Please note : You should have at least one ground truth database (with a name ending with "_gt.sqlite") for each date of the intersection. | |
| 26 | |
| 27 2. Select an intersection or several intersections for which you wish to find optimal tracking parameters, for instance: | |
| 28 | |
| 29 $ python3 optimize-with-nomad.py -t /media/disk2/etienne/Data/montcalm-chartwell/ /media/disk2/etienne/Data/montcalm-victorin/ --optimize-grouping-only | |
| 30 | |
| 31 > Please note : You cannot find the optimal parameters only for the grouping algorithm if there is not a database already created. You should first execute the tracking algorithm with basic parameters. | |
| 32 | |
| 33 3. Once the optimal parameters are found, tracking may be launched: | |
| 34 | |
| 35 $ cd $HOME/Data/montcalm-chartwell | |
| 36 $ feature-based-tracking tracking-visible.cfg --tf --video-filename 2019-11-27/Visible/2019-11-27T12\:20-05\:00.MP4 --database-filename 2019-11-27/Visible/2019-11-27T12\:20-05\:00.sqlite --homography-filename 2019-11-27/Visible/homography.txt --mask-filename 2019-11-27/Visible/mask.png --feature-quality 0.1 --min-feature-distanceklt 3.54964337411 --window-size 6 --min-tracking-error 0.01 --min-feature-time 15 | |
| 37 $ feature-based-tracking tracking-visible.cfg --gf --video-filename 2019-11-27/Visible/2019-11-27T12\:20-05\:00.MP4 --database-filename 2019-11-27/Visible/2019-11-27T12\:20-05\:00.sqlite --homography-filename 2019-11-27/Visible/homography.txt --mask-filename 2019-11-27/Visible/mask.png --mm-connection-distance 2 --mm-segmentation-distance 1.9 --min-nfeatures-group 4 | |
