## Scene Segmentation on S3DIS
|
||
|
|
|
||
|
|
### Data
|
||
|
|
|
||
|
|
We consider our experiment folder is located at `XXXX/Experiments/KPConv-PyTorch`. And we use a common Data folder
|
||
|
|
loacated at `XXXX/Data`. Therefore the relative path to the Data folder is `../../Data`.
|
||
|
|
|
||
|
|
SemanticKitti dataset can be downloaded <a href="http://semantic-kitti.org/dataset.html#download">here (80 GB)</a>.
|
||
|
|
Download the three file named:
|
||
|
|
* `data_odometry_velodyne.zip`, [`data_odometry_velodyne.zip`](http://www.cvlibs.net/download.php?file=data_odometry_velodyne.zip)
|
||
|
|
|
||
|
|
uncompress the data and move it to `../../Data/S3DIS`.
|
||
|
|
|
||
|
|
http://www.cvlibs.net/download.php?file=data_odometry_velodyne.zip
|
||
|
|
|
||
|
|
|
||
|
|
N.B. If you want to place your data anywhere else, you just have to change the variable
|
||
|
|
`self.path` of `S3DISDataset` class ([here](https://github.com/HuguesTHOMAS/KPConv-PyTorch/blob/afa18c92f00c6ed771b61cb08b285d2f93446ea4/datasets/S3DIS.py#L88)).
|
||
|
|
|
||
|
|
### Training
|
||
|
|
|
||
|
|
Simply run the following script to start the training:
|
||
|
|
|
||
|
|
python3 training_S3DIS.py
|
||
|
|
|
||
|
|
Similarly to ModelNet40 training, the parameters can be modified in a configuration subclass called `S3DISConfig`, and the first run of this script might take some time to precompute dataset structures.
|
||
|
|
|
||
|
|
|
||
|
|
### Plot a logged training
|
||
|
|
|
||
|
|
When you start a new training, it is saved in a `results` folder. A dated log folder will be created, containing many information including loss values, validation metrics, model checkpoints, etc.
|
||
|
|
|
||
|
|
In `plot_convergence.py`, you will find detailed comments explaining how to choose which training log you want to plot. Follow them and then run the script :
|
||
|
|
|
||
|
|
python3 plot_convergence.py
|
||
|
|
|
||
|
|
|
||
|
|
### Test the trained model
|
||
|
|
|
||
|
|
The test script is the same for all models (segmentation or classification). In `test_any_model.py`, you will find detailed comments explaining how to choose which logged trained model you want to test. Follow them and then run the script :
|
||
|
|
|
||
|
|
python3 test_any_model.py
|
