Pre-trained model

Pre-trained models can be downloaded from google drive

Evaluation

1. Download KITTI odometry dataset.
2. Change the path to the dataset in evaluate_calib.py.

data_folder = '/path/to/the/KITTI/odometry_color/'

3. Create a folder named pretrained to store the pre-trained models in the root path.
4. Download pre-trained models and modify the weights path in evaluate_calib.py.

weights = [
   './pretrained/kitti_iter1.tar',
   './pretrained/kitti_iter2.tar',
   './pretrained/kitti_iter3.tar',
   './pretrained/kitti_iter4.tar',
   './pretrained/kitti_iter5.tar',
]

5. Run evaluation.

python evaluate_calib.py

Train

python train_with_sacred.py
