Folders

  • data/maps (>80Mb)

point cloud maps and images with resolution of 0.25m/pixel

We have uploaded the radar scan images of Seq02 on Google Drive.

  • data/gt_poses

groud truth poses for evaluation

  • data/odom

odometry data via ICP

  • ekf_filter

differetiable ekf implementation

  • loader

dataLoader for training and inference

  • loss

cross entropy loss (L1) and squared error loss (L2)

  • models

Pre-trained models of RaLL

  • network

feature extraction network and patch network

  • test_py

test pose tracking on RobotCar and MulRan

To train RaLL

Please use the train_rall_L12.py and train_rall_L3.py. Please modify the data path in the python files.
