DirectionNet

This repository will contain the TensorFlow code for the model introduced in the CVPR 2020 paper:

Wide-Baseline Relative Camera Pose Estimation with Directional Learning \ Kefan Chen, Noah Snavely, Ameesh Makadia \ IEEE Conference on Computer Vision and Pattern Recognition (CVPR 2020). \ arXiv

Requirements

Required packages: tensorflow 1.15, tensorflow_graphics, tensorflow_addons, tensorflow_probability, tf_slim, pickle

Dataset and Pre-trained Models

MatterportA test data\ MatterportB test data

1. dataset.generate_from_meta can create the datasets of images and ground truth from the Matterport3D dataset given the meta data files.

2. dataset.generate_random_views can be used to generate a large-scale wide stereo dataset with camera pose labels from a panoramic image dataset.

Train DirectionNet-R and DirectionNet-T

1. train DirectionNet-R.

   python train.py \
   --checkpoint_dir <path_to_checkpoints_and_logs> \
   --data_dir <path_to_training_set> \
   --model 9D

2. Run DirectionNet-R on the training and test sets, then save the estimated rotations as Python pickle dictionary in the data directories respectively.
3. train DirectionNet-T.

   python train.py \
   --checkpoint_dir <path_to_checkpoints_and_logs> \
   --data_dir <path_to_training_set> \
   --model T

Evaluation

--eval_data_dir <path_to_test_set> \
--save_summary_dir <path_to_save_logs> \
--testset_size <testset_size> \
--batch <test_batch> \
--model 9D

DirectionNet-T

python eval.py \
