A short guide to capture custom forward-facing scenes and rendering fly-through videos.
Below are two rgb and depth fly-through videos from custom captured scenes.

Training
$ python run.py --config configs/nerf/lego.py --render_test
Use --i_print
and --i_weights
to change the log interval.
Evaluation
To only evaluate the testset PSNR
, SSIM
, and LPIPS
of the trained lego
without re-training, run:
$ python run.py --config configs/nerf/lego.py --render_only --render_test \
--eval_ssim --eval_lpips_vgg
Use --eval_lpips_alex
to evaluate LPIPS with pre-trained Alex net instead of VGG net.
Render video
$ python run.py --config configs/nerf/lego.py --render_only --render_video
Use --render_video_factor 4
for a fast preview.
Reproduction: all config files to reproduce our results.

Coming soon hopefully.
Adjusting the data related config fields to fit your camera coordinate system is recommend before implementing a new one. We provide two visualization tools for debugging.
--export_bbox_and_cams_only {filename}.npz
:
python run.py --config configs/nerf/mic.py --export_bbox_and_cams_only cam_mic.npz
python tools/vis_train.py cam_mic.npz
--export_coarse_only {filename}.npz
(assumed coarse_last.tar
available in the train log):
python run.py --config configs/nerf/mic.py --export_coarse_only coarse_mic.npz
python tools/vis_volume.py coarse_mic.npz 0.001 --cam cam_mic.npz

We have reported some ablation experiments in our paper supplementary material.
Setting N_iters
, N_rand
, num_voxels
, rgbnet_depth
, rgbnet_width
to larger values or setting stepsize
to smaller values typically leads to better quality but need more computation.
The weight_distortion
affects the training speed and quality as well.
Only stepsize
is tunable in testing phase, while all the other fields should remain the same as training.
You will need them for scaling to a higher grid resolution. But we believe our simplest dense grid could still be your good starting point if you have other challenging problems to deal with.
The code base is origined from an awesome nerf-pytorch implementation, but it becomes very different from the code base now.
