neuris's Introduction

NeuRIS

We propose a new method, dubbed NeuRIS, for high quality reconstruction of indoor scenes.

Data preparation

Scene data used in NeuRIS can be downloaded from here and extract the scene data into folder dataset/indoor. And the scene data used in ManhattanSDF are also included for convenient comparisons. The data is organized as follows:

<scene_name>
|-- cameras_sphere.npz   # camera parameters
|-- image
    |-- 0000.png        # target image for each view
    |-- 0001.png
    ...
|-- depth
    |-- 0000.png        # target depth for each view
    |-- 0001.png
    ...
|-- pose
    |-- 0000.txt        # camera pose for each view
    |-- 0001.txt
    ...
|-- pred_normal
    |-- 0000.npz        # predicted normal for each view
    |-- 0001.npz
    ...
|-- xxx.ply		# GT mesh or point cloud from MVS
|-- trans_n2w.txt       # transformation matrix from normalized coordinates to world coordinates

Refer to the file for more details about data preparation of ScanNet or private data.
