 ### 3. Then, use this [script](https://github.com/zju3dv/object_nerf/blob/main/data_preparation/scannet_sens_reader/convert_to_nerf_style_data.py) to convert the data to NeRF-style format. For instructions, see Step 1 [here](https://github.com/zju3dv/object_nerf/tree/main/data_preparation).
-	1. The generated transforms_xxx.json comes with transformation matrix (from camera coordinate to world coordinate) in SLAM / OpenCV format (xyz -> right down forward). You need to change to NDC format (xyz -> right up back) in the dataloader for training with NeRF convention.
