On that note, @19reborn can you please upload the dataset creation code from videos? A script that can take in colmap images and cameras and generate the transform.json. Whenever I have tried using my custom dataset, the reconstructions have failed whereas when I have used the available synthetic data, the reconstructions have been terrific. I think the transform.json might be incorrect in the way, I have been generating them.
Hi, The "transform_matrix" is the camera pose in world space (i.e. the camera2world transformation matrix, also the inverse of extrinsic). btw, NeuS2 also supports data format provided by Instant-NGP, maybe you can try this as well.
hi @wuyingxiong , We use meters as T's unit. You may need to first scale the T according to the unit and then do the inverse operation.
hi @abhishekmonogram , you can follow instant-ngp (https://github.com/NVlabs/instant-ngp/blob/master/docs/nerf_dataset_tips.md) to generate the transform.json from colmap.
@19reborn @wuyingxiong @abhishekmonogram @erin47 @AuthorityWang Hello, I use the instant - NGP (https://github.com/NVlabs/instant-ngp/blob/master/docs/nerf_dataset_tips.md The generated transform.json has only transform_matrix but has no intrinsic_matrix. How can I fix this?
