The process of training my own data

Open LeeHW-THU opened this issue 2 years ago • 9 comments

Thank you for your work and contribution. I saw that you uploaded the code for COLMAP and it seems to only need the colmap_results/dense/fused.ply file. I'm having trouble making my own dataset, I have a batch of images now, how do I make my transforms_{}.json. the camera_angle_x and rotation in it I don't know where to get from, the transform_matrix seems to be available from COLMAP. Do you have a script to generate these files please? I'm new at this.

I also have the question about how to covert llff format dataset to the dataset as in the nerf_synthetic or nerf_synthetic_colmap. Do you have any hints about this?

It seems that set dataset_name='llff_ft' in the config sh file will lead to xyz_world_all zeros shape. Does the config differ from what is in the dev_scripts/w_n360 ?

hi, the liff_ft is not well developed, so there might be some error. we don't have time to cover liff datasset in our submission.

Thank you so much for your reply! Do you have the plan to cover llff_ft recently?

I think the issue may be related to the 'ranges' in the config. Could you please give me some hints on how to decide the ' ranges' in the config? Thank you so much!

I think the range in the configuration file refers to x_min y_min z_min x_max y_max z_max

hi Lee，i wonder if you solve this problem？ for i also have trouble adding point cloud from external method, do you have any idea? thanks a lot.

hi @Erisnoit . I did make a batch of data, but I got some Loss errors when I entered the data into PointNeRF. I gave up on continuing the experiment because of the poorly commented variables in the code.

I noticed the same thing and realized the same thing as what Lee mentioned x_min y_min z_min x_max y_max z_max.

But I have no idea about how to set these values for my own data. Could you provide some instructions? Thanks! @Xharlie
