Documentation on the LLFF data scene?

[franciscoWizz]

Hi Chen-Hsuan,

Do you have any documentation regarding how to set up another scene experiment? I did not found anything on the readme nor in the paper.

I'm refering to this folders and files:

Thanks in advance,

Hi @franciscoWizz, if you'd like to use your own sequence for BARF, you can create another data Python file (in data) to load your sequence. You can check out data/iphone.py as an example. If you want to use exactly the same data format as provided in LLFF scenes, please see the original NeRF repo for instructions.

Hi @chenhsuanlin,

Indeed I want to get the estimated camera poses out of a set of pictures. I'll take a look at the file you mention and come back if I have any question.

Thanks,

@chenhsuanlin,

When specifying the pictures dimensions I found that in the line #20 you assigned a particular size (1080, 1920):

2 questions about it:

1. Does the model need that all the pictures be equally sized?
2. Do I need to change the size read in line camera pose refinement starting from relatively correct initial poses instead of identity transformation matrices #20 with my images size? or this parameter is assigned in the command line options?

Thanks in advance

Hi @franciscoWizz, for now we assume that the incoming frames from the sequence are all equally sized and specified in self.raw_H and self.raw_W. The yaml files specify how you would want to resize your images (opt.data.image_size), which would rescale your intrinsic parameters accordingly. Hope this helps!
