The way to employ BA for fine-tuned VGGT

[Wangweizhen-S]

Thanks for your excellent work. I‘m trying to finetuing VGGT on a certain dataset which lacks texuture. After getting a good initial pose and depth, I want to use BA to refine the result further. However, it will probably fails in the way using VGGSfm to extract corresponding points as the demo_colmap.py shows for the dataset's intrinsic properties. So, I wonder, how to use the track head in VGGT(I will fine tune on my dataset) to get the corresponding points beacuse the VGGT track head's input seemly are certain query points while the matched feature points are computed. Looking forward for your reply. Thanks!

Here's one more question: The final goal I want to realize is to reconstruction mesh, is there any method to align the pointpoint results for mesh reconstruction

@Wangweizhen-S Hello dear! I just started working on this project after reading all the repository. I couldn't find the dataset preparation scripts for all datasets. If you have some dataset scripts, please share them with me (tas25@yahoo.com). It will be very helpful for me to train a model on it. Thanks
