How to prepare my dataset? #40

Open lazyDamon opened 1 year ago

lazyDamon commented 1 year ago

Hi, thank for your great work! I tried to inference on my own data, but result was very bad. Can you tell me how to prepare my data? I have extrinsics and intrinsics by colmap.

Hello. Since the sparseneus is only trained on the DTU, which is relatively small dataset and may have domain gap with your data. To prepare a custom dataset, you should first rescale the object of the interest into a unit sphere (-0.5, 0.5), and get its multiple images with camera intrinsics extrinsics.

I tried converting my data to DTU format by Neushttps://github.com/Totoro97/NeuS/tree/main/preprocess_custom_data. Then I run SparseNeus, but result is bad. In the same way, it is no problem with using data for other projects.

Hi there, Can you provide a detailed explanation on how to create a custom dataset for training Sparseneus? I have a collection of images along with their corresponding camera intrinsics and extrinsics. Thanks!!

Hi, I ran into the same problem. Do you have any ideas to solve it? Thanks!
