Coco dataset

[1z2213]

Hi, thank you very much for your great work！
What should I do if I want to train the coco dataset, after all the Megadepth dataset is too big!
I think first use superpoint to export the coco dataset detections to generate a series of npz files, then execute the command python3 -m dump.dump_megadepth --feature_type spp --base_path path_of_megadepth --save_ path your_save_path, is this correct?
Looking forward to your reply！

Hello,

Sorry for the late reply.

For training on coco dataset, a better way is to generate paired images online with perspective projection function in opencv. I have tried the training on coco only, but the performance is not very good.

I will try to provide the training scripts on coco.

你好

对不起，回复晚了。

对于coco数据集的训练，更好的方法是在opencv中使用透视投影功能在线生成配对图像。我只尝试过coco的训练，但表现不是很好。

我会尝试在 coco 上提供训练脚本。

Thank you very much for your reply.
Since my own training dataset is similar to coco, I need your training code for training coco. Looking forward to your training scripts!
