How to annotate panorama

[dengzhijie]

Hello
First, thanks for your sharing .
We want to use new indoor panorama samples for training, but how to annotate panorama as shown in the appendix becomes a trouble for us. Could you share the method or some tools to do the work?
Thank you!

Hi,
You could try https://github.com/SunDaDenny/PanoAnnotator which is developed in python.
You should get the corner position on the image annotated by above tool.
Constructing boundary/corner probability map from corner position is simple in mathematic.

Good luck ;)

Really thanks for your reply!
I will try this way later.In addition,I have another question to consult you.When I use the official model to process panoramic pictures，sometimes we get the result of a corner migration as shown in the annex. How can I get a better result?Can I get a good result after 3D layout optimization?
Thanks much!
Good luck

Hi @dengzhijie
Maybe you could try flipping/horizontal rotation as testing augmentation first.
I suggest flipping, clip right most 33% to left, clip right most 66% to left. After getting the result of each augmented version, undo augmentation and take the mean.
You could reference LayoutNet papers Table1,2,3 for some benchmark of 3D optimization.

@sunset1995 Thanks! 👍 :)

I have got the corner id position, but I don't know how to get the boundary/corner probability map like the dataset in the repository.Can you tell me ?Thank you @sunset1995

Hi @glacierwl,

Maybe you can trace the original repo LayoutNet (I'm just simply downloaded the processed datas without processing myself).

Or you can tried my new project on layout estimation: HorizonNet.
For training/finetuning on your own dataset, simply put all image under data/your_datas/*.png and the corner positions on the equirectangular image under data/your_datas/*.txt.
All images should in the size of 512 x 1024 and below is an example of the corners txt:

123 115
123 378
426 141
426 353
680 180
680 318
824 175
824 323

where the first column is x positions and second column is y position on your image.

Actually,I have tested my dataset(panorama+corner position) using HorizonNet before. When I want to test them using LayoutNet, I get stuck in the puzzle about the conversion from corners txt to edge map and corner map. I have found some codes in the original repo,Thank you.@sunset1995

I have generated edge map and corner map from label.txt and panorama.Just revise some codes in this link.
