vertices label format

[hosseinshirali]

Hi, thank you for sharing this project
I am trying to create a 3d bounding box on my pint cloud but I could not save it as vertices label format, can you help me how to do that?

Hi @hosseinshirali,

you can set the export format to vertices by changing the config.ini file. Simply change the line with the label format to:

LABEL_FORMAT = vertices

A graphical dialog for changing the settings is in development, currently all settings are set via the config. Simply change the parameters to your setup and restart labelCloud.

EDIT: There was a minor bug with the label export that I just fixed. So you need to pull the current version again.

The resulting label should look like this:

{
	"folder": "pointclouds",
	"filename": "exemplary.ply",
	"path": "pointclouds/exemplary.ply",
	"objects": [
		{
			"name": "cart",
			"vertices": [
				[
					0.05598266176063349,
					-0.2991399608786043,      # front right bottom
					0.18686448825820234
				],
				[
					-0.02056254376740252,
					0.24550747692925945,      # back right bottom
					0.18686448825820234
				],
				[
					-0.7632635953235803,
					0.14112765120921034,      # back left bottom
					0.18686448825820234
				],
				[
					-0.6867183897955443,
					-0.4035197865986534,      # front left bottom
					0.18686448825820234
				],
				[
					0.05598266176063349,
					-0.2991399608786043,      # front right top
					0.33686448825820237
				],
				[
					-0.02056254376740252,
					0.24550747692925945,      # back right top
					0.33686448825820237
				],
				[
					-0.6867183897955443,
					-0.4035197865986534,      # front left top
					0.33686448825820237
				],
				[
					-0.7632635953235803,
					0.14112765120921034,      # back left top
					0.33686448825820237
				]
			]
		}
	]
}

See the comments for the point location (I will probably change that to a more reasonable layout, like bbox with the next version!).

EDIT2: Vertices sequence has now been updated. See documentation.md.

Hope that answers your question!

Best regards,
Christoph

Hi @hosseinshirali,

I am sorry for the inconvenience. I forgot pushing the config.ini with the update.

Please clone again or simply add Z_ROTATION_ONLY = True in the [LABEL] section of your config.ini.

That should fix it.

yes it works great now, thanks for your help
