Question about data

[xiankun1995]

Hello. I can run the train mode and test mode with the lmdb files you gave in segmentation task.
But the program will stop running when I use my files.
My files is obj format, and I convert it to lmdb format. Then I start train mode but program stop running.
If the data have special requirements in segmentation task?
Please give me some suggestion. Thank you!

The input of O-CNN is octree files, not obj files. For more details about the data preparation, please read our readme.

I'm sorry I didn't say it clearly.
I first run the tool octree.exe convert my obj files to octree files, and run convert_octree_data.exe convert this octree files into a lmdb. Last I run the train mode with the lmdb but the program stop running for a little while.

I can run your lmdb and get the train result. But I fail with my lmdb.

I could not give you an answer just according to your description.
I think you can compare the data that we provided (especially the points file we uploaded) and your data, then you should be able to find the reason.

Hello, now I know my data are differents with yours.
In your readme, I find there are three parts in your POINTS file: 1.dense points 2.normal information 3.correct part annotation. virtualscanner.exe can help me with part 1 and 2.
I download the original part annotation data by your link, and I see label and points are separate.
What should I do to input label information into POINTS file for completing part 3. Is there a function to read label information in VirtualScanner.cpp or other files?
Thanks!

Please refer to the function load_pointcloud defined in Line 142 of the .\octree\Octree\main.cpp.

The function load_pointcloud can load these *.points information to octree files. I can get the octree files with the segmentation label.
After I download "A Scalable Active Framework for Region Annotation in 3D Shape Collections", I see points and points_label are separate. What should I do to combine that two types of files and get *.points with segmentation labels like those *.points in your link?
Thanks a lot!
