If I must need to retrain a model to reconstruct from custom point clouds?

[XiongjieYin]

Your research is excellent! I'm interested in your work. when I use your code to reconstruct a real-world building from point cloud,the code can construct cell complex.

[INFO] - cell complex constructed: 0.12 s
[INFO] - number of planes: 6
[INFO] - number of cells: 27

but a ERROR will arise as follows:

[INFO] - cut performed: 0.00 s
[INFO] - cut_value: 0.00
[INFO] - number of extracted cells: 0
[ERROR] - no reachable cells. aborting

Whether this error is caused by the fact that I used your helsinki_fullview model,and the model does not apply to my point clouds?
Do you have any advice for me to solve the problem?

Hi @Yin-xiongjie, the provided mini model is - as its name suggests - just for a quick demonstration. The rule of thumb is always to train your own model with your own data. That said, suppose you have a no-bottom point cloud, you could try to append bottom points to mimic a full-view input before using the mini model. This would nonetheless be non-optimal, but you might get reasonable results.

Thanks for your reply, I'll try your suggestion. Wish you a smooth work!
