How to do inferencing for a given 3d point cloud of room ? about floornet HOT 7 OPEN

Please refer to https://github.com/art-programmer/FloorNet/blob/master/RecordWriterCustom.py for writing your own data as a tfrecords file. Then you can run inference similar as did in evaluate.py. You don't have to provide images. However, if you don't have images, maybe better to also train the model without images.

from floornet.

Hello!
Thanks for the reply. So I am actually trying to use the pre-trained model and want to do inferencing on my pointcloud datatset (2-3 pcd files). So what I understood is -

1. I will first convert my pointcloud dataset into tfrecords file.
2. Then I can run inference similar to evaluate.py ......right?

By images I meant while writing data into tfrecords file do I have to also provide images which is captured during scanning?

from floornet.

Yes, you are correct. If you have images, it should be better to provide. If not, you can leave zero values to the image_feature field.

Hi!

So I was trying to use the RecordWriterCustom.py file which you had pointed out earlier to convert custom point cloud scans to tfrecords file.

1. Initially I converted all my ".pcd" files to ".npy"
2. Kept the numChannels =3 as I am only giving XYZ points.
3. Run the RecordWriterCustome.py code which successfully converts (after some tweakings in the code) the point cloud scans to ".tfrecords" file . Initially I gave only one point cloud file.

Now when I am using this file to evaulate :

python train.py --task=evaluate --separateIconLoss after which I get the following error

Not able to understand what the exact problem is?
If you possible can point out what is exactly going wrong? or any pointers to resolve this problem.

Thanks

I am still not able to do prediction on my custom pointcloud data. A detailed insight on this will be greatly appreciated.

can u share RecordWriterCustome.py ?

Someone was able to solve this? I am getting the exact same problem
