Request the dataset you are using

I wonder if you can provide the processed data set. When I use the PCN data set, there are multiple ply files with the same name, such as xxx_1.ply, xxx_2.ply, xxx_3.ply. If they are directly converted into pcd files, the SPM module still cannot read them. I also encountered many unsolvable difficulties when using House3K to generate data sets. So I wanted to ask you if you could provide us with the dataset you used

I have encountered this problem before. Maybe you need to use pcltools to convert the ply files to pcd files. For example, "pcl_ply2pcd input_file.ply output_file.pcd".

The problem I encountered when processing the house3k data set is that after processing the data set, the first dimension of many pillars is zero, which I cannot solve.

So can you provide a more detailed method of generating the data set or upload the house3k point cloud data set you used to the cloud disk? I would be very grateful if you could do this
