About the data visualization and instruction

Thank you for sharing!

After downloading the whole dataset, I find it difficult to utilize the dataset. I tried to open the bin file, but there were problems with the existing point cloud software and scripts. My understanding is to first merge bin files with the same prefix name. However, I still have trouble visualizing the point cloud. For example, the point cloud cannot be opened or the point clouds are all on the axis. I also have a problem with the use of provided images. There is no information about the dataset or guidance in the article.

I wonder if the author can provide a code for data processing or maybe a readme file on how to use the dataset. I want to use it as soon as possible.

I have also tried STcrowd from your group. It follows a similar file structure with HuCenLife. My code works fine in STcrowd. I want to know whether the original point cloud data from the .bin file has shape of (N,4) with (x,y,z,reflection) and ntype of float32.

Sorry for the leak of information. .bin file has shape of (N,5) with (x,y,z,reflection,t) and ntype of float32.
