Error when using las2fmap.py about dbnet HOT 3 CLOSED

This is because down-sampled point clouds are not dense enough to be mapped into the 2D plane. In the paper, original point clouds which contain millions of points (like example.las) in each scene are used to generate feature maps directly to maintain enough information.

Sorry for late reply!
Got it! Thanks a lot!
By the way, would you like to share the code with using LSTM? I'm a noob of Tensorflow and want to learn how to do like your paper.

Thanks for the interest! For now, I have other projects to work on so maybe there is no time to add more models and results. There are also many fantastic tutorials of tensorflow (including LSTM ops) on Github, which are good materials to learn and start from :)

By the way, any pull-requests about new models/results are highly welcomed and appreciated!
