- LiDAR point cloud segmentation is important for autonomous driving.
- We propose a CNN based model with high accuracy and real-time inference speed.
- Real-world data and simulated data are combined to train the model.
- Source code is released: https://github.com/BichenWuUCB/SqueezeSeg
3.Sampled-Point Network for Classification of Deformed Building Element Point Clouds
- Recognizing deformed objects is critical for disaster relief robots
- A deep learning method is proposed to classify deformed building elements from point clouds
- Synthetic deformations such as noise, bending, and truncation were applied to a CAD model database
- Robustness was achieved using improved regularization such as point sorting and resampling
4.GemSketch: Interactive Image-Guided Geometry Extraction from Point Clouds
- Interactive sketching for extracting geometries from point clouds
- Objects represented as generalized cylinders and cuboids
- Accurate within 5.66% Hausdorff distance for BigBIRD ground truth.
- Geometries produced used for object manipulation in clutter
5.Signature of Topologically Persistent Points for 3D Point Cloud Description
- We present the Signature of Topologically Persistent Points (STPP), a global descriptor for 3D point cloud data
- STPP uses persistent homology to encode a topological signature based on the birth-death pairing of the homology generators
- STPP can be computed quickly and efficiently, requires no preprocessing of the data, uses a single tuning parameter, and is competitive with state of the art global descriptors
6.AA-ICP: Iterative Closest Point with Anderson Acceleration
- We propose to apply Anderson acceleration (AA) for ICP instead of the commonly used Picard iteration procedure: xi+1 = ICP(xi)
- AA uses history of previous iterations to find a better guess for the next iteration
- AA-ICP was implemented as a part of Point Cloud Library (PCL)
- On real-world data AA-ICP converges significantly faster (up to 30-40%) compared to the unmodified ICP
- Novel 4D convolutional neural network architecture using descriptor values as input
- High robustness to noise and occlusion for realistic indoor point cloud data
- Superior performance for retrieval and classification on ScanNet and Stanford datasets

8.Real-Time Object Tracking in Sparse Point Clouds Based on 3D Interpolation
- New methods even to track sparse point cloud objects in real time is proposed.
- Proposed 3D interpolation for distributions, called EVD, augments information at unoccupied areas of target object.
- Through a coarse-to-fine grid search for real-time processing, the tracker find the optimal difference
9.Robust Generalized Point Cloud Registration Using Hybrid Mixture Model
- A novel point cloud registration method is proposed where the orientation information associated with each point is utilized.
- In the M-step of the algorithm, a closed-form solution to the scalar weighted rigid registration problem is proposed.
- The experiments demonstrate the proposed algorithm outperforms the other two under conditions of various noise levels, outliers percentages.
10.A General Framework for Flexible Multi-Cue Photometric Point Cloud Registration
- Register point clouds with no explicit correspondences
- We currently use intensity, range and normals for registration
- Easy to extend for using other cues
- Runs at framerate on TUM and KITTI data
11.Spatiotemporal Learning of Dynamic Gestures from 3D Point Cloud Data
- We demonstrate an end-to-end spatiotemporal gesture learning approach for 3D point cloud data using a new gestures dataset of point clouds acquired from a 3D sensor
- Nine classes of gestures were learned from gestures sample data through a 3D convolutional neural network that learns the spatiotemporal features in the data without explicit modeling of gesture dynamics.
- The developed model is able to classify gestures from the dataset with 84.44% accuracy.
