LiDAR Point Cloud Compression by Vertically Placed Objects Based on Global Motion Prediction

open access: yesIEEE Access, 2022
A point cloud acquired through a Light Detection And Ranging (LiDAR) sensor can be illustrated as a continuous frame with a time axis. Since the frame-by-frame point cloud has a high correlation between frames, a higher compression efficiency can be ...

Learned Point Cloud Compression for Classification

open access: yes2023 IEEE 25th International Workshop on Multimedia Signal Processing (MMSP), 2023
Deep learning is increasingly being used to perform machine vision tasks such as classification, object detection, and segmentation on 3D point cloud data. However, deep learning inference is computationally expensive. The limited computational capabilities of end devices thus necessitate a codec for transmitting point cloud data over the network for ...

Cylindrical Coordinates for Lidar Point Cloud Compression [PDF]

open access: yes2021 IEEE International Conference on Image Processing (ICIP), 2021
We present an efficient voxelization method to encode the geometry and attributes of 3D point clouds obtained from autonomous vehicles. Due to the circular scanning trajectory of sensors, the geometry of LiDAR point clouds is inherently different from that of point clouds captured from RGBD cameras.

An Efficient LiDAR Point Cloud Map Coding Scheme Based on Segmentation and Frame-Inserting Network

open access: yesSensors, 2022
In this article, we present an efficient coding scheme for LiDAR point cloud maps. As a point cloud map consists of numerous single scans spliced together, by recording the time stamp and quaternion matrix of each scan during map building, we cast the ...
