Lidars are depth measuring sensors widely used in autonomous driving and
augmented reality. However, the large volume of data produced by lidars can
lead to high costs in data storage and transmission. While lidar data can be
represented as two interchangeable representations: 3D point clouds and range
images, most previous work focus on compressing the generic 3D point clouds. In
this work, we show that directly compressing the range images can leverage the
lidar scanning pattern, compared to compressing the …
