Traditional preprocessing steps, such as voxel meshing, masking, or vectorization, are usually applied for normalizing. Normalized point clouds, on the other hand, are still 3D modality data that will take a long time to process and cannot meet the real-time requirements of autonomous vehicles. ...
OSeg (Cen et al.,2022) introduces a novel strategy for open-world semantic segmentation of LiDAR Point Clouds. The proposed framework consists of two stages: (i) Open-Set semantic segmentation (OSeg) and (ii) Incremental Learning. For a fair comparison, we benchmark OSeg against our baselines...
Comparison of LiDAR, radar, and cameras. LiDAR’s smaller wavelengths make it able to create more precise and accurate distance maps, detecting smaller objects and greater detail. Radar’s longer wavelength range makes it less sensitive to changes in the medium through which it travels (such as...
This was used to perform three-dimensional imaging at up to 5 attenuation lengths for a range of 50 m and 4.5 attenuation lengths at 150 m. A comparison of light propagation through the oil-based vapour (i.e., artificial fog) was also made between short-wave infrared wavelengths and ...

The recent trend of fusing complementary data from LiDARs and cameras for more accurate perception has made the extrinsic calibration between the two senso
Multijunction vertical-cavity surface-emitting lasers (VCSELs) have gained popularity in automotive LiDARs, yet achieving a divergence of less than 16° (D86) is difficult for conventional extended cavity designs due to multiple-longitudinal-mode lasing.
