Engineering data compendium. Human perception and performance. User's guide
The concept underlying the Engineering Data Compendium was the product of a research and development program (Integrated Perceptual Information for Designers project) aimed at facilitating the application of basic research findings in human performance to the design and military crew systems. The principal objective was to develop a workable strategy for: (1) identifying and distilling information of potential value to system design from the existing research literature, and (2) presenting this technical information in a way that would aid its accessibility, interpretability, and applicability by systems designers. The present four volumes of the Engineering Data Compendium represent the first implementation of this strategy. This is the first volume, the User's Guide, containing a description of the program and instructions for its use
SalsaNet: Fast Road and Vehicle Segmentation in LiDAR Point Clouds for Autonomous Driving
In this paper, we introduce a deep encoder-decoder network, named SalsaNet,
for efficient semantic segmentation of 3D LiDAR point clouds. SalsaNet segments
the road, i.e. drivable free-space, and vehicles in the scene by employing the
Bird-Eye-View (BEV) image projection of the point cloud. To overcome the lack
of annotated point cloud data, in particular for the road segments, we
introduce an auto-labeling process which transfers automatically generated
labels from the camera to LiDAR. We also explore the role of imagelike
projection of LiDAR data in semantic segmentation by comparing BEV with
spherical-front-view projection and show that SalsaNet is projection-agnostic.
We perform quantitative and qualitative evaluations on the KITTI dataset, which
demonstrate that the proposed SalsaNet outperforms other state-of-the-art
semantic segmentation networks in terms of accuracy and computation time. Our
code and data are publicly available at
