HD mapping with 3D LiDAR Laser Scanning | Urban & Town Area

Using a 3D LIDAR Laser Scanning for HD mapping the urban and town area, you can build maps that are more accurate and realistic, and it has become more and more mature.

Getting a better view of the land isn’t always easy, but it can be done with lidar HD mapping. This technology uses laser data collected from a LiDAR sensor to build a three-dimensional map of the surrounding area. These maps are the foundation of self-driving cars and urban and town planning, and many major companies use them to ensure their autonomous vehicles get where they’re going.

The most important thing to know about LiDAR is that it can generate very precise 3D cloud files that can be used to create topographic and geometric maps. They can also be used to create centimeter-accurate maps for in-vehicle localization.

Benifits to Use LiDAR for HD Mapping

Getting a better view of the land and streets isn’t always easy, but it can be done with lidar HD mapping. This technology uses laser data collected from a LiDAR sensor to build a three-dimensional map of the surrounding area. These maps are the foundation of self-driving cars, and many major companies use them to ensure their vehicles get where they’re going.

Using lidars to build centimeter-accurate HD maps is no small feat. You can use a lidar to create a centimeter- or inch-sized map of an entire city or to help you localize your AVs in the wild. These maps are typically vertically integrated with your AV software stack. The most advanced HD mapping technology combines lidars and cameras,, to create highly accurate maps of roads, streets, as well as some infrastructures around the roads, such as light poles, vegetations, road marks, buildings, powerlines, and traffic signs etc. 

A typical approach to creating the lidar HD map of an entire city involves assembling successive lidar scans into a large point cloud, then aligning them to produce a stacked map. While the process is not time-consuming anymore, thanks to LiDAR360 MLS with whole set of AI algorithm that can automate most of the post-process the LiDAR point cloud into vector objects. The end result can be a highly accurate map of an entire city. This can be used to help you with things like in-vehicle localization or augmented reality applications on mobile devices, as well as for the entire city planning or construction.

Our Solution for LiDAR HD Mapping

LiDAR Hardware Equipment for HD Mapping - LiBackpack and LiGrip

When the HD mapping project is small, for example only for few blocks , the handhelp and backpack LiDAR laser scanning system is sufficient. LiBackpack DGC50 and LiGrip are developed by GVI, and they are easy to operate, equiped with GNSS receiver that allows them to generate georeferenced 3D point cloud.

Mobile LiDAR Laser Scanners for HD Mapping

When it comes to large-scale LiDAR laser scanning for HD map creation, mobile LiDAR scanner is better option, because they can operate at higher speed to improve the efficiency and save the labour at the same time create high density 3D point cloud. 

HD Mapping LiDAR Point Cloud Data Analysis - LiDAR360 MLS

LiDAR360 MLS is a terrestrial mobile LiDAR laser scanning(MLS) point cloud feature extraction and analysis software independently developed by GreenValley International, which supports the processing and analysis of LiDAR point cloud and image data obtained by mainstream vehicle-mounted, backpack, or handled mobile mapping systems on the market.
Based on the leading artificial intelligence algorithm, the software performs massive point cloud data editing, 3D feature extraction and analysis, 3D vectorization of road elements, etc. It has the features of rich function, convenient operation, intelligent and efficient, friendly interaction, forming a complete processing chain of MLS point cloud data processing, high definition map and road asset survey.
The result data exported by the software can be directly imported into GIS, CAD, and simulation platforms, which can be widely used in high definition map production, facade survey, road asset survey and maintenance, etc. LiDAR360MLS accelerates information extraction with intelligence and depicts the real world with digitalization.
