Deep Learning-Based Framework for Feature Extraction

This paper by Wen et al., presents a deep learning-based framework for road marking extraction, classification and completion from three-dimensional (3D) mobile laser scanning (MLS) point clouds. Road markings play a critical role in road traffic safety and are one of the most important elements for guiding autonomous vehicles (AVs). High-Definition (HD) maps with accurate road marking information are very […]

Measuring Forests in 3D Provides Greater Accuracy

Measuring forests in the U.S. with 3D laser scanning indicates they may have significantly more carbon than previously thought. In a recent article by A.E.L. Stovall in Science Trends he reports that terrestrial laser scanning is providing more accurate estimates of tree biomass. A new method found 25% more carbon in trees than the traditional approach The good news is […]

Airborne Lidar – Discrete Return or Full Waveform?

image of plane collecting Airborne Lidar

This paper from 2011 provides an excellent treatment of the difference between discrete return airborne lidar and full waveform digital signal processing. Each has its strengths and weaknesses. Discrete return (DR) airborne lidar systems can record 4 returns Full waveform (FW) can record an unlimited number in theory Some systems provide both sensors DR is catching up to FW Excerpts […]

3D Laser Scanning Standards and Guidelines from Caltrans

logo of Caltrans Develops 3D Laser Scanning Standards

3D laser scanning standards and specifications for Caltrans applications were developed to promote large-scale deployment of this technology into Caltrans day-to-day survey operations. This report documents the AHMCT research project, “Creating Standards and Specifications for the Use of Laser Scanning in Caltrans Projects.” DOTs and private contractors have used laser scanning in highway survey applications and found that it reduces […]

Pavement Markings Auto-Extracted From Point Clouds

Article Highlights:  The use of Mobile Laser Scanning for collecting highway conditions such as pavement markings is increasing. Since pavement markings are made intentionally reflective their return intensity can be used to auto-extract them from the point cloud. Extracting them can be a challenge given the accuracies of current MLS systems (cm-level), relative to the thickness of the markings (mm-level). […]

Simon Ritchie, based in London is tracking the democratisation of Lidar Surveying, but his research shows that the pace is still slow, despite the emergence of the price crushing, autonomous vehicle market. Introduction Lidar has been used for land surveying for fifty years or more.  In days gone by the scanners were heavy and had to be carried by a […]

Frequency Scanning Interferometry For High Accuracy

Frequency scanning interferometry uses a tunable laser to provide highly accurate distance measurements. It was first developed by researchers at the University of Oxford who were working on the Large Hadron Collider at CERN. The system they have developed enables a single measurement device to simultaneously direct multiple laser beams to many targets, measuring each with extreme accuracy.   If you […]

Alluxa is a world leader in high-performance optical filters and thin-film coatings. In this highly informative white paper Alluxa explains how their high-performance, ultra-narrowband interference filters improve LIDAR signal-to-noise ratios. Arguably the most versatile active remote sensing technique, LIDAR (Light Detection and Ranging) is used across platforms and across disciplines. Long known to be one of the most important technologies […]

UAV LIDAR and the 400 ft FAA Ceiling Limitation

Photo of UAV Going Digital Requires Capturing a Digital Twin

When Jeff Fagerman, CEO and Founder of LiDARUSA provides his insights on an important topic like UAV lidar it is a good idea to take a few minutes to read what he has to say. Editor’s Note – This is one of the first documented examples of how the autonomous vehicle start-ups are putting pressure on the lidar manufacturers. It […]

Novel LiDAR Data Improves Our Understanding of Tropical Forests

Dr. Kim Calders and his team have just completed 2 months of field work in Australian tropical forests collecting both terrestrial and UAS lidar data to support a novel lidar data fusion methodology. Forest ecosystems contain more biomass than any other ecosystem. However, estimating biomass without cutting down trees is difficult. Traditional methods of estimating aboveground biomass (ABG) are based […]
