GNSS – The Rest of the Picture

Matching the GNSS solution to the project continues to be an issue. In the previous article we looked at projects that were widely varying in requirements. First we reviewed the most general case requiring positioning to only a meter or more. Next we saw how an RTK system may be an appropriate solution for UAVs with the LOS restriction and […]

Where Are We With Feature Extraction?

Feature extraction and automated feature extraction were the main topics of discussion at conferences and during presentations about five years ago. Now, focal plane LiDAR and UAV’s are all the buzz. Feature extraction is still a vital part of what we do and are trying to do better. Where are we with feature extraction and how have we progressed? Companies […]

HERB Gets a New Eye

Background HERB 2.0, also known as the “robot butler”, is an ongoing project in the Personal Robotics Lab at Carnegie Mellon University (CMU). Velodyne’s Frank Bertini recently had the opportunity to visit CMU and experiment with integrating the VLP-16 Puck LiDAR sensor onto HERB’s head. David Butterworth, a graduate student at the CMU Robotics Institute, has been hypothesizing and testing […]

The Growth of Mobile LiDAR Mapping

Introduction The use of mobile LiDAR systems to map and document the condition of horizontal infrastructure, as well as the associated assets has moved out of the early adopter stage and it is now beginning to cross over into a much larger market. From its early days of being used to locate improvised explosive devices (IEDs) for the military in […]

Just How Accurate is Your Drone?

Unmanned Aircraft Systems (UAS) continue to influence the profession of remote sensing and mapping like few things ever have. Advances in computer technology, global positioning, and miniaturization have conspired to remove considerable barriers to entry. Many new practitioners are buying drones and providing these services and data for the first time. Much (not all) of the science and art of […]

The Zamani Project – Heritage Documentation Beyond the Point Cloud

The world’s tangible cultural heritage is suffering under an onslaught of war, cultural terrorism, vandalism, natural disasters, art theft, neglect and natural deterioration over time. While none of this destruction can be prevented by even the most advanced state-of-the-art digital documentation technology, digital heritage documentation makes a significant contribution to, at least, the virtual preservation of humankind’s past. It also […]

Selecting The Appropriate GNSS Solution

Determining the appropriate GNSS solution required in your mobile lidar system can be a bit troublesome. While this is true, it is only true if your preferred vendor offers a choice and if you are aware of the choices. Most manufacturers offer only a single solution, some offer only a particular brand, and others offer a variety. It is easier […]

Lidar System Accuracy

A client told me the other day that some vendors are promising vertical accuracy of LiDAR deliverables that exceed the LiDAR manufacturer specifications for that system and asked: Is it legitimate for a service provider to promise better accuracy than manufacturer specifications? Or, are service providers overselling their LiDAR services by promising high vertical accuracies? The short answer is “Yes”, […]

A Dithyramb on GNSS and Mobile LiDAR Mapping

by Jeff Fagerman, Lidar USA Location, location, location. For most businesses to succeed this is absolutely essential. While the business location is not nearly as important for mobile mapping as a restaurant or clothing store, location is very important for a mobile LiDAR system to be useful. It is not possible to generate a point cloud from a moving platform […]

Lidar Intensity Information: A Review of Applications and Processing Techniques

In addition to precise 3D coordinates most lidar systems also record “intensity”. To date, intensity data have proven beneficial in data registration, feature extraction, classification, surface analysis, and segmentation to name just a few examples. The list of applications also continues to grow rapidly, as lidar researchers and practitioners develop new and innovative uses of these data. The primary benefit […]

From Scanning Film to 3D Online Mapping

THE HISTORY This mapping story begins with a small company that was dominating the scanning market some 15 years ago, but it wasn’t the 3D laser scanning market – it was the scanning of large format aerial film. In those days digital cameras were just coming onto the scene and established aerial mapping companies were still looking to recover their […]

The Opportunity to Automate Quality Control

Author:  John M. Russo, AIA If you haven’t noticed there are a lot more people jumping into the laser scanning business lately.  Perhaps this is due to scanner prices dropping, or maybe it’s because the software is making it easier to process the data.  Maybe the growth of the market is just creating a lot of opportunity. Many of the […]
