This video is an overview of the Phoenix Aerial AL3-16 LiDAR Mapping system. The AL3-16 can be mounted on any UAV that can lift 2.5kgs. In this video, a DJI S1000 is used and for the demonstration, we flew over an over an open pit. You can see how quickly we generate a dense pointcloud. You'll also see how LiDAR can pick up points underneath vegetation vs Photogrammetry will only map tree canopy.
This presentation discusses the characteristics of laser scanning. The focus is on the integration of scanners into both terrestrial and airborne LiDAR data collection systems. The presentation was created as part of a peer-reviewed educational series of Reusable Learning Objects (RLOs) on LiDAR.

Shafer Kline & Warren’s Light Detection and Ranging (LiDAR) scanning provides comprehensive, high-definition survey information with unsurpassed accuracy and efficiency. SKW’s LiDAR gurus Scott Confer and Patrick Crawford provide insight into LiDAR scanning, and how they leverage the technology to engineer solutions for energy and infrastructure. Many structures lack accurate as-built documentation or site data, and without this information, companies are unable to assess their current structures or perform facility modifications and updates. With scan speeds of up to one million points per second, LiDAR technology reduces the time needed to collect survey data and produce actionable data, which allows companies to complete projects sooner and meet tight deadlines. Additionally, LiDAR scan...
I finally found time to build a system to scan the LIDAR sensor from side to side using some 3d printed gears. This is meant to form the main obstacle avoidance system on my robotic platform. I am using a Garmin LIDAR Lite v3 sensor This is part of a series where I am looking to get my old robotic platform up and running again.

Mobile LiDAR scanning collection system coupled with automated data extraction can process up to 40 bridges per day. Accurate data on vertical clearances of roadway structures is critically important in oversize route planning. Horizontal clearance measurements must also be maintained. Traditionally collecting this data can be dangerous or can cause congestion with work crews subject to significant traffic hazards. Work must be performed during available traffic breaks which can induce errors. From a system-wide perspective clearance information in many cases is incomplete, inaccurate, difficult to maintain and difficult to access. Obtaining survey grade accuracy at traffic speeds is the proven, most efficient way to accurately measure various structures and roadway features.
Director of Remote Sensing Amar Nayegandhi explains the science and technology behind Light Detection and Ranging (LiDAR) services. Transcription: LiDAR can be considered an acronym for Light Detection and Ranging. It is a remote sensing technology that's used to measure distances, and it doesn't act on its own. It actually -- LIDAR typically includes three independently operating technologies. There's LiDAR, which is essentially a giant laser ranging device. The laser-ranging device sends out millions of pulses. Today, they can send out over 400,000 pulses in one second. That technology gives you the distance or the range to the target and there are two other technologies: GPS, which is Global Positioning System, or global navigations systems, that give you the location of the instrument...
This short video explains how a MEMS-based LiDAR works, from the LeddarCore integrated circuit to the optics configuration. Demoed for the first time at CES 2017 by LeddarTech, the solid-state scanning LiDAR is a high-resolution, long-range 3D solution for automotive applications (ADAS / autonomous driving).

The future of autonomous driving is on its way. The Velodyne LiDAR system consists of 4 HDL-32E LiDAR sensors mounted on the top of a car. This system is used to explore autonomous driving in a car. The lasers take 3-D measurements 20X's per second of the car's surroundings to generate 700k data points. The result is a real time image showing the surrounding environment.

The time-tagged laser scanner for cost-effective coastal, offshore and inland waterway surveying What if you could map the full marine environment in a single pass? Merlin is engineered specifically to integrate with your vessel's existing hydrographic surveying equipment. It enables you to synchronise Merlin's above-water lidar data with your below-water sensors to simultaneously produce an accurate dataset of the environment above and below the waterline. An affordable marine-grade lidar sensor Merlin gives you access to the advanced laser surveying technology you need without making you pay for equipment you already own.
No GPS? No Problem ! XacMaps is proud to announce the first ever mobile and aerial mapping solution free from the confines of satellite positioning systems. Interior and exterior scanning can be accomplished using a smarter, software apporoach to what has, in the past, relied on heavy and expensive GPS and other sensors such as inertial measurement units (IMU) to aid in stitching real-time LIDAR data. XactMaps is taking to the air with a fleet of unmanned aircraft capable of autonomous flight which will carry the LIDAR scanner into the future. From the ground up, scanning of entire buildings, fields, bridges and mountains, can be done in a fraction of the time and with very little manpower. Reducing cost and increasing efficiency are only the beginning of the benefits a versatile, n...
I finally add a servo to the lidar scanner to achieve up and down scanning. This is meant to form the main obstacle avoidance system on my robotic platform.

Engineering geologist, Pete Hobbs, explains how the British Geological Survey landslides team use Terrestrial Light Detection and Ranging (LiDAR). LiDAR is a land-based laser scanner which, combined with a highly accurate differential GPS and camera, enables us to produce 3D computer models of landslides in coastal areas.
A 3D Lidar Scan of the Lower Campus area of the Stevens Institute of Technology (SIT). The Scan was performed by a robotic ground vehicle named ROAMS (Remotely Operated and Autonomous Mapping System) developed by the Design and Manufacturing Institute (DMI) at Stevens Institute of Technology. http://www.dmi.stevens-tech.edu/
Encoders are a key part of vehicular LiDAR systems that are used to accurately map vast road infrastructure. Read the application note: www.renishaw.com/lidarapplication LiDAR scanning systems provide precise and accurate co-ordinate measurement data that is used to create realistic and detailed 3D city models viewable from street-level. LiDAR scanning systems consist of a laser range-finder with rotating scan mirror and various positioning and orientation systems. These systems capture 360° 3D point cloud data whilst rotating at more than 1000 RPM. Renishaw's ATOM™ encoder series is perfectly positioned to meet the challenges of high performance in a small footprint. The ATOM encoder is also the world's first miniature encoder to employ advanced filtering optics.
Zebedee is a handheld 3D mobile mapping system developed at CSIRO. The primary sensor is a 2D Hokuyo lidar scanner which measures the distances to surfaces in the environment (43200 samples per second). A simple spring mechanism is used to convert the natural motion of the operator into scanning sweeps that result in a 3D field of view. CSIRO's specialized software interprets the raw data to estimate the motion of the scanner and generate a 3D point cloud model of the environment. As seen in the video, the system is capable of large-scale mapping of a wide variety of environments ranging from built to natural scenes. Typically, the time it takes to map an environment is the time it takes to walk through it. For visualization purposes, the point clouds shown in this video contain only 9 p...
