This NEON Science video overviews what lidar or light detection and ranging is, how it works and what types of information it can provide. The video was produced by the National Ecological Observatory Network - a non profit project devoted to open science and open data.

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.

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.
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.

With the Neato XV-11 LIDAR Laser Range scanner connected to the STM32F429 DISCOVERY board we've made a handheld and wireless laser scanner for measuring distances. The 360-degree distance measurements is both shown on the LCD display and wirelessly (Bluetooth) sent to a PC for display using MATLAB. Furthermore the Touch display can be used to select two points and measure the distance between them, therefor using the handheld system to measure a room quite accurately.

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.
A mobile LiDAR scanner mounted on a car or an airborne scanner operated in a helicopter can provide a dense point cloud depicting highways, their surroundings and the road surface very accurately. Using photographs taken at the same time and control points measured with GPS improves the accuracy and helps to compensate the gaps in the GPS signal caused by tall buildings and trees. Laser scanning can be executed without putting people at risk in the middle of busy traffic.
This video documents one of the first projects to fly a LiDAR scanning system on an Unmanned Aerial System (UAS). The success of this project paved the way for an explosion in the applications for drone technology. The piece was directed, shot and edited by Chris McMurtry
The Power of Integrated Capability - Less than 5cm accuracy demonstrated - Peaceful Valley - CO, USA YellowScan develops tools for UAV Mapping. With our latest system, the Surveyor adapted for UAV surveying, you can gather in a few minutes a 3D image of your area, with a precision as high as 5 cm. In this video, YellowScan applications engineer explains how to produce your georeferenced point cloud from your Surveyor LiDAR Scanning system. He also demonstrates the accuracy of the YellowScan UAV payload for aerial surveying. The software used to visualize the point cloud is an open-source software called CloudCompare. After a decade of research and development, Pulse Aerospace is leading the charge in ushering a new age of unmanned aircraft systems. The Vapor combines the world’s most a...
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. This is part of a series where I am looking to get my old robotic platform up and running again.

my first foray into controlling an electromechanical actuator with a microcontroller, i built this with 2 specific applications in mind; first, as a potential laser harp system, and second as a primitive object detection system for an autonomous robot i'm building. it is currently programmed to move the servo to 7 different angles, each 8 degrees from the next, pausing each time for 150 milliseconds to give the servo adequate time to find the new position. with these long pauses, it takes a little over 1 second to perform a complete scan. it appears as though 150 milliseconds is more than adequate time for the servo to move 8 degrees (based on the stability of the laser impact points), but that a little more time may be warranted for the retrace sweep (the first laser point exhibits a l...
