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 http://amzn.to/2v7pGmt The slip ring to allow the sensor to rotate http://ebay.to/2eMPduk This is part of a series where I am looking to get my old robotic platform up and running again.

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.

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.
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...
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.
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.

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...
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.

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).

Simple 3D pointcloud generated with a mobile robot and a Hokuyo Lidar. The floating blob visible in the room is a quad rotor that was being tested at the same time.
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.
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...

With the use of a LiDAR scanner, LA County Public Works surveyors have drastically reduced time in measuring the boundaries of land. At Public Works, land surveyors play an integral role in designing and maintaining structures accurately and safely.
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...
