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.

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.
To create an accurate 3D model of a movie sound stage, we use the Leica BLK360 LIDAR scanner. We then use that 3D model in Cinema 4D with Cine Designer to plan out the blocking, framing, and lighting for a white cyc shoot.

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.

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.
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.
http://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/f2017/cdg79/cdg79/cdg79/cdg79_finalproject_website.html The goal of this final project was to create a lidar 3d imaging system while on a limited budget. This is a system which takes many distance readings while pointing at many different angles. These distance readings are then converted into cartesian points and then plotted onto a graph. By plotting thousands of points, a three-dimensional image of the scene the system is pointed at is created.

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...
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...
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.
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.
