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.
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 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.
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.

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...
This video gives you step-by-step instructions on mounting our Snoopy system to a vehicle. See www.lidarusa.com for more information! NOTE: The video says to "hand tighten" the screw on the mount, but if you feel it is absolutely necessary, you may use an allen wrench to tighten even further. Just make sure not to over tighten!

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.
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.

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.
