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 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.

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.
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.

The Lidar scanner or very similar versions are common components in other vacuum robots. Therefore they are well known and hackable! I am demonstrating that with a Raspberry Pi inside a Sunfounder RasPad demo unit which has some limitations ...
I put together a basic visualization tool in Processing to see what the data coming back from the rotating LIDAR scanner looks like.

This professionally produced HD video illustrates how laser scanners work and describes which scanner features are important to consider, the topic of "registration" or stitching multiple scans together, and what type of support is available for implementing the technology. Highlights of key Leica Geosystems' scanner features are described and a high-level overview of software is given.

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...

This is a LIDAR Lite v2 mounted on a DIY turnable disc running a Hector SLAM (Localization and Mapping) with it. The chassis can be 3D printed (more details here: http://grauonline.de/wordpress/?page_id=1233)
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.
