MORGAN HILL, CA – The mobile mapping market is poised for remarkable growth, thanks to breakthroughs in LiDAR technology, a host of new applications, and the economics of the business – so said Erich Smidt, European Sales Director for Velodyne LiDAR, during a keynote presentation at “Capturing Reality,” the 3D, Laser Scanning & LiDAR Technologies Forum.

The takeaway? According to Smidt, “implementations that can do more, across a greater number of market segments, for far less money.” Backing up that conclusion were a half-dozen companies and applications deploying Velodyne’s multi-channel, real-time 3D LiDAR sensors – the 32-channel HDL-32E and the lighter, more compact VLP-16 LiDAR Puck -- for various mapping applications.

Capturing Reality focused on the use of laser scanning, 3D imaging and LiDAR to support infrastructure development, BIM, transport, urban and coastal zone mapping, asset management, 3D visualization and GIS applications. More than 400 delegates from 35 countries gathered to hear 46 presentations delivered by leading experts. Attendees also visited the accompanying exhibition of more than 40 hardware/software manufacturers and service providers. In addition, a series of live demonstrations and technical workshops provided a very busy three-day schedule.

“Based on the product integrations at Capturing Reality, it’s clear that car-mounted mobile mapping via real-time 3D LiDAR sensors has come of age,” Smidt said. “Advancements in low-cost, real-time 3D LiDAR scanners on even more mobile platforms have expanded the market in a big way. We’re now seeing integrations that deploy sensors weighing less than a kilogram (830g) in UAV applications, including forest management, power line monitoring, and oil & gas change management. New 3D LiDAR integrations are enlisting multi-copters, fixed wing and small size gyro-copters. At the same time, multiple-channel scanning is proving remarkably effective under turbulent conditions and for minimizing shadows – what we often refer to as ‘looking around corners.’”

Among the hottest emerging areas within mobile mapping, according to Smidt, are implementations without GPS/IMU that use SLAM (simultaneous localization and mapping) algorithms, thereby reducing payload weight and extending flight times. These SLAM algorithms are especially important for indoor mobile mapping solutions, with sensors on backpacks and push carts creating 3D maps of interior real estate and other BIM applications within minutes after scanning.

Among the highlights of the Forum:

Routescene, based in the U.K., presented its LidarPod supporting both the HDL-32E and the VLP-16 as options in a highly compact, sleek, carbon-fiber design. Combined with Routescene’s LidarViewer, raw data can quickly be turned into usable GIS information. Routescene solutions are available in the automotive, marine, rail and UAV markets.

Topcon presented its second-generation mobile mapping solution, migrating from the IP-S2 with Velodyne’s HDL-64E to the much more compact IP-S3 using the HDL-32E. The IP-S3 obtains high-quality measurements with detailed shapes of objects based on 5MP 360° cameras and 700,000 data points per second from the HDL-32E. An instant preview of the acquired data is available immediately upon completion of a data collection session.

Backpack-based surveying. Velodyne’s compact VLP-16 LiDAR Puck was an integral part of systems on display by Microsoft and Leica Geosystems. Leica’s backpack sported two of Velodyne’s LiDAR Pucks in order to obtain almost full 360° coverage in horizontal and vertical directions, with remarkable point cloud density. Microsoft emphasized that its UltraCam Panther backpack solution sporting the lightweight VLP-16 can easily be integrated with software packages like Orbit GT (below), resulting in industry-leading workflows and maximum customer benefit.

Software provider Orbit GT showed its Everything Mobile Mapping™
portfolio, an end-to-end application that uses Velodyne LiDAR point cloud data to cover
production, extraction and sharing/publishing in an integrated and optimized workflow.

VIAMETRIS, which develops innovative technologies in mobile 3D scanning and automatic data recognition, presented an indoor mapping trolley system that can incorporate the VLP-16 in an outdoor implementation. VIAMETRIS previously worked on a development involving the Velodyne HDL-32E spread on a car’s roof. Using innovative 6DOF (Degrees of Freedom) SLAM, VIAMETRIS is among the earliest champions, and adopters, of the VLP-16. The company’s research team developed a backpack prototype based on a VLP-16 to manage positioning in indoor and outdoor environments. Because the VLP-16 is a 3D sensor, the positioning process is able to calculate a trajectory based on SLAM technology.
