Mobile LIDAR Systems and Services Guide
Mobile light detection and ranging (LiDAR) systems represent a new level of automation and accuracy for surveying roads, including route inventory, bridge structures, bridge clearance and highway-pavement surveys. Vehicle-mounted laser scanner systems have significant advantages over traditional mapping methods, including improved safety for surveyors, faster survey speed and a minimal impact on traffic flow. This brief guide includes some of the mobile LiDAR sensors, systems and services on the market. Product descriptions were provided by the vendors.
SENSORS
These companies provide laser scanners that are integrated into mobile LiDAR systems and platforms.
Faro
Focus3D
Faro touts its Focus3D X 330 laser scanner as the smallest and lightest on the market. The scanner offers a long-range (330 meters) sensor, an integrated Global Positioning System receiver and the ability to scan even in bright sunlight. The company doesn’t offer a mobile mapping option, but others have adapted the Focus3D X 330 and other Faro scanners for mobile applications.
iXBlue

ATLANS-C is a high-performance position and orientation solution for air and land mapping applications. With its integrated INS-GNSS smart coupling technique, small size, light weight, low power consumption and robust design, ITAR-free ATLANS-C provides all the necessary data for demanding aerial survey and land mobile mapping applications.
Pavemetrics
Laser Crack Measurement System, Laser Road Imaging System and Laser Rut Measurement System
Pavemetrics sensors help infrastructure managers optimize their maintenance strategies and budgets as well as improve asset performance and safety through fast, accurate and automatic condition evaluation of transportation infrastructure. The company’s automated inspection technology is designed for daytime and night-time operation, with sensors producing high-resolution 2-D images and 3-D profiles of transportation infrastructure.
Phoenix Scientific Inc. (PSI)
Pavement Profile Scanner
PSI’s primary product, the Pavement Profile Scanner, is a polygon scanner with six sides used to point the LiDAR measurement beam at points along a straight line on the pavement, thereby scanning a line and generating the profile along the line six times per revolution of the polygon. Operating at 10,000 rotations per minute, the system generates 1,000 scans per second. With the scanner mounted seven feet above the pavement, the ±45-degree field of view produces a profile 14 feet long (twice the height).
Velodyne
VLP-16 LiDAR Puck
Velodyne recently announced the VLP-16 (also known as the LiDAR Puck), a 16-channel real-time LiDAR sensor costing only $7,999 and weighing in at a scant 600 grams. This makes it substantially smaller and significantly less expensive than previous-generation sensors.
HDL-64E
With its full 360-degree horizontal field of view by 26.8-degree vertical field of view, 5-15 Hz user-selectable frame rate and more than 1.3 million points per second output rate, Velodyne’s HDL-64E provides dense point clouds. The HDL-64E’s patented one-piece design uses 64 fixed-mounted lasers to measure the surrounding environment, each mechanically mounted to a specific vertical angle, with the entire unit spinning.
HDL-32E
Velodyne’s HDL-32E LiDAR sensor is small, lightweight, ruggedly built and features up to 32 lasers across a 40-degree vertical field of view. The HDL-32E measures only 5.7 inches high x 3.4 inches wide and weighs less than two kilograms. The HDL-32E generates a point cloud of 700,000 points per second with a range of 70 meters and typical accuracy of +/- 2 centimeters.
Z+F USA
5010-C
The integrated camera in the Z+F IMAGER 5010-C combines high-resolution color imagery with high-resolution scan data.
