JoLiDAR uses the latest laser mapping technology to allow users to collect accurate measure-level data using systems mounted on aircraft, drones, vehicles, ships and even backpacks. And our software can use real-time 3D color point cloud to view data in real time. Using JoLiDAR solutions to capture terrain, inspect utilities and construction sites, map disaster areas, and conduct urban development studies.
Multiple integration / carrying methods
The highly integrated high-precision 3D laser LiDAR system can be mounted on CW-30 VTOL fixed-wing UAV, manned helicopter, industrial-grade multi rotor, car, etc., which can be applied in powerline inspection, mapping, transportation, digital city and other application fields.
How does LiDAR work?
The technique we use to derive centimeter level precision is called Real Time Kinematic Global Navigation Satellite System (RTK GNSS). This system uses the satellite signal's carrier wave in addition to the information content of the signal and relies on a single GNSS reference station to provide real-time corrections. Now what happens during short periods of GNSS outages? Enter the Inertial Navigation System (INS): the INS uses a computer, motion sensors (accelerometers) and rotation sensors (gyroscopes) to continuously calculate the position, orientation, and velocity of the system. In order to combine the two systems, a very sophisticated algorithm, known as a linear quadratic estimation (LQE), operates on streams of noisy sensor data to produce a statistically optimal estimate of the system's position at any point in time. By fusing this information with the LiDAR data, a point-cloud is generated and visualized in real-time using Phoenix Aerial SpatialExplorer.
Compared to current ground scanning technology, JoLiDAR's solution enables you to scan areas faster and achieve higher precision results, whether on the ground or airborne.
