A pulsed laser is used in the distant sensing technique known as LiDAR, which stands for Light Detection and Ranging, to measure ranges (varying distances) to the Earth. These light pulses produce precise, three-dimensional information on the shape of the Earth and its surface features when paired with other data captured by the aerial system. A LiDAR device’s main components are a laser, a scanner, and an advanced GPS receiver. The most popular platforms for gathering LiDAR data over large areas are aircraft and helicopters. Topographic and bathymetric LiDAR are two different types. While bathymetric LiDAR also measures elevations of the seafloor and riverbeds using water-penetrating green light, topographic LiDAR typically maps the land using a near-infrared laser. For data collection, a drone or a helicopter equipped with airborne LiDAR is used. As soon as it is turned on, Airborne LiDAR sends light toward the ground, and when that light strikes an item, it immediately bounces back to the sensor, providing an accurate distance measurement. The two types of airborne LiDAR are Topological LiDAR and Bathymetric LiDAR.
Major factors driving the growth of the market
Demand for Lidar drones is constantly increasing. UAVs frequently carry visible-wavelength video cameras, as well as sometimes long-wavelength IR cameras. However, it can be challenging to find dangers using these imaging techniques if they are concealed in the background, in the shadows, or behind a window that blocks out such wavelengths. To improve the likelihood of completely surveying these kinds of landscapes, active 3D imaging techniques can be applied. Additionally, the 3D data can be used to aid in the detection of dangers and obstructions (such as masts and cables) in low-light situations.
Trends influencing the growth of the market
The main drivers of the increase in demand for airborne LiDAR for military applications include the requirement for unmanned aerial vehicles to reduce casualties in combat, high precision LiDAR-based monitoring, protection of perimeters, and continuous aerial surveillance of areas.
System integration, the creation of 3D data processing methods, the combination of 3D data with information from visual and thermal cameras, and experimentation. Commercial off-the-shelf UAVs, allows quick deployment and get high-resolution data. A manned airborne sensor system often costs substantially more than UAV systems. Multi-rotor UAVs also have the benefit of being able to hover in one place if a particularly high-density data point is required.
The increase in defense spending will encourage procurement of airborne LiDAR systems and related systems to step up their production volumes and improve their quality, thereby enhancing competition in the global markets. Procurement will also be driven by prevailing geo political conditions in Europe and the Asia Pacific and increasing use of submarines for surveillance and intelligence gathering.
YellowScan, one of the top manufacturers of UAV lidar, unveiled Explorer, a new flagship long-range lidar system, at the commercial UAV Americans expo. Less than a year later, they released Voyager, their newest product, adding to their lineup of lidar systems. The long-range lidar technology can effectively cover intricate and vertical targets and is compatible with both human and unmanned aircraft. The Voyager can fly up to 440 meters above ground level (AGL), which is over 100 meters higher than the Explorer variant. It weighs only 3.5 kilos, not including the weight of the battery, and boasts a system precision of 0.5 centimeters and a system accuracy of one centimeter. The best users of YellowScan’s newest product are those entrusted with surveying some of the most difficult terrains, particularly those with dense vegetation. Additionally, it can function in a variety of temperatures between -10 and 40 degrees Celsius (14 to 104 degrees Fahrenheit). The scanner, which may be integrated with manned aircraft, multirotor UAVs, and fixed-wing UAVs, has a variety of possible users.
The AlphaAir 1400 (AA1400) and AlphaAir 2400 (AA2400) Lidar systems have been made available via HC Navigation (CHCNAV). Both options are lightweight airborne laser scanners that can be quickly and simply mounted on a variety of UAV platforms, as well as on small survey planes and helicopters. They are perfectly suited to high-density point corridor mapping applications, whether it is day or night, leaf-on or leaf-off, or whether there is a lot of vegetation present. For the AlphaAir, CHCNAV offers a number of external camera accessories. For data acquisition, users can select from 42, 100, or 150MP fully calibrated sensors. Additionally, setups can include Sony or Phase One nadir or nadir and oblique cameras. More applications that aim to boost the client’s return on investment can be helped by collecting high-resolution georeferenced and oblique imagery.
