Features of UAV Mapping System ARS-1000L
1. The system integrates the 3D laser scanner, POS module and fan
into the hardware architecture, which not only enhances the overall
performance and stability of the system, but also compresses the
volume to the extreme, and the overall weight is less than 4.5kg.
2. The small volume and weight of the system enable it to be well
carried on various carrier platforms. It is not only suitable for
mainstream multi rotor UAV and VTOL fixed wing UAV, but also can be
mounted on vehicle and backpack platforms for operation. Whether in
airborne, vehicle or backpack mode, the system is equipped with
corresponding installation firmware to meet the rapid installation
and deployment on the operation site.
3. The whole system adopts the fast sliding structure design, and
there is no gap between the rack and the system, which ensures the
stability and reliability of the equipment. There is no need for
screws during installation, which improves the on-site deployment
time. In addition, the system also provides a proprietary
lightweight anti-collision protective sleeve to provide certain
physical protection for the equipment and reduce unnecessary damage
to the equipment in some harsh environments and emergencies.
Further more, the loss prevention module is optional. After the UAV
is lost, the equipment position can also be found to facilitate the
search of equipment.
4. The maximum range of LiDAR system is 1350m, and the system can
operate normally even in the environment with large terrain drop.
Long range measurement can also improve the acquisition efficiency
of the equipment and collect more point cloud data in the same
time.
5. The laser emission frequency of the system is 750000 points per
second. A higher point frequency means that it can better reflect
the landform in the survey area and obtain more fine point cloud
data. In addition, high frequency LiDAR equipment can be equipped
with UAV with faster cruising speed. In the same time, more data
can be obtained, which improves the data acquisition efficiency.
6. The absolute accuracy of the system is better than 5cm, which
meets the needs of most application scenarios. Under the measuring
range of 150m, the ranging accuracy is better than 15mm.
Practical application project of UAV Mapping System ARS-1000L
Wind farm survey in mountain area
Overview
The survey area is mainly mountainous terrain. The average
elevation in the wind farm survey area is high, and the altitude
drop in some areas of the measurement area is over 300 meters. The
whole wind farm covers an area of about 12 square kilometers. The
vegetation is subtropical evergreen broad-leaved forest, with large
vegetation coverage rate and various types.
Difficulties
The terrain of the survey area is complex, the altitude difference
is large, the traffic is inconvenient, the climate environment is
bad. There are several wind turbines with a height of more than 100
meters in the survey area, so it is difficult to design the route.
The line of sight is blocked seriously, and it is difficult to
locate the take-off point.
Solution
The project adopts ARS-1000L airborne laser measurement system.
Three takeoff and landing points are selected in the whole survey
area for a total of seven sorties.
