5mm@50m accuracy and 1500m long range integrated UAV Mapping System
PM-1500 with 2 million points/s high frequency
PM-1500 UAV Mapping System, based on a new generation of core
technology framework, is a newly launched domestic airborne LiDAR
with high point frequency, high line frequency, high precision and
high integration. The core component of the system is the laser
scanner with multi-echo technology function which is independently
developed by Wuhan Hi-Cloud Technology Co.,Ltd. Integrated
high-precision laser scanner, high-precision POS (GPS, IMU) and
other sensors, supported by the time synchronization technology of
independent intellectual property rights and integrated
multi-sensor integration technology, it can synchronously obtain 3D
laser point cloud and POS data, quickly generate DSM, DEM and DOM
and produce DLG and 3D models through a complete set of data
processing and application software.
It can be applied to multi rotor UAV, VTOL fixed wing UAV, small
aircraft and helicopter to obtain dense high-precision laser point
cloud data on the ground on a fast flying mobile platform. It is
widely used in survey grade mapping, digital 3D
modeling,topographic surveying and mapping, cadastral survey,
traffic survey, power line inspection, forestry survey, disaster
monitoring and other fields.

Features of PM-1500
1. High precision: The ranging accuracy of PM-1500 UAV mapping system can reach
5mm@50m, and the comprehensive accuracy of the system is better
than 5cm, meeting various high-precision application scenarios.
2. Long range: The maxmum range can reach to 1500m@60%. The ultra
long ranging greatly ensures the operation safety in the
environment of large topographic fluctuation and enables the system
to carry a flight platform with higher flight altitude and faster
speed, set a wider flight belt, and collect more point cloud data
at the same time
3. High frequency: The frequency can reach to 2 million points per second. This high frequency makes the point
cloud data more refined and can more truly reflect the landform of
the survey area, rather than fitting the ground object coordinates.
In addition, high frequency LiDAR equipment can be equipped with
UAVs with faster cruising speed, which can improve the operation
efficiency.
4. Multi echo: The PM-1500 UAV mapping system can obtain up to 4
echo signals. The laser scanning sensor in the system emits laser
pulses to penetrate the vegetation gap and reach the ground, so as
to obtain the terrain information under the vegetation.
5. Integration: It highly integrates sensors such as laser scanner,
GPS, IMU and aerial survey camera, etc. It is suitable for multi
platforms such as VTOL fixed wing UAV, multi rotor UAV and
helicopter.
6. Lightweight: The overall weight of the system is less than
4.4kg.It can be easily carried by an individual, whether by plane
or high-speed rail.
7. Cost-effective: PM-1500 UAV mapping system is independently
developed by Hi-Cloud. It has the characteristics as long range,
high point frequency, high precision, stable overall performance,
fair and generous price and super cost-effective.
Practical project by PM-1500
Inspection of 500kV DC transmission line
Project overview: The inspected line of the project is 500kV DC
transmission line segment, including 3 base towers and 2 intervals,
with a total length of about 0.8km.The transmission line in this
section is electrified, with undulating terrain, vegetation
coverage, rich geomorphic types, good intervisibility between
towers, and roads can reach below the towers.
Project requirement: Danger point status analysis/Danger point
predictive analysis/Component status quantitative analysis
Solution: The PM-1500 UAV mapping system is used for data
acquisition. DSM/DEM will be quickly generated for DLG and 3D model
production.
