4 times multi echo high precision 5mm@50m accuracy Airborne LiDAR
Survey system PM-1500 with long range of 1500m
PM-1500 airborne LiDAR survey system, based on a new generation of
core technology framework, is a newly launched airborne LiDAR with
high point frequency, high scan frequency, high precision and
tightly integration.The core component of the system is the laser
scanner with multi-echo technology function which is independently
developed by Hi-Cloud. It can be applied to multi rotor UAV, VTOL
fixed wing UAV, small aircraft and helicopter. It integrates
high-precision inertial navigation module and aerial survey camera,
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.

Main advantages of PM-1500 airborne LiDAR survey system
i. Integration: PM-1500 airborne LiDAR survey system highly
integrates sensors such as laser scanner, GPS, IMU and aerial
survey camera, etc. It is lightweight and easy to install, suitable
for multi platforms such as VTOL fixed wing UAV, multi rotor UAV
and helicopter.
ii. Lightweight: The overall weight of the PM-1500 airborne LiDAR
survey system is less than 4.4kg. Even if you go out to work with
UAVs and other accessories, an ordinary vehicle can load all of
them, which is very convenient.
iii. Long range: The ultra long ranging of 1500 meters of the
PM-1500 airborne LiDAR survey system greatly ensures the operation
safety in the environment of large topographic fluctuation, and
improves the point cloud acquisition efficiency.
iv. High frequency: The super high frequency of up to 2 million
points per second of the PM-1500 airborne LiDAR survey system makes
the point cloud data more refined and can truly reflect the
landform of the survey area.
v. High precision: The ranging accuracy of PM-1500 airborne LiDAR
survey system can reach 5mm@50m, and the comprehensive accuracy of
the system is better than 5cm, meeting various high-precision
application scenarios.
vi. Multi echo: The PM-1500 airborne LiDAR survey system can obtain
up to 4 echo signals, and can penetrate trees and feed back the
most real surface information even in densely vegetated areas.
vii. Cost-effective: PM-1500 airborne LiDAR survey system is a new
generation of high-precision airborne LiDAR flagship system
independently developed by Hi-Cloud. With its stable overall
performance, it is quite cost-effective.

Application project of PM-1500 airborne LiDAR survey system
Topographic Survey
The survey area is mainly flat terrain with small undulations and a
maximum height difference of 20 meters. There is a main road in the
survey area, with more vegetation and several densely populated
areas.
Accuracy requirement:
- The point density requirement is better than 16pt/m²;
- Horizontal/vertical accuracy requirements: ≤5cm, meet 1:500
topographic surveying and mapping requirement
Project difficulties:
- Complex terrain: The survey area has dense vegetation, and
traditional surveying and mapping cannot efficiently obtain
accurate elevation data in the survey area;
- Tight time: It takes 3 days to complete the data collection and
result data output of the survey area;
- Difficult transportation: The road conditions in the survey area
are complicated, and the transportation of traditional surveying
and mapping equipment is time-consuming and laborious;
- Epidemic: There are many residents in the village, and strict
closed-off control management during the epidemic brought certain
challenges to field data collection.
The main instruments and equipment invested in the project are the
PM-1500 airborne LiDAR survey system, L150 multi-rotor UAV
platform, Hi-Target IRTK2 receiver, and the urban off-road vehicle.
