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.
Application fields of PM-1500 airborne LiDAR survey system
New basic surveying and mapping/Digital 3D Modeling/Topographic surveying and mapping/Cadastral survey/Traffic survey/Power line inspection/Forestry survey/Disaster monitoring/etc...
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.
