System advantages of PM-1500
1. The overall structure of PM-1500 airborne laser measurement system has been innovatively optimized. It highly integrates sensors such as laser scanner, GPS, IMU and aerial survey camera, etc. It is lightweight and easy to install. It is suitable for multi platforms such as VTOL fixed wing UAV, multi rotor UAV and helicopter.
2. The overall weight of the system is less than 4.4kg. It can be easily carried by one person, whether by plane or high-speed rail. Even if you go out to work with UAVs and other accessories, an ordinary vehicle can load all of them, which is very convenient.
3. The ultra long ranging of 1500 meters greatly ensures the operation safety in the environment of large topographic fluctuation. At the same time, the ultra long ranging 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, which greatly improves the point cloud acquisition efficiency.
4. The super high frequency of up to 2 million points per second 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, and more data can be obtained in the same time.
5. High precision is the core demand in the field of surveying and mapping. The ranging accuracy of PM-1500 airborne laser measurement system can reach 5mm@50m, and the comprehensive accuracy of the system is better than 5cm, meeting various high-precision application scenarios.
6. PM-1500 airborne laser measurement system applies multi echo technology. 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. The 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.
7. PM-1500 is a new generation of high-precision airborne LiDAR flagship system 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.
Pracital application projects of PM-1500
1. 3D City Model Project
Overview: The total area of the survey area is about 10 square kilometers. It is necessary to obtain the original laser point cloud and oblique image in the survey area, and generate the 3D model according to the obtained original data.
Requirement: The laser point cloud obtained by airborne LiDAR aerial survey technology and the digital image data taken by oblique camera are used to generate Digital Elevation Model (DEM) and Digital Orthophoto Map (DOM) and produce terrain model. At the same time, the 3D model is generated based on laser point cloud data and line drawing.
Solution: The project adopts PM-1500 LiDAR carried by UAV for measurement. Take off and landing points shall be located with wide vision and high altitude as far as possible.
