High freuency 2million points/s high accuracy 5mm@50m lightweight 4.4kg UAV LiDAR System PM-1500 with range 1500m

PM-1500 UAV LiDAR 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 laser scanner with multi echo technology is independently developed by Wuhan Hi-Cloud Technology Co.,Ltd. The whole system integrates modules such as high-precision inertial navigation module and aerial survey camera. With the innovatively optimized structure, the weight of PM-1500 UAV LiDAR system is only 4.4kg. PM-1500 can be mounted on different carriers, like multi rotor UAV, VTOL fixed wing UAV, small aircraft and helocopter.

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 is widely applied in different fields as basic surveying and mapping, digital 3D modeling,topographic surveying and mapping, cadastral survey, traffic survey, power line inspection, forestry survey, disaster monitoring and so on.

Specification of PM-1500

Features of PM-1500

• Long range: 1500m@60% reflecivity. 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.
• High prevcision: range accuracy=5mm@50m, system accuracy < 5cm. The accuracy can meet various high-precision application scenarios.
• High frequency: up to 2 million points per second. The point cloud data are more refined and can more truly reflect the landform of the survey area.
• Integration: the overall structure of PM-1500 UAV LiDAR system has been innovatively optimized. It highly integrates sensors such as laser scanner, GPS, IMU and aerial survey camera, etc.
• Lightweight: 4.4kg. It can be easily carried by an individual. It is suitable for multi platforms such as VTOL fixed wing UAV, multi rotor UAV and helicopter.
• Multi echo: 4 times echo. PM-1500 UAV LiDAR 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.
• Cost-effective: the high precision UAV LiDAR flagship system independently developed by Hi-Cloud. It's quite cost-effective and provides stable performance.

Application projects of PM-1500

1. 3D city model project: obtain the building height through the 3D model, obtain the building information through the oblique image and ground photos, and then build the building information database.

2. Topographic mapping project:

• The point density requirement is better than 16pt/m²;
• Horizontal/vertical accuracy requirements: ≤5cm, meet 1:500 topographic surveying and mapping requirement.

3. Inspection of 500kV DC transmission line project: 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.
