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.

Hi-Cloud -- the leader of 3D laser scanning technology

Wuhan Hi-Cloud Technology Co.,Ltd. founded in 2012, and is a holding company of Guangzhou Hi-Target Satellite Navigation Technology Co.,Ltd (stock code: 300177) with more than 200 team members and a product service network covering the whole country.

Hi-Cloud has been committed to the development, application service and industrialization of high-precision 3D laser series products for long term. It has taken the lead in overcoming the key core technology of full waveform LiDAR, breaking the long-term monopoly of foreign technology. It has formed a full series of product line layout of 3D laser "sea, land and air", and is far ahead in the application field of high-precision of domestic equipment. It is one of the few 3D laser solution providers in China that fully master the core technology of LiDAR and realize industrialization. Products and technologies are widely used in geographic information surveying and mapping , digital city, industrial digitization and other fields to provide technical support for the construction and application of digital 3D world.

Hi-Cloud has applied for and owned 105 patents, 48 software copyrights, won a number of provincial and ministerial scientific and technological progress awards, won the title of "Gazelle Enterprise" in Wuhan East Lake Hi-Tech District for six consecutive years, and has been successively rated as a “High-Tech Enterprise”, Hubei enterprise technology center, an "Invisible Champion" in market segments, and "Little Giant" enterprise in Hubei Province.

In the future, Hi-Cloud will always adhere to the localization of high-end equipment as its own responsibility, and continue to promote the industrialization of domestic high-precision LiDAR, committed to become a global leader of 3Dlaser scanning technology.
