High precision 5mm@50m range 1500m high frequency 2000kHz PM-1500
Airborne LiDAR Survey system for power line inspection
The traditional power line inspection mainly depends on manual
work, which is time-consuming and labor-consuming, and the
inspection line area is covered with dense vegetation, which can
not be accessed by personnel. In addition, the steep mountain
terrain also makes the inspection personnel in the inspection
process have certain personal safety risks.
PM-1500 LiDAR system mounted on Fenghu VTOL UAV or L150 multi-rotor
UAV can carry out intelligent acquisition of high-precision laser
point cloud data and image data in power line inspection process.
On one hand, based on the collected point cloud data, 3D real scene
modeling can be carried out which is convenient for managers to
view and browse the current situation of power lines. On the other
hand, through the automatic classification and processing of point
cloud data, according to the relevant regulations of power line
patrol, it can make real-time safety analysis, detect the fault of
dangerous points on the line, timely put forward early warning and
identify the specific location of dangerous points. The application
of PM-1500 LiDAR system in power line inspection not only solves
the problem of huge workload of line inspection, but also
effectively improves the efficiency and automation of line
inspection.
