High frequency 2000kHz 1500m range 5mm@50m accuracy PM-1500 4.4kg
Airborne LiDAR System for building change detection
With the rapid acceleration of urban construction, it has also
brought many problems to urban planning and management , such as
the integration of urban and rural areas construction chaos, in
violation of the provisions of large-scale enclosure cover,
resulting in a large number of illegal buildings, destruction of
cultural relics, large-scale demolition and construction, and
irregular unauthorized approval, which seriously affect the
sustainable development of the city. Through the dynamic monitoring
of changes in urban buildings, we can comprehensively grasp the
planning implementation of urban buildings, compare the changes
with urban planning, assist urban management departments to timely
find and investigate and deal with various illegal buildings
according to law, and provide high-quality and intuitive spatial
information support for dealing with urban disasters and
emergencies. It provides a scientific basis for the government's
macroscopic decision-making and administration according to law.
PM-1500 airborne LiDAR mounted on Fenghu VTOL UAV or L150
multi-rotor UAV can give full play to its long-range advantages,
fly safely even over cities with high-rise buildings, and realize
multi temporal scanning of buildings in a large range of urban
scenes. Based on the point cloud data processing technology, the
differences of buildings in multiple time phases are automatically
compared, and the building change information is extracted, so as
to realize the automatic detection of building change.
