120m range 2.5kg HiSLAM LiDAR in integrated surveying and mapping
application of aboveground and underground space
In recent years, with the rapid development of China's economy and
the construction of smart cities, the development and utilization
of urban underground space has reached an unprecedented scale. The
construction of urban subway drives the large-scale development of
underground space, high-rise buildings promote the 3D development
of underground space, and the demand of comprehensive disaster
reduction drives the construction of underground space. In order to
strengthen the development, utilization and management of
underground space, the state and local governments have
successively formulated management measures, bringing the
development, utilization and management of underground space into
the legal track. The competent department has also formulated
special technical specifications for underground space mapping, so
as to provide a certain technical basis for obtaining the 2D and 3D
data of underground space. However, at present, the main
underground space mapping technology methods include: connection
measurement by control point introduction, digital mapping for
spatial 3D information acquisition and so on. These traditional
measurement methods have low efficiency and poor overall accuracy.
In the case of lack of GNSS signals and difficulty in positioning,
the emergence of SLAM laser scanning technology solves the problem
of integrated 3D spatial survey and mapping of aboveground and
underground space.
HiSLAM products are lightweight and portable. Based on 3D SLAM
algorithm, it can achieve the effect of GPS free operation. It is
suitable for data collecting of underground space surveying and
mapping in complex environment. It has the advantages of simple
operation, high efficiency, mobility and flexibility. Through a
series of operations such as data acquisition route planning,
control point and target setting, data acquisition, data processing
and 3D modeling, HiSLAM can establish a unified coordinate
reference aboveground and underground, so as to achieve the purpose
of integrated surveying and mapping.
Main features of HiSLAM LiDAR
