Multi platform mapping system ARS-200 LiDAR with the high accuracy
of 15mm and the high frequency of 100000 points/s
ARS-200 mapping system is an airborne LiDAR which can be mounted on
multi platforms, such as multi rotor UAV, vehicle and backpack. It
is a Riegl LiDAR based system which developed and built by
Hi-Cloud. The whole integrated system is consisted of different
sensors such as high-precision laser, high-definition camera, GPS,
MEMS inertial navigation and storage control unit. With the time
synchronization technology of Hi-Cloud, the ARS-200 system
synchronously obtains 3D laser point cloud, POS data and image
data.
Main Features of the system:
i. It supports a variety of carrier platforms. According to
different industry directions and application scenarios, it can be
used with UAV, automobile and backpack.
ii. Each platform is equipped with corresponding rapid installation
structure design, which can realize screw free rapid installation,
greatly reduce the installation and deployment time on site, and a
single person can quickly install without any tools.
iii. The waterproof and dustproof grade of the system is better
than IP64. Under normal working environment, there is no dust entry
and moisture condensation in the body, and the equipment can
operate normally.
iv. The equipment is light and compact, with a weight of only
2.5kg. The lightweight equipment.
Based on the features and advantages, the ARS-200 UAV mapping
system can be widely used in emergency mapping, topographic
mapping, power line inspection, highway survey, coastal reef
survey, excavation and filling calculation, archaeological survey
and mapping and other fields.

Highway survey project of the system
The main line of the project is about 8km long. The survey area is
mainly mountainous terrain, with an average altitude of 600m. The
river crosses the survey area, and the altitude drop in some areas
is large. The vegetation in the survey area is lush, mostly
evergreen broad-leaved forest and low shrubs.
The main task of the project is airborne LiDAR survey and point
cloud processing of the certain section of the highway. The mean
square error of point cloud elevation is required to be less than
15 cm.
The traditional surveying and mapping operation is more dangerous
because of the traffic on the highway. It is difficult for GNSS
receiver to receive satellite signals due to dense vegetation and
large altitude drop in the survey area.
ARS-200 UAV mapping system is applied in this project. After
trajectory calculation, point cloud combine and other data
processing processes, the point cloud result is as follow:
