parameter adjustment, data collection, and downloading functions of the system;
(5) The power supply system is used to supply power to the system.
1.3 System Principles
The inertial measurement unit
（
IMU
）
obtains the position and attitude that meet the
accuracy requirements and accurately transmits it to the laser scanner, which is a high-
speed rotating laser scanner.
According to the range information and the rotation angle, the coordinates of each laser
point are quickly calculated, stored in the storage control unit.
