Polar coordinate system definition
For secondary development, G4 internally defines a polar coordinate system.
Pole: the center of the rotating core of the G4;
Positive direction: clockwise;
Zero angle: The zero angle is offset from the exit of the G6 PH2.0-5P interface line by 4°
counterclockwise (top view)
Due to individual differences, there is a +/- 3° deviation exists as shown below:
0°~360°

FIG4 YDLIDAR G4 POLAR COORDINATE SYSTEM DEFINITION
Note: When the Lidar is assembled on the machine, the deviation of the assembly may cause slight difference in
the consistency of the zero position. For the convenience of use, we provide zero calibration software, which can
customize the zero direction and assemble to the machine. The Lidar is calibrated twice. For details, please refer
to the instruction manual.
