Lidar Structure
64 pairs of laser emitters and receivers are attached to a motor that rotates horizontally.
Figure 1.2 Partial Cross-Sectional Diagram
Figure 1.3 Coordinate System (Isometric View)
Figure 1.4 Rotation Direction (Top View)
The lidar's coordinate system is illustrated in Figure 1.3. Z-axis is the axis of rotation.
The origin is shown as a red dot in Figure 1.6 on the next page. All measurements are relative to the origin.
Lidar azimuthal position is defined in Figure 1.4. Y-axis corresponds to 0°.
Each laser channel has an intrinsic azimuth offset. Channel 18 is selected to define the lidar's azimuthal position.
For example, when Channel 18 passes the 90° position:
the lidar is at the 90° position;
the Azimuth field in the corresponding data block in the Point Cloud Data Packet will be 90°.
