Each channel has an intrinsic angle offset, both horizontally and vertically. The offsetted angles are recorded in this lidar unit's angle correction
file. In case you need to obtain the file again:
· send PTC command 0x05, as described in Hesai TCP API Protocol (Chapter 5);
· or export the file using PandarView, see the PandarView user manual;
· or contact a sales representative or technical support engineer from Hesai.
The angle correction file lists the elevation and azimuth of each channel's outgoing beam, relative to the center of the exit pupil (shown as a
yellow dot in Figure 1.6).
