48
meters horizontally away from the fore and aft towers (on the farther side of the operational segment)
to ensure adequate collection of point cloud data at the fore and aft towers and adequate distance
for IMU calibration (IMU calibration requires a distance of at least 30 meters, so the distance
between the first and the second waypoints and between the last and the second to last waypoints
should be at least 30 meters).
Figure: Adding a route at the fore and aft towers
1.
Flight Route Settings (Global):
Ø Speed: Speed is inversely proportional to point cloud density. We recommended that you
set Speed to about 15 m/s to ensure both efficiency and effectiveness.
Ø Altitude: Use the default value and do not modify it.
Ø Aircraft Yaw: Set it to Along Route.
Ø Gimbal Control: Set it to Manual Control by RC. Adjust the gimbal pitch angle based on
the task type.
Ø Waypoint Type: Set it to Straight route. Aircraft stops.
Ø IMU Calibration: Turn it on.
Ø Power Saving Mode: Turn it off.
Ø Finish Action: We recommend that you set it to Return To Home.
Figure: After IMU Calibration is enabled, Zenmuse L2 automatically calibrates the inertial
navigation system based on the route, without the need for operators' intervention
2.
Waypoint Settings:
First waypoint: Start executing Zenmuse L2's data collection task. Add Gimbal Pitch Rotation(°) as
the first action at the waypoint and set the pitch angle to -75°. Then, add Start point cloud modeling
recording as the second action.
