3.1.4.1. Flight Safety
Control the aircraft takeoff and keep the flight within a visual line of sight. Fly the aircraft below
120 m (400 ft). Any flight altitude higher than that may violate local laws and regulations. Make
sure you understand and comply with the local laws and regulations before flying. Make sure to
read the Safety Guidelines before flight to ensure the safe use of the product.
3.1.4.2. Parameter Settings
On the camera view, switch the camera mode to Record Point Cloud.
Figure: Enable point cloud recording
For manual flights, select the non-repetitive scanning mode and the triple return mode, enable
RGB Coloring. Make sure that the network RTK is properly connected or an RTK base station has
been set up.
The RGB coloring feature controls whether the visible-light camera takes photos during LiDAR
point cloud data collection. We recommend that you keep RGB coloring enabled except in
nighttime operations.
3.1.4.3. IMU Calibration
Manual IMU Calibration: To ensure consistent inertial navigation accuracy, IMU calibration is
required before and after data collection and after 200 seconds of flight at a consistent speed. Fly
the aircraft to an appropriate altitude, switch to the camera view, and then click the Calibrate
button. A calibration area (a 30 m route) appears. The aircraft automatically flies back and forth
along the route for three times, finally stopping at the start point. (Ensure that no obstacle exists
along the 30 m route and the obstacle avoidance system is turned on.)
