Optical Flow and Lidar Data Check

Lidar Data Check: Connect the drone to QGC Ground Control Station and click the corresponding icons as indicated by the arrows in the figure below.

Follow the steps below to find the current_distance data in MAVLink inspection. This data corresponds to the height measured by the lidar. Move the drone up and down to observe if the data changes correspond to the actual height.

Optical Flow Data Check: For optical flow data as shown below, select the data indicated by the arrow. Roll the drone left and right, and if the observed curve matches the following figure, it indicates correct optical flow data in X direction.

Select the data indicated by the arrow in the figure below. Pitch the drone forward and backward, and if the observed curve changes match the following figure, it indicates correct optical flow data in Y direction.
