The settings below apply to all drones.

 
Access: In the Home screen, select Grid Mission. In the Map view, tap ic_settings.png.
OPTION DESCRIPTION

Speed

Defines the drone's speed from a range between Slow and Fast (default). The maximum speed depends on the selected overlap and flight altitude. The scale has five levels corresponding to percentages of the maximum speed between 100% (Fast) and 50% (Slow). The speed should fluctuate between 2 and 8 m/s and is not constant during the flight since the drone slows down to trigger pictures.

 
Information: Reducing the speed might help to avoid capturing blurry images, but the Fast option is reliable for an optimal reconstruction with the software.

Angle (°)

Defines the tilt (not pan) of the camera between , horizontal, and 90° (default), vertical. The default value is vertical but if it was changed previously, the angle is the one of the last planned mission.

 
Information: The drone rotates regardless of the camera angle. It means the drone turns by 180° between two consecutive lines, which implies the heading of the drone is not constant. Therefore, the oblique images are not orientated in the same direction if the angle is tilted.

Overlap (%)

Defines the front overlap between 70%, 80%, and 90%. For more information about how to set the overlap: 202557459. The side overlap is computed such that the side distance between two images is twice the front distance meaning the distance between two images on the same flight line. The side overlap is adjusted with the number of lines so that it is close to the defined overlap value.

 
Tip: With the advanced mode activated, the scale is extended and more flexible (5% intervals). For more information about the advanced mode: 115001833743.

Face

Defines whether the drone should be oriented towards the center of the mission when taking pictures, Center, or not, Forward (default). The point of interest should the middle of the area to map.

 
Important: This option only makes a difference in terms of reconstruction if the camera is tilted. Indeed, it can for instance help to capture information from facades of objects.
