The Panorama mission lets you take a set of photos that can later be stitched together to form a horizontal Panorama. There are three steps involved in creating a Panorama mission
  1. Basic mission objectives (eg. speed)
  2. Mission location and panorama arc
  3. Panorama vertical steps - you can take multiple panoramas stacked up at fixed altitudes, useful for view assessments from multi-storey buildings.
NOTE: If you have a Spark you cannot use this mission. The Spark does not support waypoint missions.

After flight, it is even possible to produce a simple stitched panorama on the tablet to check the result before you leave site.

To create a Panorama mission, navigate to the Plan screen using the main menu as shown below. Tap the "Hamburger" icon at the top left of the screen to display this menu:

Image

On the Plan screen, move the map close to the area that you would like to survey and zoom in to a comfortable level. Don't zoom in too far. While you can zoom and scroll later, it is easier to move the map to roughly where you need it first.

When ready to create the mission, press the round blue + button at the bottom right of the screen to reveal the mission selector. Tap on the "Panorama" item and press Next to start building a Panorama mission.

Step 1: Mission Objectives

The first step of any mission is the Mission Objectives dialog. This dialog allows you to choose basic settings for the mission and the items on it will adapt to suit the mission type. This will slide in from the right of the screen.

Note that you can exit mission creation by tapping the X at the top left of the objectives dialog. This will cancel new mission creation and retain whatever mission is currently loaded.

Image

In the example above, there are several important settings that you can change, but in many cases the defaults will be suitable
  • Camera - The camera should show the drone that you are connected to now, or were last connected to.
    • Tap on this section of the dialog to display the camera settings.
    • Here you can change to RAW image types, set white balance, choose video mode and more.
Tip: You don't have to change Camera settings now, you can change them at any time prior to takeoff. Camera settings are available from the main app menu
  • Min Safe Alt - this is a critical setting for the entire mission.
    • Whatever other settings you choose, no part of the mission can be lower than this altitude.
    • It also defines the altitude at which the vertical part of takeoff finishes and the vertical part of landing begins
    • Make sure the Min Safe Alt is set well above any obstacles such as tall trees or buildings in your area of operations. The safety of the drone and people and property around you is your responsibility.
    • Remember - all altitudes are measured relative to the Home point.
  • Sidelap % - Since most of the mission involves the drone rotating around a central point, the sidelap % defines the approximate sideways overlap of each photo with the one before it.
    • The higher this value, the more photos will be taken, but the slower the mission will be as the drone must pause for each photo. This can vary from 40% to 95%.
Tip: Photos may be skipped on some occasions, particularly if many photos are taken over a short period of time causing the camera buffer to fill up faster than the images are able to be written to the memory card. It is recommend that a fast memory card is used and to keep this side overlap fairly high for best results.
  • Target Speed - this is the speed in m/s that the aircraft will attempt to attain when flying out to begin the mission and when flying home.
    • The majority of a Panorama mission is spent stationary, rotating around a central point, so this setting has minimal effect on the overall mission time.
    • In most cases, the default is fine.
    • If you set this too fast, you may not have time to react in case of an incident where you need to take manual control.
    • 5m/s=18km/hr=11.2 miles/hr
  • Gimbal Angle - Set the gimbal angle (0=horizontal, 90=straight down). In most cases you want to take a Pano with a flat camera angle, but you may change it here. Note that you will not have manual gimbal control during flight, so select the correct angle here.
  • Review mission after creation - if you tick this, the app will remain on the Planning page once you have finished creating the mission, if ticked off, it will automatically return to the Fly page, ready for takeoff.
Once you are satisfied with these settings, press Next.

Step 2: Define location and orientation

After pressing next you will be presented with a screen like the following

Image

Using the graphical widget, you can set the arc, orientation and location of the panorama set.
  • The green aircraft icon sets the centre of rotation. This is the point at which the aircraft will hover and rotate to create the panorama.
  • The white handle ball in the middle of the blue arc can be dragged to set the orientation of the panorama.
  • The white handle balls on the edges of the arc can be dragged to change the arc of the panorama. In most cases 180 degrees is perfect, but you can select from 90 up to 360 degrees
Tip: To zoom in/out and move or rotate the map, you can use regular pinch/zoom or single finger drag gestures on an area of the map away from the panorama widget.

Tip: If you have zoomed in too far, finger gestures may not work correctly. In this case, use the  Image button at the top right of the screen to zoom out one step.

Once you are satisfied, press the blue OK button at the bottom right to go to step 3.

Step 3 - Multi level selection

The final step is to select the starting altitude and number and height of steps you would like to fly for your Panorama mission. The following dialog will slide in from the right of the screen.

Image

The key parts of the dialog are:
  • Lowest Altitude text box - enter the lowest altitude you would like to fly.
    • For a single level panorama (the default), this is the altitude at which the panorama will be taken.
    • For a multi level, this is the "bottom" panorama, other levels will be above this one
    • Altitude cannot be below the Min Safe Alt defined in step 1, or above the legal altitude limit of 120m
    • Remember - altitude is always measured relative to the takeoff (home) point.
  • Step count - using this slider, you can define how many steps the panorama should have.
    • Steps are inclusive of the Lowest Altitude. Thus if you select 2, 3m steps with a starting altitude of 50m, a Panorama will be taken at 53m and at 50m.
    • You can select from 1 to 8 steps
  • Step height - using this slider you can define how high each step is
    • Values range from a minimum of 3m to a maximum of 10m per step.
The upper altitude text field will be updated when you change any of these settings to show the extents of the mission vertically.

Tip: A Panorama mission is executed from the highest point to the lowest point, to better manage battery life.

When you are ready, press the FINISH button and the mission will be created.

Image

A panorama mission is displayed as a single waypoint on the map, which is the point around which the aircraft will rotate to take images. Press the up arrow at the bottom right of the screen to reveal the mission waypoints list. Here you will see that 3 waypoints were created for this 3 level mission. One waypoint for each level vertically. The altitude of the waypoints matches the 3m step height, plus the starting height of 50m, with the highest waypoint first.


Mission Statistics
After the mission is created, basic mission statistics are updated in the white strip beneath the map.

In the above case, the mission is 0.25km long, 15 pictures, 3:47 mins flight time (estimated) and will require one battery.

You have now completed creation of a panorama mission. When you are ready to fly, you may return to the Fly screen and takeoff to try out your mission.

Final tips for Panorama missions:
  • You can only fly a Panorama mission with the camera set to JPG or RAW (dng) . Video mode does not make sense for this type of mission. If you select video, the camera will automatically switch back to stills mode.
  • Keep the target speed slow so you can take control in the case of any unexpected event during flight.
  • This camera gimbal angle is managed by the drone based on your settings in step 1. You won't have manual control over the gimbal during a Panorama mission.
  • The drone does not take terrain into account in any mission type. All altitudes are relative to the takeoff point. Please ensure you set the Min Safe Alt high enough to avoid crashing into terrain, buildings, people or infrastructure at any point of the mission. You are responsible for the safety of your equipment and people and property around you.
WHAT IS THE HOME POINT?

A critical part of any mission is the Home point.
