Drone Amplified
Estimated photo overlap:
Calculates how much of your photos will overlap, given the
current settings and assuming the drone maintains a constant altitude above ground
level. Adjusting this slider will modify the transect spacing, cruise speed, and time
between photos (if necessary) to achieve the specified overlap.
Camera:
This selects the field of view parameters to use for displaying the expected region
covered by the photos. If a DJI camera like a Zenmuse XT2 is connected, you’ll seen an
option for that camera displayed. The app knows the advertised field of view for many
DJI cameras, and will use those if you pick that camera. However, some cameras may
have variations in lenses, models, or optical zoom, and so if the app’s field of view values
are inaccurate, you should use the Custom Parameters option. You can verify whether
the app’s field of view values for the camera are accurate by moving the gimbal around
and viewing the app’s augmented reality HUD. If the N, NE, E, SE, etc. overlays cover the
same feature in the video feed regardless of how the gimbal is oriented, then the app has
the correct field of view values for the camera.
Horizontal Field of View:
This displays the left-right field of view measurement of the
camera. This is only used to estimate how much area the photos will cover, and affects
the amount of overlap between transect lines. If the Custom Parameters option is
selected, there will be a slider that you can use to adjust this.
Vertical Field of View:
This displays the top-bottom field of view measurement of the
camera. This is only used to estimate how much area the photos will cover, and affects
the amount of overlap along the same transect line. If the Custom Parameters option is
selected, there will be a slider that you can use to adjust this.
A workflow for planning and flying a mapping mission is as follows:
1. Define region extents:
Touch the transects button to open the Transect Region menu,
then touch the map at the corners of the region you wish to map to specify the region’s
extents. You may want to cover a slightly larger area to ensure you have overlapping
photos of the entire area.
2. Set zig-zag Heading:
Open the transect settings. Adjust the Zig-zag heading slider so
the transects will be flown along the desired direction. Also make sure the arrow points
towards the landing location so that the drone doesn’t have to fly far if it’s low on
battery at the end of the mission.
