Facade scanner creates flight route to scan vertical objects. The calculation of the route is similar to Photogrammetry's tool only for vertical objects. It is implied, that the scanning zone is always rectangular, limited by vertical lines passing through A and B and horizontal lines on minimum and maximum height.

Parameter Control Description
Latitude Latitude input with ability to point on map Waypoint coordinates
Longitude Latitude input with ability to point on map Waypoint coordinates
Minimum height (AGL) Input field allowing to specify minimum height Specifies minimum height above ground relief

AGL only irrespective to route settings
Parameter is mandatory
Must be in a range of allowed altitude for the vehicle profile: between «Safe height over terrain» and «Max altitude, AGL» Must not be greater than «Maximum height (AGL)»

Maximum height (AGL) Input field allowing to specify maximum height Specifies maximum height above ground relief

AGL only irrespective to route settings.
Parameter is mandatory
Must be in a range of allowed altitude for the vehicle profile: between «Safe height over terrain» and «Max altitude, AGL» Must not be less than «Minimum height (AGL)»

Distance to facade Input field allowing to specify distance to facade Specifies drone distance to facade
Camera Drop down list containing cameras attached to the vehicle profile Parameter is mandatory
Forward overlap (%) Input field allowing to specify overlap in percentage Specifies overlap percentage between subsequent shots on a single forward pass

Default 60% Parameter is mandatory Must not exceed 90%

Side overlap (%) Input field allowing to specify overlap in percentage Specifies overlap percentage between shots on parallel forward passes

Default 60% Parameter is mandatory Must not exceed 90%

Pattern Drop down with two values:

• Horizontal • Vertical

Specifies scan pattern type

Default is vertical Parameter is mandatory

Vertical speed Input field allowing to specify vertical speed Specifies required vertical speed

Default maximum vertical speed from profile Parameter is mandatory Must not exceed maximum allowed vertical speed from profile

Horizontal speed Input field allowing to specify horizontal speed Specifies required horizontal speed

Default maximum horizontal speed from profile divided by 2 Parameter is mandatory Must not exceed maximum allowed horizontal speed from profile


Facade scan scaning zone is always a vertical rectangle with vertical (default) or horizontal flight pattern.

• During flight, the vehicle will always face facade;
• Turn type is Stop & turn
• «Camera by time» automatic triggering is calculated based on distance to the façade, camera FOV, vehicle speed (depending on the selected pattern vertical or horizontal)

After route is calculated successfully, message will show:
1. Facade scanning area, resulting GSD, step between forward passes
2. Calculated number of camera shots and interval between shots

Scanning will start from the corner of the rectangle, that is closest to first waypoint or if no waypoint is set before Facade scan - from left bottom corner.
Facade scan supported actions:
• Camera control
• Camera trigger
• Camera by time
• Wait.
