Vertical scan

The vertical scan creates a 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 the minimum and maximum height.

Parameter	Control	Discription
Turn type	Input field allow to change drone turn type	Stop & Turn* - defauld and safe turn Adaptive Bank Turn* - can be used ONLY by advanced pilot.
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 the distance to facade	Specifies drone distance to the facade
Camera	Drop down list containing cameras attached to the vehicle profile	Parameter is mandatory
Line Spacing: Side overlap (%)	Input field allowing to specify overlap in percentage	Specifies overlap percentage between subsequent shots on a single forward pass Default 50% Parameter is mandatory Must not exceed 90%
Line Spacing: Side distance (m)	Input field allowing to specify side distance in meters	Specifies side distance meters
Pattern	Dropdown 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
Follow terrain	Checkbox	Allows the UAV to automatically adjust altitude during flights based on current elevation
AGL Tolerance	Input field allowing to specify how precisely the UAV should follow required altitude above ground	To maintain specified height additional waypoints will be added if the difference of height is larger than AGL tolerance. The smaller the AGL tolerance value, the more amount of waypoints will be generated. If AGL tolerance is set 0 (zero) UAV’s altitude will be constant throughout the route, but many additional waypoints will be added.

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

After the route is calculated successfully, the message will show:

Vertical scan area, resulting GSD, step between forwarding passes
Calculated the number of camera shots and the interval between shots

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