3D Scan capture settings overview
Published: Updated:
Settings will persist between scans of the same capture mode and through power cycles. If you would like to restore settings back to default, select the reset button in the top right on the workflow pane during the Review or Edit Settings steps of a scan.
[note] GPS will be required for scans higher than 65 ft (20 m). [/note]

Photo Settings Based on the available lighting conditions, your drone will automatically adjust photo settings to ensure it captures the best quality images. You will see in-app notifications alerting you if there are problems with the lighting conditions. For consistency with reconstructions, Skydio recommends leaving all photo settings set to default. If needed you do have the ability to adjust the following:
DNG must be enabled for each independent 3D Scan and your settings will NOT persist. DNG photos can only be captured when 'Stop for Photo' is enabled. If you enable DNG capture this will automatically toggle Stop for Photo. |
|
* When Photo Interval is enabled your drone will continuously capture photos at the specified time interval until the setting is disabled or the flight ends. Available in the Manual Capture step of a 3D Capture. *** DNG photos are not displayed in the media tab of the Skydio Enterprise app and may be retrieved directly from the microSD card. |
|
Overlap Percentage Overlap between photos along a path. The default overlap is 80%; high overlap is recommended for complex scenes. Sidelap Percentage Sidelap between two adjacent flight paths. The default sidelap is 70%; high sidelap is recommended for complex scenes. |
|
Stop for Photo By default, the drone will fly through image capture points without stopping for smooth and efficient flight.
Toggle this setting on if you would like Skydio to stop before capturing a photo at each capture point.

Capturing thermal images Thermal images are enabled by default. If you are flying with a Skydio X2 Color/Thermal, you have the ability to enable or disable thermal image capture in the camera settings.

Scan Passes Organizes the capture path into three continuous slices, Z, Y, and X. The Z slices are completed first and resemble orbits at fixed heights going around the structure. By default, the camera gimbal angle is set to 15°. Use the Z Gimbal Pitch slider to adjust the camera angle at which the drone will capture photos while orbiting. Increased gimbal pitch results in capturing less sky and more photos of the surrounding area and structure itself. Read How to use scan slices in 3D Scan for more detailed information. |
[info] The camera gimbal pitch represents the angle below the horizon. [/info]
Distance to Surface
Determines how close the drone will fly to the structure or area being scanned. Smaller distance to surface (closer) means more photos taken and higher resolution, with an increased total scan time. The Distance to Surface corresponds directly to Ground Sample Distance (GSD) which defines the distance between two consecutive pixel centers on the ground. For example, a one-millimeter GSD would suggest that the distance of the two consecutive pixel centers in the photo reflects one millimeter on the ground.

Default settings are optimized for 3D reconstruction.
If your main objective is to create a 3D reconstruction using a third party photogrammetry software, review the table below for example settings.
Example 3D Capture Settings
Industry | Use Case | Artifacts to Detect | Example GSD | Scan Pass | Overlap/Sidelap |
Construction | Progress monitoring and asset inspection | Asset damage, misalignment, as-built vs. design | 2 mm | Z, Y, X | 80/70 |
Transportation | Bridge inspection | Cracks and delamination in concrete, bolts, nuts, connection points in weight bearing areas | 1 mm | Z, Y, X | 80/80 |
Utilities | Distribution | Transformers, conductors, insulators, static wire, pole quality/damage | 1 mm | Z |
80/75 |
Telecommunications | Cell tower with complex antenna array | RAD Centers, connection points, access ladder conditions | 1.5 mm | Z, Y or X | 85/80 |
If your objective is only to capture highly detailed imagery (without later processing), you can decrease the overlap and sidelap percentages (e.g. 30-50% overlap/sidelap) to significantly speed up scan time.
Use Case Example: Key Requirements for Transmission & Distribution Inspection
Distance to Surface |
Set to achieve up to 0.5 centimeter precision (GSD) |
Overlap/Sidelap |
30%/30% overlap/sidelap from multiple angles of the tower infrastructure |

Settings will persist between scans of the same capture mode and through power cycles. If you would like to restore settings back to default, select the refresh arrow in the top right on the workflow pane during the Review or Edit Settings step of a scan.
Perimeter Scan 3D volumes by traversing the 2D perimeter at multiple heights and taking pictures inward.
Adjust the Gimbal Angle slider to your desired camera angle. The gimbal angle range for the Perimeter setting is 0-90 degrees. |
|
Crosshatch Capture oblique images by enabling the Crosshatch setting. When enabled, Skydio will capture in a rotating lawn mower pattern.
When disabled, the drone will capture photos in a nadir lawn mower pattern. Adjust the Gimbal Angle slider to your desired camera angle. The gimbal angle range for the Crosshatch setting is 55-85 degrees. |
[info] The camera gimbal pitch represents the angle below the horizon. [/info]
Height
The most important setting for 2D Captures. Lower height means more photos taken and higher resolution, but an increased total scan time.
In a 2D Capture, the Height is relative to the Floor you set. The Height corresponds directly to Ground Sample Distance (GSD). Set the Height higher than the slider options by piloting the drone to your desired height and tapping the Set Height to Current button.

Default settings are optimized for 2D orthomosaic generation in 2D and Map Capture. Your GSD will adjust based on your altitude settings. Higher overlap and sidelap percentages result in longer scans and a greater number of photos. You have the ability to adjust these settings before the scan begins.
If your goal is to create a high fidelity reconstruction, increase your overlap and sidelap percentages. If you do not plan to create a model of your scan, lower overlap and sidelap percentages will suffice.
Example 2D / Map Capture Settings
Industry | Use Case | Objective | Example GSD | Cross Hatch / Perimeter | Overlap/Sidelap |
Construction | Site survey, stockpile volumetrics | Site progress, volumetrics, terrain model | 10 mm | Cross Hatch | 75/70 |
First responder | Large collision scene reconstruction | Crumple damage, skid marks, weapons, broken glass | 1 mm | Cross Hatch | 80/75 |
Transportation | Road grading and survey | Cracks and delamination in concrete, road damage, erosion, site survey, terrain model | 10 mm | Default (off) | 75/70 |
