The thermal camera with Skydio X10 includes a powerful suite of tools, such as radiometric capabilities, to assist you in a variety of use cases.

 

Accessing thermal options

Quickly access your Thermal Tools, Settings, and Parameters using the quick action button located on the right side of the Flight Screen. 

  • Enable or disable Spot Measuring and Region of Interest
  • Cycle through thermal palettes 
  • Manually perform Flat Field Correction (FFC) 
  • Access all thermal settings

Flat Field Correction

Flat Field Correction (FFC) mitigates and compensates for errors that build up over time during the thermal camera operation. This is performed in the background automatically at lower zoom levels, however, you can use the Thermal Settings to manually perform FFC at any time.

[note] If you manually perform FFC, the actuation of the shutter may be noticeable on the image at higher zoom levels. [/note]

Thermal Tools

CS_App3_media_UI_thermal_tools_cropped_rounded.png

Isotherm 

Allows you to set a range of temperatures to detect. Use this setting to omit unwanted data outside of the specified range. The defined range will appear as the currently selected palette.

  • Temperatures outside of the defined range will appear as the default White Hot or Black Hot palette
  • If White Hot or Black Hot are currently selected, the temperatures in the Isotherm range will default to Rainbow

Spot Measuring

Enable to display the specific temperature value of an object on-screen as you drag your finger on-screen.

  • Tap or drag your finger across the screen to view temperatures

Region of Interest

Enable to display an on-screen box that detects the minimum, maximum, and average temperatures within the outlined area. 

  • represents the highest temperature detected
  • represents the lowest temperature detected
  • indicates the average temperature 
  • Select the edges of the box to resize, or use the arrows to drag the box to a different location

 

Thermal Settings

Color Palette

Visual representations of temperature variations captured by a thermal camera. 

Ironbow - Quickly identify varying temperatures and spot thermal anomalies. Displays a specific range of colors, from blues to reds, which indicate different temperature levels. 

  • Warmer objects are presented in lighter colors and colder objects in darker colors

Rainbow - Uses the colors of a traditional rainbow to distinguish between subtle variations in temperature levels. 

  • Covers a broader range of colors without emphasizing specific temperature ranges

White Hot - Provides a clear visualization of temperature variations without a variety of colors. 

  • Brighter, whiter colors indicate warmer temperatures
  • Darker colors represent cooler temperatuers

Black Hot - Displays the inverse of a White Hot palette. 

  • Brighter, whiter colors indicate cooler temperatures
  • Darker, black colors represent warmer temperatures

Thermal Mode

Adjust the signal amplification from the camera sensor to enhance temperature differences in an image.

  • Recon - Tuned to increase the contrast between the overall scene and targets. Best for search and rescue or situational awareness use cases. Recon helps differentiate the scene from things like people, vehicles, or animals.
  • Inspect - Tuned to decrease the overall contrast so that temperature anomalies are easier to identify in inspection use cases. This makes it easier to not only see the anomaly, but help track the source from the heat signature

Temp Range

Select the range of temperatures Skydio X10 will detect.

  • Narrow - Detects temperatures ranging from -40°F to 302°F (-40°C to 150°C)
  • Wide - Detects temperatures ranging from -40°F to 662°F (-40°C to 350°C)

Thermal Capture

Enable to capture thermal images as JPG files.

  • RJPG - When enabled, your drone will capture a Radiometric JPG in addition to a standard JPG. A Radiometric JPG includes the radiometric data within the photo file.

Custom Thermal Mode

The Custom option under Thermal Mode allows you to fine-tune your Gain, High Tail, and Low Tail settings:

  • Gain - Artificially increases contrast of areas with similar temperatures.
  • High Tail - Adjust saturation of the hotter items in the scene
  • Low Tail - Adjust saturation of colder items in the scene

Select Inspect or Recon as your Base Mode, then adjust your Gain, High Tail, and Low Tail settings from there. These settings will persist across flights and will be applied each time you select Custom as your Thermal Mode

Default Settings

  Recon Inspect Custom
Gain 6000 5000 Inherits value of base mode, then adjustable from there
High Tail 0.8 0.75 Inherits value of base mode, then adjustable from there
Low Tail 0.05 0.1 Inherits value of base mode, then adjustable from there

 

Thermal Parameters

Emissivity

The measure of how efficiently an object emits thermal radiation. Adjust to match the camera readings to the true temperature of the object.

  • Higher values means the camera is more sensitive to temperature variations
  • Lower values means the camera is less sensitive to temperature variations
Humidity

Set your humidity to accurately reflect the environment you are flying in. This should be the humidity between the sensor and the target.

Humidity is an important parameter to set because your thermal sensor will detect atmospheric conditions like humidity (and distance) which can affect the accuracy of your reading.

Distance

Set your distance to accurately reflect the range from your thermal sensor to the target.

The further away the target, the more atmosphere your thermal camera will pick up along the way to the target which can affect the accuracy of your reading.

More about emissivity

Surfaces that are better emitters (higher emissivity) provide more reliable temperature readings. For example, black electrical tape, rusted or oxidized surfaces, bodies of water, or human skin all absorb and emit energy. Set your emissivity high for these types of surfaces.

Reflective surfaces are not good emitters (low emissivity) and therefore not as reliable to measure. Stainless steel, shiny surfaces, or reflective windows tend to have a low emissivity. Set your emissivity low for these types of surfaces, but we recommend gathering your reading from a higher emissivity surface whenever possible.
