1. Linear: Scene radiation is mapped to pixel values where color is uniformly distributed from one shade to another as pixel intensity increases. These palettes are the most common palettes for general use: WhiteHot, BlackHot, GreenHot, Fusion, Ironbow
2. Contrast: Enhances observed contrast by mapping pixel values to divergent color schemes. Subtle differences between object temperatures become more apparent. Lava, Arctic.
3. Alert: Helps draw attention to the hottest subjects in a scene by applying high-contrast color values to an otherwise linear distribution. GreyRed, InstAlert.

• Period: Delay between captured images. Range: 1 – 60 seconds.
• Playback Speed: Framerate still images are replayed. Range: 1 – 60 frames per second.

• Video File Type: Select MJPEG, H.264 or TIFF. See Section 6 for more details.
• Analog Video Format: Select NTSC or PAL as the format of the video that is output to the 10-pin mini USB port. This setting does not affect the format of the video that is saved to the microSD card.
• Still Image Type: Select formats for still images and video saved to the microSD card (See Section 6).
• Flip Horizontal/Vertical: Select image orientation. To mount the camera upside down, flip both Horizontal and Vertical. For a rear-facing application (and the effect of looking at a rearview mirror), flip only horizontal.
• Speaker on Record Stop: Turns on/off the audible indicator for video recording. Even when turned off, the speaker will beep three times when the camera is ready after powerup.
• Speaker on Still Image Record: Turns on/off the audible indicator. Even when turned off, the speaker will beep three times when the camera is ready after power-up.
• Enable LED: Turns on/off the Status and Bluetooth LEDs. LED indicators will still be displayed while camera is booting up if this setting is turned off.

• MAVLink: Many UAS light controllers support the MAVLink serial protocol to provide an interface with external components. The Vue Pro can be conigured to use this bus to capture available telemetry data provided by GPS, altimeter, accelerometers, etc. This data is saved as standard EXIF metadata in Still Image iles ()PEG & TIFF). This data is not saved to Video iles as there is no current standard for doing this. Metadata is accessible thru standard photo editing applications, ile explorers, and suggested mapping applications (see section 6.3).

The following MAVLink 3.0 commands are currently supported by the Vue Pro FW 1.2.4:

FLIR Vue Pro communicates on the MAVLink bus at 57600 baud which is standard for most devices. Where possible, ensure RTSCTS is disabled as this is known to cause issues with communication. The included Accessory Port cable PN 4142156 is pre-terminated to connect properly with the 3DR PixHawk TELEM 1 port. If this port is already in use, see the PixHawk documentation for information on how to reconigure ports. If all available light controller ports are full, you may need to investigate using a splitter cable to attach additional devices. Please refer to Table 1 for Accessory Port pin-out when building custom cables.
Vue Pro can operate in a receive only coniguration much like an OSD, and therefore does not require the TX pin from the camera to be connected to the RX pin on a light controller. Please note that some light controllers (3DR Solo) will sleep a serial port if no connection is detected. Please plan accordingly when setting up your system.
Please see Appendix B for the full MAVLink protocol implementation.
5.1.8.3 Radiometry
The Radiometry tab provides access to all the temperature measurement functions and settings available on the Vue Pro R. If connecting to a standard Vue Pro camera, this tab will not be visible and these features are unavailable. See FLIR’s UAS Radiometry Tech Note (see Section 2.2 for the link) for a detailed discussion on how to obtain accurate temperature readings for UAS applications.

• Temperature Unit – Units of measure displayed on the analog video. Select between Celsius and Fahrenheit.
• Temperature Range – This setting adjusts the camera sensitivity and dynamic range to provide optimum image quality. When in Auto mode the camera analyzes the scene and selects between states, based on scene conditions. Ambient temperature of the camera influences the performance of this setting. However, approximate detectable temperature ranges are as follows:
  • -25/+135°C (-13/+275°F)
  • -40/+550°C (-40/+1022°F)
    Unless extreme temperatures are expected to be encountered (i.e. fires), keep this setting configured in the Auto position.
• Spot Meter – Turns on or off the spot meter (fixed 4×4 pixel array) in the center of the image, the on-screen thermometer on the left edge of the image, and the digital temperature in the lower left corner of the image (Figure 18). The spot consists of a 4×4 pixel array that is averaged to provide the measurement.
• Scene Meter – The Min and Max temperatures in the center 75% of the scene are actively identified and labeled by 4×4 pixel indicators. The specific values of these points are provided on screen in the lower left hand corner, and color coded to the labeled points in the image (Figure 19). There is approximately 1 second of latency to process the scene which can lead to some lag and should be considered during use.
• OT Still – Records a still image any time the Max: value in the Scene Meter is greater than the threshold. Values from 0 to 300° C (32 to 572° F) can be configured. The feature can also be disabled by setting it to Off.
• OT Alert – When a temperature in the scene is detected that is greater than the threshold, the Max: Scene Meter label flashes. Values from 0 to 300° C (32 to 572° F) can be configured. The feature can also be disabled by setting it to Off.
• Emissivity – Measure of the target surface ability to emit thermal energy. Values from 50- 100% can be configured.
• Air Temp. – Ambient temperature of the operating environment. Values from 0 to 40° C (32 to 104° F) can be configured.
• Sky Condition – Measure of the cloud cover above the operating site. This affects the background radiation incident on the scene. Clear, Scattered and Cloudy are input values.
• Humidity – Relative moisture content of the air. Three settings are available; Low (30%), Medium (45%), High (60%).
• Target Range – Distance from the camera to the target in the scene. Values from 0-200m (0- 218 yards) can be configured.

• Part Number – FLIR part number of the Vue Pro camera currently connected to the app.
• Serial Number – Vue Pro camera serial number currently connected to the app.
• Firmware Version – Version of firmware currently loaded in the Vue Pro camera.
• FW Upgrade Version – Detects if a camera upgrade file exists on the microSD card. If one is available, the Upgrade Available dialog will start. Choose Yes to begin the upgrade process.
  See Appendix A for details on how to upgrade camera firmware.
• App Version – Version of software currently loaded on the mobile device.
• App Upgrade Version – If the mobile device is connected to the Internet, the Vue Pro app will automatically search for any available app updates. If one exists, the user will have the option to update by following the link to the FLIR web page.
• Persistent Bluetooth – Prevents the Bluetooth interface from shutting off after 2 minutes.
• Reset To Factory Defaults – Resets settings in the Vue Pro camera to original factory configuration. This is required during most FW updates as the internal memory map will change as new features are added.
• Disable Bluetooth: Powers down the Bluetooth radio on the camera. The camera will normally disable the Bluetooth after two minutes of inactivity. See Persistent Bluetooth.
• Bluetooth Power – Adjusts the Bluetooth transmitter power and affects the maximum range at which the Vue Pro camera can connect to the mobile device. Power values are expressed in percent.

File Formats

The Vue Pro can save image data in a number of ile formats, each with unique characteristics.
6.1 JPEG
The JPEG format of the Vue Pro has both the compressed 8-bit processed JPG image and 14-bit raw sensor data ina single ile. The 8-bit image has Scene and Palette processing applied. If a compatible light controller is available telemetry will be captured and saved in standard metadata ields.
6.2 TIFF 
TIFF is uncompressed 14-bit raw sensor data with no post processing. If a compatible light controller is available telemetry will be captured and saved in standard metadata ields.

Care of FLIR Vue Pro

• Only power FLIR Vue Pro with a regulated 5 Vdc power source. Using more than 6 Vdc will damage the camera and void the warranty.
• Do not touch the lens. If the lens gets dirty, a light dusting of air should dislodge any dust particles. If the lens is still noticeably dirty, use 75% Isopropyl alcohol and lens tissue. Use a light wiping motions with a fresh section of lens tissue with each swipe so as not to drag dust or dirt particles back over the lens surface.
• Do not remove the lens. Dirt and dust can settle on the interior surfaces of the camera and degrade performance.
• FLIR Vue and Vue Pro cameras have been focused at the factory and optimized for the maximum range performance of each camera/lens pair using a collimated bar target. Although it is possible to adjust the focus, doing so may compromise the external seal of the camera and factory focus will be lost. A special tool is required in order to prevent damage to the lens housing or front detector element.
• FLIR Vue Pro is neither water nor dust resistant. Care for it as you would any valuable piece of electronics equipment.

Appendix A – Software and Firmware Update

How to update Firmware (FW)

1. Backup Vue Pro settings. Connect to the Vue Pro with the Bluetooth application and make note of all your settings. The firmware upgrade will reset the camera settings to defaults since we typically are adding features and the previous settings may not be optimal for your application.
2. Download firmware update. Download then save the firmware upgrade onto the camera micro SD card either by connecting yourVue Pro to a computer with the included Bench cable, or through another suitable micro SD card reader.
3. Power on Vue Pro. Power on the Vue Pro and wait for it to complete the boot cycle (you’ll hear the three beeps and see the Bluetooth light go steady blue and the Record light go steady red). If the Bluetooth radio does not enable, press the button to turn it on. You will see a blue light.
4. Start update process. Open the Vue Pro app and connect to the camera. The app will read the camera’s settings, then display the Firmware update message (Figure 22). Select “Yes” to begin the update. The Bluetooth light will flash purple for 30-45 seconds while it’s updating, then the camera will re-boot. During this time, you will see an Upgrading message, and then the Bluetooth disconnect message. It is important to NOT remove power to the camera during the upgrade process.
5. Reconnect via Bluetooth. Once rebooted, reconnect your handset to the camera by selecting ‘Yes’ from the Bluetooth Disconnect dialogue (). The camera should reconnect and present you with the Main screen. If you previously selected ‘No’ in this dialogue you will need to force quit and restart the APP on your handset.
6. Reset to factory defaults. This step is very important so please do not forget to perform the task. Select the Advanced button in the lower left of the screen, then the About tab, and finally ‘Reset to Factory Defaults’ button. A warning box will be presented, please select ‘Yes’. All the files on the micro SD card will be preserved, only the flash memory on the Vue Pro camera will be reset. This will ensure proper operation of the camera with the new firmware.
7. Restore User Settings. From your notes in Step 1 reconfigure any Main, PWM or Accessory Port settings for your specific application. You can also delete the firmware update file from your microSD card.
