FLIR Boson performances

ANAFI USA carries a 60 Hz FLIR Boson micro-bolometer. This module is equipped with a mechanical shutter which enables automatic recalibration of the sensor as often as possible, for a complete consistence of each thermal pixel’s response. The lens of the FLIR Boson has a 50° HFOV.

 

Coloring modes

ANAFI USA’s thermographic camera presents two complementary coloring modes, which enables the drone to adapt to every mission.

 

Relative mode

The relative mode displays a general view of the thermographic of a scene, on a colored scale, graduated from 0 (dark blue) to 100 (bright yellow).

Spot mode

Only coldest or hottest spots of the image are colorized, depending on the user’s needs.

Thermal analyzer mode

The Thermal analyzer feature of FreeFlight 6 provides you with a great tool to achieve quick thermal analysis, directly from your device.

 

This function gives you full control over the on-screen rendering of any thermography video or photo you have taken with ANAFI USA. From the analyzer, you can:

 

  • access Thermal Preferences directly from the preview’s Preferences icon, top right;
  • navigate inside your thermography videos;
  • modify the thermography modes (Relative, hot and cold spots) and their associated thresholds at any point of any video or on any photo;
  • modify the blending between Visible and Thermal spectrums;
  • save as many screenshots as you want.

The photo displays or the video plays in Analyzer mode. As shown on the following screen captures (extracted from a video analysis), the interface gives you access to most options available for filming.

IR/Visible blending

To compensate the lower resolution of the thermographic image, by comparison with the visible image, and to add information that are not available through the thermal spectrum, ANAFI USA displays a fusion of the information of the two cameras. The data of the visible image is injected in the outcome footage, by luminance and to highlight the scene’s contours.

 

The fusion of images consists in:

 

  • acquisition of visible image;
  • acquisition of thermographic data;
  • reprojection of thermographic data;
  • colorization of thermographic image;
  • extraction of visible images contours;
  • mixing.
