Use Thermal Analysis to analyze the temperatures of up to four points or regions in a thermal video taken using the FLIR ONE® Thermal Camera for iOS. The video is taken at about 8 frames per second. Temperature resolution is set to 0.1°C.
To start, open the Thermal Analysis app and tap the + sign to start a new experiment. The app will prompt you to connect the FLIR ONE camera. Once you connect the camera, turn it on. The LED on the camera's power button turns amber when you first press it, then after a few seconds it starts flashing green to indicate that the camera is ready. The app will display a thermal image.
Add a Thermometer
Tap the image where you would like the thermometer to be placed. Drag the thermometer to reposition it. A single pixel at the intersection of the two cursor lines is used to measure temperature. Pull the bottom right corner of the thermometer to expand this to a region. Scroll or tap the AVG/MIN/MAX legend to change the region from measuring average temperature in that area to measuring minimum or maximum temperature of that area.
Remove a Thermometer
Drag a thermometer to the trash can in the lower right corner of the video.
Tap the Record button to start and stop collecting data. Temperatures vs. time are graphed during the experiment.
When the experiment ends, choose to Save or Discard Video.
Tap the i to rename the experiment.
The location, type, and number of thermometers can be changed after a video is captured. The graph will take a short time to update based on the new configuration. The graph mode can also be changed after a video is captured.
The graph includes a vertical cursor located at the time of current frame. Tap the graph to place the cursor and video at a different time.
Delete the Experiment
Swipe left in the experiment name bar to reveal the Delete button.
Tap the Share button to export a single frame of the video, the entire original video, a video with thermometers and graphs, or files for Graphical Analysis or Logger Pro.
Frame exports a still image of just the thermal frame, with no thermometers showing and no graph. The image is placed in the Photos app.
Video exports a thermal video, with no thermometers or graph. The video is placed in the Photos app.
Video with Graph exports a thermal video and graph, in which the vertical cursor on the graph tracks with the video frames.
Data file exports a .cmbl file via email or AirDrop for opening in Logger Pro, or you can open the file in Graphical Analysis by choosing Open in and choosing Copy to Graphical.
Data File with Video exports a .cmbl file and a video file. Save both files into the same folder and open the .cmbl file in Logger Pro. The Logger Pro file will include the thermal video as well as the data.
On iPhone or iPod, tap the gear to access the settings. Tap the gear again to hide the settings. On iPad, the settings are always visible.
Change the color scheme that is used in the thermal video.
Change the range of temperatures that are measured in the thermal video. This feature is useful for making small variations in temperature obvious in the video. This feature is not available on older iOS devices.
If you are using the FLIR ONE® Thermal Camera oriented so that it is facing toward you, this feature allows the camera to mirror your motion.
Use this setting to align the thermal image with the outline provided by the visible light camera. This feature is not available on older iOS devices.
Change from °C to °F or K.
Default lets you track up to four thermometers separately. The thermometers can be spots or rectangular regions.
Line creates four equally-spaced spot thermometers.
Delta pairs two spot thermometers or regions and graphs the difference between the temperatures measured. Up to two pairs of temperatures can be compared at once.
