Thermal imaging camera / infrared / focal plane array / GigE – FLIR SC Series – FLIR SYSTEMS

The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions. In this work, the fog was simulated by machines.

In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images [2]. A future experimentation vlir consist in generating images in SWIR spectrum of scenes with smoke in real conditions. The nightglow phenomenon allows also producing an image by night. The duration of test is 30 minutes. For this test, we used a fog machine which can produce 40m3 of artificial fog per minute.

As presented in the theoretical part, an array sensor, composed of InGaAs, could produce images of a scene with poor visibility such as a scene with haze, fog and smoke.


A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0. As shows in Figure 3, the maximum radiant of nightglow in SWIR spectrum is similar at the radiant measured at 0.

This technology provides also a strong visibility at dusk and dawn hours. The sensitivity bandwidth is comprised between 0. Rameshwar M September 27, at 9: A pass-band filter was added to the optical system of the FLIR camera for selecting the spectrum centered at wavelength around 1.

The results are presented below. Moreover, if the sc5200 fog is too dense 3the two persons in the background are only detectable in IR image 3. Newer Post Older Post Home. Fkir test was done at indoor in a room of 15m2. Volumepp Image Analysis and Processing.

This technology could be used by the firefighters for seeing through the smoke during an intervention. These results are in agreement with previous works [3][4]. Another interesting point is that the phenomenon of nightglow, which is a very weak emission of light in the upper atmosphere, is more radiant in SWIR spectrum.

This test was done at outdoor in a garden composed of trees, grass and one path.

FLIR Systems SC2500 Infrared Cameras

For this test, we used a fog machine which can produce m3 of artificial fog per minute. Differences in appearance between the visible and SWIR images are due to reflective material properties. September th, Toulouse, The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust and smoke.

The duration of test is nine minutes. We observe in Figure 5 that the person disappears in the fog in the visible image while the same person is still visible in the SWIR image 2. Visible and SWIR streams were recorded from both cameras: Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons. For example, hairs are more reflective sc25000 SWIR spectrum.

In video analytics, the SWIR imaging has advantages for extracting and locating features by using algorithms designed for visible spectrum.
