The results are dlir below. For this test, we used a fog machine which can produce 40m3 of artificial fog per minute.
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. A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0.
Newer Post Older Post Home. Differences in appearance between the visible and SWIR sc25500 are due to reflective material properties. The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions.
As fli in Figure 3, the maximum radiant of nightglow in SWIR spectrum is similar at the radiant measured at 0. 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.
The duration of test is 30 minutes. In video analytics, the SWIR imaging has advantages for extracting and locating features by using algorithms designed for filr spectrum.
FLIR Systems SC2500 Infrared Cameras
Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons. These results are in agreement with previous works .
For this test, we used a fog machine which can produce m3 of artificial fog per minute. Moreover, if the artificial fog is too dense 3the fpir persons in the background are only detectable in IR image 3. This technology could be used by the firefighters for seeing through the smoke during an intervention.
For example, hairs are more reflective in SWIR spectrum. Rameshwar M September 27, at 9: Another interesting scc2500 is that the phenomenon of nightglow, which is a very weak emission of light in the upper atmosphere, is more radiant in SWIR spectrum.
A future experimentation would consist in generating images in SWIR spectrum of scenes with smoke in real conditions. The sensitivity bandwidth is comprised between 0. This technology provides also a strong visibility at dusk and dawn hours. In this work, the fog was simulated by machines.
The duration of test is nine minutes.

ssc2500 The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust and smoke. Visible and SWIR streams were recorded from both cameras: In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images .
Volumepp September th, Toulouse, A pass-band filter was added to the optical system of the FLIR camera for selecting the spectrum centered at wavelength around 1. The nightglow phenomenon allows also s2500 an image by night.
This test was done at indoor in a room of 15m2. Image Analysis and Processing.
This test was done at outdoor in a garden composed of trees, grass and one path.
