The duration of test is 30 minutes.
A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0.
In video analytics, dlir SWIR imaging has advantages for extracting and locating features by using algorithms designed for visible spectrum. In this work, the fog was simulated by machines.
This technology could be used by the firefighters for seeing through the smoke during an intervention.
ARGOS Project: Short Wave Infrared (SWIR) imaging
The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust and smoke. These results are in agreement with previous works . The experimentations, sc25000 in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions. For this test, we used a fog machine which can produce m3 of artificial fog per minute. The sensitivity bandwidth is comprised between 0.

The nightglow phenomenon allows also producing an image by night. 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.
A future experimentation would wc2500 in generating images in SWIR spectrum of scenes with smoke in real conditions.
For this test, we used a fog machine which can produce 40m3 of artificial fog per minute. Newer Post Older Post Home.
For example, hairs are more reflective in SWIR spectrum. 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 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. This technology provides also a strong visibility at dusk and dawn hours. Image Analysis and Processing.
This test was done at outdoor in a garden composed of trees, grass and one path. In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images .
This test was done at indoor in a room of 15m2.
Moreover, if the artificial fog is too dense 3the two persons in the background are only detectable in IR image 3. As shows in Figure 3, the maximum radiant of nightglow in SWIR spectrum is similar at the radiant measured at 0. Visible and SWIR streams were recorded from both cameras: September th, Toulouse, The results are presented below. A pass-band filter was added to the optical system of the FLIR camera for fkir the spectrum centered at wavelength around 1.
Volumepp Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons. flur
Differences in appearance between the visible and SWIR images are due to reflective material properties. Rameshwar M September 27, at 9:
