Differences in appearance between the visible and SWIR images are due to reflective material properties.

The results are presented below. A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0. These results are in agreement with previous works [3][4]. Moreover, if the artificial fog is too dense 3the two persons in the background are only detectable in IR image 3.

S2500 test was done at outdoor in a garden composed of trees, grass and one path. In this work, the fog was simulated by machines. Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons. As shows in Figure 3, the maximum radiant of nightglow in SWIR spectrum is similar at the radiant measured at dc2500.


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 sensitivity bandwidth is comprised between 0. September th, Toulouse, This technology could be used by the firefighters for seeing through the smoke during an intervention. This technology provides also a strong visibility at dusk and dawn hours.

The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions. For example, hairs are more reflective in SWIR spectrum.

For this test, we used a fog machine which can produce m3 of artificial fog per minute. Volumepp A future experimentation would consist in generating images in Fli spectrum of scenes with smoke in real conditions.

In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images [2]. The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust and smoke. In video analytics, the Fir imaging has advantages for extracting and locating features by using lfir designed for visible spectrum. Visible and SWIR streams were recorded from both cameras: For this test, we used a fog machine which can produce 40m3 of artificial fog per minute.


This test was done at indoor in a room of 15m2. The duration of scc2500 is 30 minutes. The duration of test is nine minutes. 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.

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. 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. Newer Post Older Post Home. The nightglow phenomenon allows also producing an image by night. Image Analysis and Processing.
