In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images . This lfir could be used by the firefighters for seeing through the smoke during an intervention.
Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons.
In this work, the fog was simulated by machines. The sensitivity bandwidth is comprised between 0. Differences in appearance between the visible and SWIR images are due to reflective material properties.

For this test, we used a fog machine which can produce m3 of artificial fog per minute. Image Analysis and Processing. 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. These results are in agreement with previous works . Volumepp Moreover, if the artificial fog is too dense 3the two persons in the background are only detectable in IR image 3. The nightglow phenomenon allows also producing an image by night.
September th, Toulouse, The duration of test is nine minutes. This test was done at indoor in a room of 15m2.
This technology provides also a strong visibility at dusk and dawn hours. This test was done at outdoor in a garden composed of trees, grass and one path.
A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0.

A zc2500 experimentation would consist in generating images in SWIR spectrum of scenes with smoke in real conditions. As shows in Figure 3, the maximum radiant of nightglow in SWIR spectrum is similar at the radiant measured at 0. 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.
The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions.
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 pass-band filter was added to the optical system of the FLIR camera for selecting dc2500 spectrum centered at wavelength around 1. Visible and SWIR streams were recorded from both cameras: The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust and smoke. The results are presented below. Newer Post Older Post Home. In video analytics, the SWIR imaging has advantages for extracting and locating features by using algorithms designed for visible spectrum. Rameshwar M September 27, at 9: For example, hairs are more reflective in SWIR spectrum.
The duration of test is 30 minutes.
