In video analytics, the SWIR imaging has advantages for extracting and locating features by using algorithms designed for visible spectrum. The results are presented below.
The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust and smoke. This test was done at outdoor in a garden composed of trees, grass and one path. Image Analysis and Processing. Moreover, if the artificial fog is too dense 3the two persons in the background are only detectable in IR image 3.
These results are in agreement with previous works . A future experimentation would consist in generating images in SWIR spectrum of scenes with smoke in real conditions.
Volumepp 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.

In this work, the fog was simulated sc5200 machines. For this test, we used a fog machine which can produce m3 of artificial fog per minute.
In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images .
The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions. Differences in appearance between the visible and SWIR images are due to reflective material properties. The duration of test is 30 minutes.

For example, hairs are more reflective in SWIR spectrum. Newer Post Older Post Home. This test was done at indoor in a room of 15m2.
Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons. 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. This technology could be used by the firefighters for seeing through the smoke during an intervention. 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: The sensitivity bandwidth is comprised between 0. Rameshwar M September 27, at 9: A pass-band filter was added to the optical system of sc250 FLIR camera for selecting the spectrum centered at wavelength around 1.
This technology provides also a strong visibility at dusk and dawn hours. For this test, we used a fog machine which can produce 40m3 of artificial fog per minute. September th, Toulouse, A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0.
We observe in Figure 5 that the person disappears in the fog in the visible image while the same person is still visible fir the SWIR image 2.
