A pass-band filter was added to the optical system of the FLIR camera for selecting the spectrum centered at wavelength around 1. The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions.
Newer Post Older Post Home. Rameshwar M September 27, at 9: For this test, we used a fog machine which can produce 40m3 of artificial fog per minute. 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 fllir of test is nine minutes. In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images . In video analytics, the SWIR imaging has advantages for ssc2500 and locating features by using algorithms designed for visible spectrum.

A future experimentation would consist in generating images in SWIR spectrum of scenes with smoke in real conditions. This technology could be used by the firefighters for seeing through the smoke during an intervention. The sensitivity dlir is comprised between 0.
In this work, the fog was simulated by machines. Volumepp These results are in agreement with previous works . The results are presented below.
The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust 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. Lfir example, hairs are more reflective in SWIR spectrum. Visible and SWIR streams were recorded from both cameras: Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons.
Image Analysis and Processing. 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. September th, Toulouse, A high-pass filter was added to the optical system of the Fir camera for selecting the wavelengths comprised between 0.
This test was done at outdoor in a sc500 composed of trees, grass and one path. For this test, we used a fog machine which can produce m3 of artificial fog per minute. Differences in appearance between the visible and SWIR images are due to reflective material properties. This technology provides also a strong visibility at dusk and dawn hours.
As shows in Figure 3, the maximum sc2500 of nightglow in SWIR spectrum is similar at the radiant measured at 0.
The nightglow phenomenon allows also producing an image by night. This test was done at indoor in a room of 15m2. The duration of test is 30 minutes. Flie, if the artificial fog is too dense 3the two persons in the background are only detectable in IR image 3.
