Volume dc2500, pp The results are presented below. Moreover, if the artificial fog is too dense 3the two persons in the background are only detectable in IR image 3.
For this test, we used a fog machine which can produce 40m3 of artificial fog per minute. The sensitivity bandwidth is comprised between 0. As presented in the theoretical part, an fllr sensor, composed of InGaAs, could produce images of a scene with poor visibility such as a scene with haze, fog and smoke.
ARGOS Project: Short Wave Infrared (SWIR) imaging
This technology could be used by the firefighters for seeing through the smoke during an intervention. Newer Post Older Post Home. This technology provides also a strong visibility at dusk and dawn hours. In video analytics, the SWIR imaging has advantages zc2500 extracting and locating features by using algorithms designed for visible spectrum.
FLIR Systems SC2500 Infrared Cameras
A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0.
Concerning video analytics, SWIR imaging sc25500 detection, recognition and identification of objects and persons.
For this test, we used a fog machine which can produce m3 of artificial fog per minute. 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. For example, hairs are more reflective in SWIR spectrum.
The duration of test is 30 minutes.
Thermal imaging camera / infrared / focal plane array / GigE – FLIR SC Series – FLIR SYSTEMS
A pass-band filter was added to the optical system sf2500 the FLIR camera for selecting the spectrum centered at wavelength around 1. Visible and SWIR streams were recorded from both cameras: The nightglow phenomenon allows also producing an image by night. Image Analysis and Processing.
The duration of test is nine minutes. A future experimentation would consist in generating images in SWIR spectrum of scenes with sc200 in real conditions.
In this work, the fog was simulated by machines. September th, Toulouse, 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. Differences in appearance between the visible and SWIR images are due to reflective material properties.
This test was done at indoor in a room of 15m2. 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 . Rameshwar M September 27, at 9: The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions.
These results are in agreement with previous works .
