Night vision car

  1. 1. Presented by Gaurav GunjanGovt. Engg College,Bikaner
  2. 2.  Dual camera Amplifier On board display Caution ICU Intelligent night vision system Motion detection sensor
  3. 3.  Vehicle Speed Sensor Daylight Sensors Night Vision Sensor Vehicular Output Sensors
  4. 4.  A signal processor translates the thermo gram data to an image suitable for display on a monitor. the range of an FIR system was over three times further than that obtained with NIR — 119 m compared with 35 m.
  5. 5. • Near-infrard band at a wavelength of about 1 micrometer.• Human visual range is about 0.4 to 0.7 micrometers.• NVDs rely on ambient light, often from the moon and stars.•The intensifier tubes use the photoelectric effect.•As a photon collides with a detector plate, the metal ejects several electrons that are then amplified into a cascade of electrons that light up a phosphor screen.
  6. 6.  The night vision image does not have color information, and hence monochromatic displays are sufficient. A green phosphor (P22) display is generally used as the human eye is most sensitive to the color green in this wave length, which falls in the middle of the visible light spectrum. The latest generation of NVD use a green yellow Phosphor (P43), and gives the operator a much more comfortable viewing experience.
  7. 7.  Definition: 420 TV Lines Scan Frequency: 60Hz Minimum Illumination: 0 LUX 120 degree super wide viewing angle Size : 28mm x 42 mm Operation Temp : -20C ~ 50C Operating Voltage: DC 12- Volt Inside Mount: fits into most vehicle key holes Water Resistant Full Motion Real Time Colour Video without delay. Standard video output Increment Control: Auto
  8. 8. Analysis of US traffic fatalities by the University of Michigan Transport Research Institute (UMTRI) has shown : The risk of a pedestrian fatality is around four times higher at night than during daylight hours. Higher alcohol consumption, increased fatigue, greater exposure to animals on the road and reduced range of vision are some of the important factors owing to the same. One reason that driving at night is so difficult is that high-beam headlights can rarely be used owing to the frequent presence of oncoming traffic. Older drivers, who typically have shorter detection distances of just 30–50 m for dark objects when driving with low-beams and facing oncoming vehicles.
  9. 9.  Germanium and the chalcogenide glass GASIR from Umicore are potential lens materials. Germanium is a high-performance material for long-wavelength infrared lenses, with a high mechanical resistance and a refractive index of 4.0. GASIR is a new type of infrared-transmitting glass with a refractive index of 2.5. GASIR, unlike germanium, also possesses a refractive index that does not vary much with temperature, allowing for a simple opto- mechanical design that does not require temperature compensation. Single-point diamond turning process is required to machine it into an aspherical surface.
  10. 10.  Connect to any type of monitor with a composite yellow RCA jack for crystal clear resolution. Mounted inside will fit into most vehicle key holes, no other installation needed Small compact size Waterproof Low power consumption High sensitivity Low maintenance Easy and comprehensive installation
  11. 11. It has become the need of the hour to have these kindsof hybrid safety systems on the latest automobiles thatcould save the lives of many. Many such ideas are yet tocome and it is the duty of young budding engineers tothink innovatively and work upon developing suchtechniques one of which being the night vision sensorsused in cars and other automobiles that are proving to bea great success in the west and this should beimplemented immediately on the Indian terrain andreduce the catastrophic incidents that occur on the roadsespecially during the night times.
