  3. INTRODUCTION – NIGHT VISION • ‘Night Vision’ literally means ‘to see in low-light conditions’ • The technology which allows the people to see clearly in a dark environment is called as ‘Night Vision Technology’ 3
  4. GENERATION 0 • Required invisible infrared light GENERATION 1 • Three image intensifier tubes were used GENERATION 2 • Used Image Intensification technique GENERATION 3 • Evolution of micro channel plate GENERATION 4 • ‘Filmless and Gated’ image intensifiers GENERATIONS OF NIGHT VISION 4
  5. Image Enhancement o Collects tiny amounts of light, including the lower portion of the infrared light spectrum and amplifies it o The gathered light is sent to the image-intensifier tube Thermal Imaging o Operates by capturing the upper portion of the infrared light spectrum o Focused light is scanned by a phased array of infrared- detector elements TECHNOLOGIES OF NIGHT VISION 5

  7. PROPOSED SYSTEM - PEDESTRIAN DETECTION Tracking • The motion of the vehicle or pedestrian Merging of blob • Separating blobs from objects Detection of blob • Block identifying process Edge Detection • Smoothing processed images Segmentation • Multiple segments of image Frames • Extracted from input video Input Video • Captured using camera 7

  11. IMPLEMENTATION - IMAGES 11
  12.  The thermal image is converted first by the sensor into electrical signals.  The higher the temperature, the higher the electrical signal and the whiter the pixel will be shown.  From a physical standpoint, this represents electromagnetic waves with a wavelength of 8 μm to 15 μm. This long-wave infrared radiation is known as Far Infrared (FIR).  Essentially, FIR systems consist of an optical element, a thermal imaging camera, a control unit and a display. OPERATION PRINCIPLES 12
  13.  It has improved the vision conditions of dusk and darkness.  There is no dazzling by head lights of the oncoming vehicles.  It ensures the highlighting of illuminated, heat-emitting objects as pedestrian, cyclists, etc.  It illuminates the bends/curves.  It has superior image quality.  It provides an uninterrupted image. ADVANTAGES OF PROPOSED SYSTEM 13
  14.  The advancement of this technology along with the GPS(Global Positioning System) Navigation will bring about the advent of driverless vehicle.  Effective night vision could be the key parameter in such vehicles.  This technology will probably be applied in hidden object detection and wildlife observations. FUTURE ASPECTS 14
