NIGHT VISION SYSTEM IN AUTOMOBILES

1. A seminar on “NIGHT VISION System in AUTOMOBILES ” SUBMITTED BY: ANJALI B.TECH 3 rd year 127364008

2. Introduction Principle of Operation Working Advantages and Disadvantages Present Day Applications Conclusion CONTENTS

3. An automotive night vision system is a system to increase a vehicle driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights . The first car night vision system was implemented on the Cadillac 2000 DeVille , which used infrared technology to detect pedestrians. INTRODUCTION

4. NIGHT VISION SYSTEM IN AUTOMOBILES works on two phenomenon :- ACTIVE ILLUMINATION THERMAL IMAGING PRINCIPLE OF OPERATION

5. This system can detect pedestrians up to four times farther than the typical headlight range even in penetrating dense smoke. It actively detects people near the roadway, highlighting potential hazards and allowing drivers to have more time to react to them. Its high beam illumination warns the pedestrians as well. ACTIVE ILLUMINATION

6. Thermal imaging is a heat-sensing technology that can see in complete darkness using temperature difference. Electrical impulses are sent in the form of temperature values to an image signal processor that turns them into video data for presentation on a display. THERMAL IMAGING

7. CAR WITH NVS MECHANISM

8. Systems use an LCD that's mounted on the dash, in the instrument cluster, or integrated into the head unit. The front thermo graphic sensors detects the heat and processes the thermo grams to display images on LCD. The IR sensor attached in vehicle's grille illuminates very high beam. WORKING

9. REPRESENTATION The Night Vision system will warn the driver if a pedestrian is present in the danger zone (marked in red) in front of the vehicle.

10. Reduce accidents . G reater range of about 300 meters or 1,000 feet . Can be switched on or off and doesn’t affect driving style Works in almost every weather conditions. ADVANTAGES OF NVS

11. Higher cost of process Large quantity of costly and complex equipments. W orks poorly in warmer weather conditions L arger sensors are required DISADVANTAGES OF NVS

12. Audi, BMW uses thermal imaging PRESENT DAY APPLICATION

13. Mercedes-Benz uses active illumination

14. “ The innovation and implementation of night vision system has a great impact on automotive session such as saving many lives from death reducing accidents at night. ” CONCLUSION
