Night vision technology was developed by the US defense department mainly for defense purposes ,but with the development of technology night vision devices are being used in day to day lives. In this seminar of mine I wish to bring out the various principles of working of these devices that have changed the outlook both on the warfront and in our common lives. Night Vision can work in two different ways depending on the technology used. 1.Image enhancement- This works by collecting the tiny amounts of light including the lower portion o ....etc

Machine vision refers to applications in which the PC automatically makes a decision based on visual input from a camera. Machine vision is a term typically used in industrial manufacturing, where applications range from culling blemished oranges from a conveyor belt to saving lives by inspecting to ensure that the correct drug capsule has been placed in the package before the product is shipped to the pharmacy. Three dimensional vision based measurement systems have made their presence into production metrology applications, notably in the el ....etc

LucentVision is a real-time networked visual information system that archives sports action using visual processing. The system provides a variety of visual and textual content-based queries on the archived information, and presents the query results in multiple forms including animated visualization of court coverage and virtual-replay of action from arbitrary viewpoints. LucentVision analysis include presence maps that show where the players spent their time during a match (top picture), virtual replays (bottom picture) in which a ball trajec ....etc

VISION BASED PROCESSING FOR REAL TIME 3-D DATA ACQUISITION BASED CODE STRUCTURED LIGHT

Abstract: The structured light vision system is a successfully used for the measurement of 3D surface in vision. There is some limitation in the above scheme, that is tens of picture are captured to recover a 3D sense. This paper presents an idea for real-time Acquisition of 3-D surface data by a specially coded vision system. To achieve 3-D measurement for a dynamic scene, the data acquisition must be performed with only a single image. A principle of uni ....etc

Night Vision technology consists of two major types: image intensification (light amplification) and thermal imaging (infrared). Most consumer night vision products are light amplifying devices. Light amplification technology takes the small amount of light, such as moonlight or starlight, that is in the surrounding area, and converts the light energy (scientists call it photons), into electrical energy (electrons). These electrons pass through a thin disk that's about the size of a quarter and contains over 10 million channels. As the electron ....etc

NIGHT VISION TECHNOLOGY
ABSTRACT

A night vision device (NVD) is an optical installment that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies, but are available to civilian users. The term usually refer ....etc

Bio-Medical Instrumenation Field of Vision is the term used for the measurement of vision or for the test used to measure exact vision. A person s uncorrected vision refers to the visual acuity without glasse or contactlenses.




The eye s optical system is very complex. For best vision, light must travel through an undistorted cornea, a normal lens and other clear media before reaching a healthy retina, connected to the brain by the visual pathway. We really see with our brain, not the eyes. When trying to understand this concept abo ....etc

The first thing you probably think of when you see the words night vision is a spy or action movie you've seen, in which someone straps on a pair of night-vision goggles to find someone else in a dark building on a moonless night. And you may have wondered Do those things really work? Can you actually see in the dark?


The answer is most definitely yes. With the proper night-vision equipment, you can see a person standing over 200 yards (183 m) away on a moonless, cloudy night! Night vision can work in two very different ways, depending ....etc
