A Research about the Design and Application of Double Spectrum Car Night Vision System

Abstract

With the rapid development of the automotive market and growing sense of security, the requirement of automotive safety is higher and higher. If infrared night vision system can be used, the view definition will be improved and the occurrence of traffic accidents will be reduced at night. The infrared night vision technology is a kind of photoelectric technology by using photoelectric imaging device to implement the night observation. Infrared imaging sensor identifies the target by detecting thermal radiation of the difference between target and background. Therefore, it is not sensitive to brightness changes of the sense and its imaging resolution is low. It is not conductive to human eyes observation. For driving safety, high resolution image is needed not only for finding the road object but also determining the accurate position of this road object. Optical imaging sensor resolution is high that can provide the road object's details. The fusion of the infrared and visible light image is conductive to comprehend the indicative of infrared image and the clarity of the visible light image, which is very important for driving safety. This paper implemented design of a kind of double spectrum car night vision system and described the novel competitive
