According to the National Safety Council of the United States, the risk of a fatal crash is three times greater at night when it is dark. Depth perception, color recognition and peripheral vision can be compromised in the dark. The nighttime vision issues may increase as we get older. Furthermore, the risk of accidents may increase at night because the driver may be more tired. Moreover, the glare of headlights from an oncoming vehicle can temporarily blind a driver. All of these issues may play a role in the increased fatality rates associated with driving at night.
Night vision systems may be used by drivers at night to see objects in relatively low light conditions. The use of a night vision system may be a possible solution for lowering the risks involved with night driving. Night vision systems may be active or passive systems. Active systems include a light source to shine light (non-visible light) in front of the vehicle and a camera to receive light reflected off any objects and a display to display those objects. The light source may provide infrared or near infrared light. A passive system does not require the light source. Rather, the camera is designed to detect thermal radiation that is emitted from objects and to display the thermal radiation detected.
Active and passive night vision systems have been incorporated into some high-end vehicles. The vehicles may not be affordable or desirable for all consumers. Furthermore, a system integrated with the vehicle cannot be used with other vehicles or in other situations.
Thus, what is needed is a night vision system that can be utilized on many different types of vehicles. The system may include a thermal camera that may be securely mounted to various locations on a vehicle. The thermal camera may be removed from a vehicle and used on other vehicles. The system may be capable of providing thermal images captured to a plurality of different display devices so that a user can use the type of display they desire.
