Objects in the mirror are closer than they appear--this message is the tried and true safety warning that has reminded drivers for decades that their rearview mirrors are reflecting a slightly-distorted view of reality. Despite their limitations, mirrors are vital equipment on the car, helping drivers reverse or change lanes. But today, advanced driver assistance systems (ADAS) are going beyond a mirror’s reflection to give drivers an expanded view from the driver’s seat through the use of cameras.
Camera monitoring systems (CMS), also known as e-mirrors or smart mirrors, are designed to provide the experience of mirrors but with cameras and displays. Imagine looking into a rearview mirror display and seeing a panoramic view behind your vehicle. When you look to your side mirror, you see a high-resolution display showing the vehicles to your side. These scenarios are becoming reality, as are other features such as blind-spot detection and park assist.
