Omniview technology (also known as surround view or bird view) is a vehicle parking assistant technology that first was introduced in 2007 as the "Around View Monitor" option for the Nissan Elgrand and Infiniti EX. It is designed to assist drivers in monitoring their surroundings, for example, while parking a vehicle in a small space.


Principle

Early vehicle parking assistant products used ultrasonic parking sensors and/or a single rear-view camera to view and obtain distances to objects surrounding the vehicle, providing drivers with an audible alarm or rear-view video through a fisheye lens. There are some drawbacks to these early products: the alarm only provides a proximity warning but not the position of the object(s) relative to the vehicle, and the rear-view camera has a limited field of view. However, omniview technology overcomes these problems and has seen increasing availability.

The four cameras have overlapping fields of view that collectively cover the whole area around the vehicle and serve as an

from above the vehicle by stitching the video feeds together, correcting distortion, and transforming the perspective. In some cases, ultrasonic sensors are used in combination with the omniview system to provide distance information and highlight the relevant view that may be affected by potential obstacles. Because the bird's-eye view is a simulated perspective using camera inputs much closer to the ground, objects at ground level will appear relatively undistorted while those above the ground will appear to "lean away" from the vehicle. In addition, if the same object is captured by the overlapping fields of two cameras, it can appear to lean away in two different directions.


History

The first vehicle equipped with Nissan's "Around View Monitor" was the Japanese-market Elgrand, introduced in November 2007. In America, the system was introduced one month later, as an option for the EX35 from Nissan's luxury marque Infiniti. At about the same time, Mitsubishi Motors and Honda implemented similar functionality as the "Multi-around monitor system" for the

An omniview system that uses four cameras and displays a three-dimensional rendering of the vehicle and its surroundings has been proposed as a logical next step to increase the driver's awareness.direct URL
