Embodiment

[0115] Example: When the left and right displays fail, the center display is used to divide the left and right images into two regions.

[0116] The left and right monitors have the same resolution: Width: Wl / r Height: Hl / r

[0117] The resolution of the central display is: Wc Hc

[0118] The segmentation of the central display cannot affect the original visual field requirements of the central display;

[0119] The left and right displays are divided into two types: driving field of view and extended field of view. The loss of magnification should be minimized under the premise of meeting the legal field of view.

[0120] In general, determining roiW and roiH means knowing where to capture the image from the l / r camera. Then determine CSizeh and CSizew also know how to capture from the central display.

Abstract

The invention discloses a CMS screen display exception redundancy processing method based on functional safety requirements, which comprises the following steps of: obtaining a view distance and a view width of an area 1 corresponding to laws and regulations through the laws and regulations, representing the view distance of the area 1 by A1L, and representing the view width of the area 1 by A1W; the invention relates to the technical field of vehicle-mounted camera shooting, and according to the application method of the display screen failure on cms, when a left display and a right display fail, a central display is used for dividing two areas to display a left image and a right image. The segmentation of the central display cannot influence the original visual field requirement of the central display; display of the left and right displays is divided into a driving view field and an extended view field, and loss of magnification times should be reduced as much as possible on the premise of meeting the regulatory view field. The roiW and the roiH are determined, i.e., what position the image was captured from the l / r camera is known. And then, how to capture the CSizeh and the CSizew from the central display is known if the CSizeh and the CSizew are determined.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted cameras, in particular to an application method of display screen failure on cms. Background technique [0002] In terms of use, CMS is an indirect vision device used to replace traditional rear-view mirrors in automobiles. With the emergence of new technologies such as intelligent networking, autonomous driving, and ADAS, cars are developing rapidly in the direction of electronics and intelligence, and the rearview mirror of the car is also developing. In the future, rearview mirrors will be allowed to be replaced, cameras and monitors will be added. A combination of will be used to solve the rear vision problem. Using the Camera Monitor System (CMS) to replace standard-mandated rear-view mirrors can help reduce vehicle air resistance, reduce blind spots, and improve visibility in harsh environments. At the same time, cameras that replace rear-view mirrors can integrate ADAS and intelli...
