Adaptive Rear View Composite Image for Blind Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear view systems in vehicles, whether using mirrors or camera-supported systems, face limitations in providing an unobstructed and distraction-free view of the surroundings to the rear and side, particularly when changing direction, due to reduced mirror size and fragmented image displays.
Innovation Solution
A device and method that acquire images from multiple sensors and compose a seamless composite image on a display, dynamically adjusting based on travel direction and steering angle signals to prioritize relevant views, using cameras integrated into mirrors or bumper areas, and a control apparatus to manage image selection and display layout.

Engineering Contradiction Analysis
1Reliability
If camera-supported rear view systems display multiple image excerpts in partial sections, then the driver can see blind spots, but the display cannot be made sufficiently large and the numerous image excerpts distract the driver
Solution Approach 1:
The display area is segmented into a first display area for the primary rear view image and a second display area for the side view image excerpt. This segmentation allows the system to divide the complex information presentation into manageable sections, reducing overall display complexity while maintaining comprehensive monitoring capability.
Solution Approach 2:
Different regions of the display are assigned different functions and visual characteristics. The first display area shows the complete rear view with high priority, while the second display area shows the side view excerpt with lower priority. This local differentiation optimizes the visual presentation for each specific monitoring need without overwhelming the driver.
2Reliability
If mirrors have regions with differing degrees of convexity to view blind spots, then blind spot visibility improves, but the available mirror region for sensing rear surroundings is reduced
Solution Approach 1:
Instead of using physical mirrors with complex convex regions, the system uses camera sensors to capture images of the rear and side surroundings. These optical copies are then displayed electronically, eliminating the need for complex physical mirror geometries and maximizing the effective monitoring area.
Solution Approach 2:
The mechanical mirror system with varying convexity regions is replaced by an electronic imaging system using cameras and display apparatus. This substitution allows for flexible, dynamic adjustment of view areas without the physical constraints of mirror geometry, resolving the contradiction between blind spot coverage and available mirror area.

AI summary
A device for detecting and displaying the rear and/or side traffic of a motor vehicle is to be improved upon such that the driver can safely and quickly detect the present traffic situation by way of the overall image shown, in particular when the direction of travel is changed. This is accomplished in that the device for detecting and displaying the rear and/or side view of a motor vehicle (1) comprises a first apparatus (3) for producing images of the optically detected rear view (A), one or more further apparatuses (2) for producing images of the optical side view (B,C) of the motor vehicle (1), a display apparatus (6) adapted to display images or image sections of the first and/or the further apparatuses (2, 3) in partial areas (T1, T2), and a control apparatus (5) adapted to select the images or image sections and to assign them to the partial areas (T1, T2). The images or image sections are selected according to the signals of a driving direction indicator (7) and/or the signals of a sensor (8) that represents the steering direction and are assigned to the partial areas (T1, T2). Also provided is a method for detecting and displaying an overall image from an image section or overlapping image sections.
