Vehicle Mirror Replacement Display With Offset Virtual Camera Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems with camera feeds are limited by fixed camera positions, restricting the information available to operators and failing to provide comprehensive views, especially in scenarios where traditional mirrors or cameras are obstructed.
Innovation Solution
A system incorporating multiple cameras and sensors generates extrapolated images from virtual camera positions offset from the vehicle, using an extrapolation algorithm to create enhanced views, including obstructed object transparency and manual or automatic adjustment of virtual camera positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple cameras and extrapolation algorithms are used to generate virtual camera views, then operator awareness and visibility are improved, but device complexity increases
Solution Approach 1:
The system creates virtual camera views by generating extrapolated images that copy and extend the visual information from physical cameras. The extrapolation algorithm synthesizes additional perspective views that do not require physical cameras at those positions, effectively copying the visual field from available camera feeds to create comprehensive operator awareness.
Solution Approach 2:
The extrapolation algorithm acts as an intermediary between the physical cameras and the display system. It processes raw camera feeds and transforms them into virtual camera perspectives, mediating the conversion of limited physical sensor data into comprehensive multi-angle visual information for the operator.
2Adaptability or versatility
If virtual camera positions are made adjustable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system transitions from fixed virtual camera positions to dynamically adjustable positions. Operators can modify virtual camera parameters in real-time, allowing the system to adapt to different operational scenarios and preferences without requiring physical reconfiguration of camera hardware.
Solution Approach 2:
The virtual camera system serves multiple functions: it can display from various fixed positions, allow manual adjustment, and potentially combine with sensor data. This multi-functionality enables a single system to handle diverse viewing requirements without needing separate dedicated systems for each function.
3Area of stationary object
If extrapolation algorithms generate views from offset positions, then comprehensive coverage is improved, but measurement precision requirements increase
Solution Approach 1:
The system extends the visual field by generating views from virtual camera positions offset from the vehicle in multiple spatial dimensions. This creates comprehensive coverage of areas that would be blind spots for single-position cameras, effectively adding dimensional coverage without physical camera placement at every angle.

AI summary
A mirror replacement system for a motor vehicle includes a plurality of cameras (22,24) disposed about a vehicle. A vehicle controller is connected to each camera and includes an extrapolation algorithm configured to generate at least one extrapolated image based at least in part on an image feed from the plurality of cameras. The extrapolated image is from the perspective of a virtual camera position (50, 50′, 50″) offset from the vehicle. A display is configured to display the extrapolated image to a vehicle operator.
