Dual Display Rear Camera System Blind Spot Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems for rearward views often have blind spots due to limited field of view and lack of flexibility in presenting surroundings, which can hinder safe maneuvering.
Innovation Solution
A dual display system with two imagers and corresponding display devices in the vehicle's passenger compartment, controlled by a processor that captures and processes image data to provide two desired views, allowing for strategic overlap or different perspectives to eliminate blind spots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single imager and display device are used for rearward view, then the device complexity is low, but blind spots exist due to limited field of view
Solution Approach 1:
The system divides the rearward view into multiple fields of view by using multiple imagers (first imager, second imager) positioned at different locations. Each imager captures a specific portion of the rearward scene, and these segmented views are then processed and displayed together to form a comprehensive rearward view that eliminates blind spots.
Solution Approach 2:
The system transitions from a single two-dimensional display to a multi-dimensional viewing solution by using multiple imagers positioned at different spatial locations (e.g., rear bumper, rear quarter panels) and displaying their combined views. This spatial arrangement in multiple dimensions allows coverage of areas that would be blind spots in a single-view system.
2Reliability
If multiple imagers and display devices are used to eliminate blind spots, then the field of view and coverage are improved, but the device complexity increases
Solution Approach 1:
The system merges the image data from multiple imagers through image processing operations. The controller combines the first image data from the first imager and the second image data from the second imager, applying techniques such as stitching, blending, or selective display to create a unified comprehensive rearward view that enhances safety while managing system complexity through integrated processing.
3Adaptability or versatility
If the system provides fixed rearward views, then the device complexity is low, but the adaptability to different viewing needs is limited
Solution Approach 1:
The system implements dynamic adaptability by allowing the controller to selectively display different combinations of image data from the multiple imagers based on varying conditions. The display can dynamically adjust which views are shown, how they are combined, and their relative positioning, enabling adaptation to different maneuvering scenarios, vehicle types, and driver preferences without requiring fixed rigid configurations.

AI summary
A display system for a vehicle includes a first imager configured to capture image data in a field of view rearward of the vehicle. A second imager is also configured to capture image data in the field of view rearward of the vehicle. The display system additionally includes a first display device disposed in a passenger compartment of the vehicle and a second display device also disposed in the passenger compartment of the vehicle. The display system also includes a controller in communication with the first and second imagers and the first and second display devices wherein the controller is operable to adjust at least one of an orientation and a scale of two desired views of the image data for display on the first and second display devices.
