Vehicle Video System Simulated Overhead View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle video systems do not provide a comprehensive view of the cargo area, limiting the driver's ability to monitor the cargo and surrounding areas effectively, especially when the tailgate is open or a trailer is being connected.
Innovation Solution
A vehicle video system that includes a camera fixedly attached to the vehicle to capture video images of the cargo area, processing these images to generate a simulated overhead view, which is then displayed on an in-vehicle screen, allowing the driver to view the cargo area and surrounding spaces simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a rear camera is used to capture images of areas behind the vehicle, then the driver can observe the rear area during parking maneuvers, but the view is blocked when the tailgate is open or a trailer is connected
Solution Approach 1:
The system divides the monitoring function into multiple cameras: a rear camera for areas behind the vehicle and a cargo area camera for the cargo compartment. This segmentation allows each camera to specialize in a specific area, ensuring continuous visibility regardless of tailgate position or trailer connection status.
Solution Approach 2:
The cargo area camera serves multiple functions: it monitors the cargo area when the tailgate is closed, provides visibility when the tailgate is open (replacing the rear camera's function in that scenario), and enables overhead view generation. This multi-functionality ensures adaptability across different operating conditions.
2Loss of information
If multiple cameras are installed to provide comprehensive views, then the driver can monitor both the cargo area and surrounding spaces, but the system complexity increases
Solution Approach 1:
The system merges the functionality of multiple cameras into a unified overhead view display. The image processor combines images from the rear camera and cargo area camera to generate a single simulated overhead view, presenting comprehensive information in an integrated format that simplifies driver interpretation while maintaining complete surveillance coverage.
Solution Approach 2:
The system transforms two-dimensional camera images into a three-dimensional simulated overhead perspective. By processing images from multiple angles and generating a virtual overhead view, the system provides comprehensive spatial information in a format that intuitively represents the cargo area and surrounding spaces from a top-down perspective.

AI summary
A method for capturing and displaying images includes a plurality of operations. A first video camera is fixedly attached to a vehicle at a first fixed location in a prescribed orientation relative to a cargo area defined within a vehicle body structure of a vehicle. An electronic display is provided within the vehicle. Video images of the cargo area are captured using the first video camera. The video images of the cargo area captured by the first video camera are processed and a simulated video overhead view of the cargo area is generated. A still image representing an overhead view of the vehicle is displayed on the electronic display, and the generated simulated video overhead view of the cargo area is superimposed on the display over an area of the still image corresponding to the location of the cargo area.
