Diagonal Vehicle Camera Layout for Two-Camera Bird's-Eye Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera monitor systems for vehicles require multiple cameras to capture a bird's-eye view, leading to increased electric power and system control demands.
Innovation Solution
Employing two imaging apparatuses with optical systems that form low-resolution regions near the optical axis and high-resolution regions outside, installed at diagonal corners of the vehicle to capture images for a bird's-eye view, using a configuration that reduces the number of cameras needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If at least four cameras are mounted on the vehicle to capture a bird's-eye video image, then the bird's-eye view imaging capability is achieved, but the electric power load and system control load increase
Solution Approach 1:
The patent combines the functions of multiple cameras into a single imaging apparatus equipped with a fisheye lens. This single apparatus captures images covering multiple directions (front, rear, left, right) simultaneously, replacing the need for four separate cameras and thereby reducing electric power consumption while maintaining bird's-eye view imaging capability
Solution Approach 2:
The imaging apparatus with fisheye lens serves multiple functions: it captures images in four different directions (front, rear, left, right) and provides both wide-angle coverage and sufficient resolution for bird's-eye view display. This multi-functional design eliminates the need for multiple dedicated cameras for each direction
2Reliability
If at least four cameras are mounted on the vehicle to capture a bird's-eye video image, then the bird's-eye view imaging capability is achieved, but the system control load increases
Solution Approach 1:
The patent merges four separate camera systems into a single imaging apparatus with fisheye lens. This consolidation reduces the number of devices from four to one, significantly simplifying system control architecture and reducing control load while maintaining the ability to capture images in all directions for bird's-eye view generation
Solution Approach 2:
The single imaging apparatus performs multiple functions that previously required four separate cameras: capturing front view, rear view, left side view, and right side view. This universal apparatus handles all imaging tasks with a single device, reducing system complexity and control requirements
