Work Vehicle Overhead Image Synthesis for Variable Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicle systems struggle to provide an intuitive and comprehensive overhead image of the periphery, including work equipment, due to distortion and inadequate coverage, especially when equipment of varying sizes is attached, leading to inefficient monitoring and potential operational hazards.
Innovation Solution
A work vehicle equipped with multiple cameras and a modular image synthesis system that adjusts the synthesizing pattern based on the size and orientation of attached work equipment, using recognition units and user input to generate an optimized overhead image displayed on a touch panel, ensuring accurate and user-friendly peripheral monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the overhead image is adapted to small work equipment, then the monitoring coverage for small equipment is adequate, but large work equipment cannot be fully included in the overhead image
Solution Approach 1:
The synthesizing pattern is made dynamically adjustable based on the detected type of work equipment. The system automatically modifies the synthesizing pattern according to whether small or large work equipment is attached to the vehicle body, enabling the overhead image to adapt its coverage area and composition dynamically. This resolves the contradiction by making the monitoring system flexible rather than fixed, allowing adequate coverage for both small and large equipment types.
Solution Approach 2:
The system changes the parameters of the synthesizing pattern (such as image composition, coverage area, and display proportions) based on the detected work equipment type. By modifying these parameters dynamically, the overhead image can be optimized for different equipment sizes, ensuring that small equipment is fully monitored while large equipment can also be completely included when attached.
2Adaptability or versatility
If the overhead image is adapted to large work equipment, then large work equipment can be fully included, but an area that requires no monitoring becomes large and display area is wasted
Solution Approach 1:
The synthesizing pattern dynamically adjusts its parameters based on the detected work equipment type. When large work equipment is detected, the system modifies the pattern to include the equipment fully while minimizing unnecessary empty areas. This dynamic adaptation ensures that the display area is used efficiently without wasting space on areas that require no monitoring.
Solution Approach 2:
The system modifies the synthesizing pattern parameters (such as image composition, coverage area, and display proportions) according to the detected equipment type. This parameter adjustment optimizes the use of display area by including only the necessary monitoring regions, thereby reducing wasted space while maintaining complete coverage of large work equipment.
3Device complexity
If a fixed synthesizing pattern is used, then the system complexity is low, but the overhead image cannot accommodate varying work equipment sizes and orientations
Solution Approach 1:
The system implements a dynamic synthesizing pattern that automatically adjusts based on the detected work equipment type. This dynamic approach increases adaptability to different equipment sizes and orientations while maintaining reasonable system complexity through automated detection and pattern selection, eliminating the need for manual configuration.
Solution Approach 2:
The system performs self-service by automatically detecting the work equipment type and selecting the appropriate synthesizing pattern without requiring manual intervention. This self-adjusting capability enhances adaptability to varying equipment configurations while keeping the system complexity manageable through automated decision-making algorithms.
4Area of stationary object
If the overhead image coverage area is expanded to include large work equipment, then complete equipment coverage is achieved, but the distortion increases and specific components become difficult to see
Solution Approach 1:
The system changes the synthesizing pattern parameters based on the detected work equipment type. When large work equipment is detected, the pattern is modified to optimize both coverage area and image detail clarity. This parameter adjustment ensures that specific components remain visible and distinguishable while achieving complete coverage of the large equipment.
Solution Approach 2:
The synthesizing pattern applies local quality adjustments by modifying different regions of the overhead image according to the detected equipment type. This allows optimal detail clarity in critical areas while maintaining comprehensive coverage, resolving the contradiction between expanded coverage and component visibility.
