Work Vehicle Camera Overlays for Intuitive Task Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-camera vision systems for work vehicles often fail to provide operators with intuitive and comprehensive views of their surroundings, leading to increased mental workload and heads-down time, as they typically offer specific and limited camera feeds that do not accommodate the diverse operational needs of different machines and environments.
Innovation Solution
A multi-camera vision system with cameras mounted at various locations on the work vehicle, coupled with a controller and display devices within the operator cabin, which selectively displays feeds with overlays indicating the origin and orientation of each camera, allowing operators to intuitively navigate and understand multiple camera feeds, thereby reducing the need for frequent adjustments and improving visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple camera feeds are displayed without contextual information, then the system provides comprehensive views, but the operator experiences increased mental workload and difficulty in understanding feed origins
Solution Approach 1:
The patent introduces contextual information overlays as an intermediary element between the camera feeds and the operator. These overlays provide origin and orientation data without requiring the operator to mentally process raw feed information, thereby reducing mental workload while maintaining comprehensive surveillance capability
Solution Approach 2:
The system creates simplified representations (overlays) of camera feed metadata that are superimposed on the actual feeds. These copies convey essential contextual information (origin, orientation) in an easily digestible format, reducing the cognitive burden on operators while preserving complete visual information
2Ease of operation
If specific camera feeds are selected for display, then the system reduces information complexity, but it fails to accommodate diverse operational needs of different machines and environments
Solution Approach 1:
The patent implements a universal display framework that can accommodate multiple camera feeds from different machines and operational contexts. The system is designed to handle diverse feed types and configurations while maintaining a consistent interface, allowing it to adapt to various operational needs without requiring machine-specific customization
Solution Approach 2:
The system dynamically adjusts which camera feeds are displayed based on operational context, machine type, and environmental conditions. This dynamic selection process maintains information simplicity by showing only relevant feeds while preserving versatility to accommodate any operational scenario through adaptive feed prioritization
3Adaptability or versatility
If operators frequently adjust camera feed selections, then the system can adapt to changing task requirements, but operator efficiency decreases due to increased heads-down time
Solution Approach 1:
The system automatically manages camera feed selection and configuration based on detected operational context and task requirements. This self-service capability eliminates the need for operators to manually adjust feed selections, allowing the system to adapt to changing tasks autonomously while operators maintain focus on primary work activities
Solution Approach 2:
The system continuously monitors operational parameters and task context, using this feedback to automatically adjust which camera feeds are displayed. This closed-loop approach ensures the display adapts to task requirements in real-time without operator intervention, maintaining both adaptability and productivity

AI summary
A multi-camera vision system is utilized onboard a work vehicle having an operator cabin and an apparatus associated with performance of a work task. The system includes: one or more display devices defining a plurality of display areas and a plurality of cameras carried by the work vehicle and coupled to display feeds at the display areas. A first camera of the cameras is oriented to selectively provide a first selected feed of at least a portion of the apparatus during performance of the work task. A controller is configured to display the first selected feed of the selected feeds with an insert, overlay, or icon that indicates the origin and orientation of the first camera as the first selected feed depicts performance of the work task by the apparatus.
