Work Machine Monitoring Display for Intuitive Target Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators find it difficult to intuitively recognize detection targets, such as people, in the monitoring area of work machines due to the large amount of information displayed on the screen.
Innovation Solution
A work machine control method that acquires and displays captured images of the monitoring area, with a detection object consistently shown at the same position on the screen, while changing its display mode based on detection results, allowing for easier recognition of detection targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a periphery monitoring system displays detailed detection information (yellow/red circles, colored areas) for each detected person, then detection accuracy is improved, but the display becomes complex and operators cannot intuitively recognize detection targets
Solution Approach 1:
The patent extracts the essential detection information (presence/absence of detection targets) from the complex periphery monitoring display and presents it separately through the work area display. Instead of showing all detailed monitoring information, it selectively displays only the necessary detection target positions and types in the work area view, reducing cognitive load while maintaining detection accuracy.
Solution Approach 2:
The display system is segmented into multiple views: the periphery monitoring display shows detailed detection information with colored circles and areas, while the work area display shows a simplified overview with detection target icons. This segmentation allows operators to access detailed information when needed while maintaining an intuitive overview during normal operation.
2Reliability
If comprehensive periphery monitoring information is displayed, then safety monitoring is improved, but information overload makes it difficult for operators to quickly recognize detection targets
Solution Approach 1:
The display dynamically adjusts the level of information presented based on operational context. The work area display provides a simplified, intuitive view for normal operation, while the periphery monitoring display provides comprehensive detailed information when operators need to verify detection results or investigate specific areas.
3Measurement precision
If detailed detection markers and colored areas are displayed in the periphery monitoring system, then detection precision is improved, but the overall system complexity increases
Solution Approach 1:
The system implements partial display of detection information in the work area view, showing only essential detection target positions and types rather than complete monitoring details. Full detection precision is maintained in the periphery monitoring display, allowing operators to access complete information when needed while keeping the primary work area display simple and intuitive.

AI summary
The work machine control method includes acquiring captured images of a monitoring area around a work machine, and displaying a display screen including the captured images and a detection object on a display device. The work machine control method further includes displaying the detection object at an identical position on the display screen regardless of a detection result of a detector that detects a detection target in the monitoring area, while changing a display mode of the detection object according to the detection result.
