Work Machine Monitoring Display With Fixed Detection Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators find it difficult to intuitively recognize detection targets, such as people, in the monitoring area due to the large amount of information displayed on the screen in existing work machine control systems.
Innovation Solution
A work machine control method and system that acquires and displays captured images of the monitoring area, with a detection object consistently shown at the same position on the screen, changing its display mode based on detection results, allowing for easier recognition of detection targets.

Engineering Contradiction Analysis
1Measurement precision
If a periphery monitoring system displays detailed detection information including yellow/red circles and area highlighting, then detection accuracy is improved, but operator recognition difficulty increases due to information overload
Solution Approach 1:
The detection information is segmented into distinct visual elements: detection markers (circles) are separated from the captured image, and area highlighting is separated from the detection marker. This segmentation allows the operator to process information hierarchically, first locating detection markers and then examining detailed information, thereby reducing cognitive load while maintaining detection accuracy.
Solution Approach 2:
Different visual properties are applied to different parts of the detection information: detection markers use color (yellow/red) to indicate detection status, while area highlighting uses transparency and positioning to show spatial relationships. This local differentiation of visual qualities helps operators quickly distinguish between detection status and spatial information without creating a uniform information overload.
2Loss of information
If multiple detection markers and area highlights are displayed simultaneously, then detection information completeness is improved, but visual clutter increases making intuitive recognition difficult
Solution Approach 1:
The detection marker is extracted as a separate visual element from the captured image and area highlight. This extraction allows the detection marker to be positioned at a standardized location (center of the display or superimposed on the captured image) without interfering with the area highlight, thereby maintaining information completeness while reducing visual clutter through spatial separation.
Solution Approach 2:
The detection information is organized across multiple dimensions: the captured image provides spatial context, detection markers provide detection status in the foreground, and area highlights provide boundary information in the background. This multi-dimensional organization allows complete detection information to be displayed without creating a flat, cluttered interface, as elements are layered in different visual planes.

AI summary
[Problem] To provide a work machine control method, a work machine control program, a work machine control system, and work machine that enable an operator to easily and intuitively recognize that a detection target is present in a monitoring area. [Solution] The work machine control method includes acquiring captured images Im11, Im12, and Im 13 of a monitoring area around a work machine, and displaying a display screen Dp1 including the captured images Im11, Im12, and Im13 and a detection object Im10 on a display device. The work machine control method further includes displaying the detection object Im10 at an identical position on the display screen Dp1 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 Im10 according to the detection result.
