Work Machine Display Layout for Overhead and Specific Camera Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work machines, such as excavators, face difficulties in intuitively understanding various types of information related to the operation due to the limited display of overhead images.
Innovation Solution
A work machine control method and system that acquires images from multiple cameras and displays an overhead image in a first region of the display screen, with additional specific images shown in a second region, allowing for a clearer and more intuitive understanding of the machine's operation by dividing the display screen into cutout regions corresponding to the machine's plan view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an overhead image is displayed on a display device, then the operator can see the work machine operation, but it is difficult for the operator to intuitively understand various types of information on the operation
Solution Approach 1:
The display screen is divided into multiple display regions, with the first display region showing the overhead image and the second display region showing the specific image. This segmentation allows different types of information to be presented in separate areas, making it easier for the operator to intuitively understand various operation information without confusion.
Solution Approach 2:
The patent introduces a new dimension to the display by adding the second display region that shows a specific image (such as a blind spot image or detection target image) in addition to the overhead image. This multi-dimensional display approach provides comprehensive information from different perspectives, enhancing the operator's understanding of the work machine operation.
2Loss of information
If multiple images are displayed to provide comprehensive information, then the operator understanding improves, but the display screen becomes more complex
Solution Approach 1:
The display screen is segmented into distinct regions (first display region for overhead image, second display region for specific image), allowing multiple images to be organized in a structured manner. This segmentation provides comprehensive information while maintaining a clear and organized display structure that does not excessively increase complexity.
Solution Approach 2:
The display device performs multiple functions by showing both the overhead image and the specific image simultaneously. This multi-functionality allows the single display device to provide comprehensive operation information without requiring multiple separate display devices, thus avoiding excessive complexity.

AI summary
A work machine control method includes acquiring a captured image of a monitored area around a work machine, causing an overhead image based on the captured image to be displayed in a first display region, and causing at least part of a specific image to be displayed in a second display region. The first display region is a region that is part of a display screen displayed on a display device and that has a shape obtained by cutting out, as a cutout region, a portion of the display screen in a circumferential direction as viewed from an own machine reference position that corresponds to a position of the work machine in plan view. The second display region is a region that is part of the display screen and that is located in the cutout region.
