Excavator Work Area Display Using Coordinate-Linked Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The need for operators to manually attach identification marks on objects for excavators degrades workability in recognizing work areas.
Innovation Solution
An excavator equipped with a display device that displays an image representing the work area, associating preset coordinates with image components, allowing for setting adjustments without manual marking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If identification marks are manually attached to objects in the work area, then the excavator can recognize predetermined objects and make settings relating to the work area, but the workability is degraded due to the manual marking requirement
Solution Approach 1:
The imaging device automatically captures images of the work area without requiring manual attachment of identification marks. The system processes these images to automatically recognize objects and determine work area boundaries, enabling the excavator to perform settings autonomously based on captured visual data rather than pre-marked physical identifiers
Solution Approach 2:
The manual mechanical process of attaching identification marks is replaced by an optical imaging system. The imaging device captures images, and the control device processes these images to identify objects and define work areas, substituting the mechanical marking approach with an optical-digital recognition system that eliminates the need for physical mark attachment
2Ease of operation
If coordinates are associated with image component portions, then setting adjustments can be made without manual marking, but the system complexity increases due to coordinate association requirements
Solution Approach 1:
A coordinate system serves as an intermediary between the image data captured by the imaging device and the work area settings. The control device establishes correspondence between image coordinates and real-world positions, enabling setting adjustments to be made by referencing coordinate information from captured images without requiring manual marking of the physical environment
Solution Approach 2:
The system creates a digital copy of the work area through image capture and coordinate association. Instead of modifying the physical environment with marks, the system generates a digital representation where settings can be adjusted by referencing coordinate information from the captured image, allowing virtual manipulation of work area parameters

AI summary
An excavator capable of making settings relating to the work area while considering the workability, is provided. The excavator 100 according to an embodiment of the present invention includes the display device D1 configured to display an image representing a work area around the excavator 100 (hereinafter "work area image"). The display device D1 is configured to display the work area image in such a state that coordinates that are preset with respect to the work area and an image component portion (for example, a pixel) included in the work area image are associated with each other, in a predetermined coordinate system.
