Work Machine Route Display for Remote Depth Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When remotely operating a work machine, the two-dimensional image display leads to a poor sense of perspective, making it difficult for operators to accurately gauge the distance between working equipment and work objects, which can lower work efficiency.
Innovation Solution
An image display system that calculates the position of working equipment and displays a route image in a form that differs when viewed from a predetermined position, depending on whether the route is shielded by the equipment, thereby enhancing depth perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a two-dimensional image display is used for remote operation, then the operation system is simple, but the sense of perspective is poor and distance perception is difficult
Solution Approach 1:
The patent applies dimensionality change by displaying the route image in different forms based on whether it is shielded by working equipment. Specifically, shielded portions are displayed with transparency or different visual characteristics while unshielded portions use normal display, creating a multi-dimensional visual representation that conveys depth and spatial relationships on a two-dimensional screen, thereby improving distance perception without adding complex hardware
2Loss of information
If work support information is projected in front of the cab, then information visibility is improved, but depth information cannot be effectively communicated on a two-dimensional screen
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of different portions of the route image based on their spatial relationship with the working equipment. Shielded portions are displayed with distinct visual properties (such as transparency or different coloring) while unshielded portions maintain normal display characteristics, allowing depth information to be communicated through localized variations in the visual presentation

AI summary
There are provided a position calculator that determines a position of working equipment included in a work machine, a display that displays a route image corresponding to a route through which the working equipment moves, and a display processor that causes, on the basis of a position of the route and a position of the working equipment determined by the position calculator, the display to display the route image corresponding to a portion of the route that is shielded by the working equipment with a predetermined position serving as a viewpoint in a form different from the route image corresponding to a portion of the route that is not shielded by the working equipment.
