Remote Work Vehicle Display Alignment for Intuitive Tilt Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators remotely controlling work vehicles face difficulty in intuitively recognizing the inclination of the vehicle due to non-intuitive display orientations, especially when the display screen is not aligned with the operator's line of sight.
Innovation Solution
A display control system that includes a captured image acquisition unit, a posture image acquisition unit, a display image generation unit, and a display control unit to generate and display a posture image representing the work vehicle's roll and pitch angles in a manner that aligns with the operator's view, ensuring the inclination is intuitively recognizable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is oriented obliquely or laterally with respect to the operator's seat, then the operator can view the captured image, but the operator cannot intuitively recognize the inclination of the work vehicle
Solution Approach 1:
The patent applies dimensionality change by rotating the level image by 90 degrees to match the oblique orientation of the display screen. Instead of changing the physical orientation of the display screen itself, the solution transforms the level image into a different dimensional orientation (rotated 90 degrees) so that it aligns with the screen's viewing angle, allowing intuitive inclination recognition without requiring the screen to be positioned differently
Solution Approach 2:
The patent changes the orientation parameter of the level image from the standard horizontal/vertical alignment to a 90-degree rotated alignment. This parameter change allows the level image to correspond with the oblique orientation of the display screen, resolving the contradiction between screen orientation and inclination recognition accuracy
2Adaptability or versatility
If the level image is displayed in the standard orientation, then the display device can be positioned flexibly, but the level image does not correspond to the captured image orientation
Solution Approach 1:
The patent dynamically changes the orientation parameter of the level image based on the display screen's orientation angle. When the screen is positioned at an oblique angle, the level image is rotated by 90 degrees to maintain correspondence with the captured image. This parameter change allows the system to preserve information correspondence while accommodating flexible display positioning
Solution Approach 2:
The patent implements a dynamic adjustment mechanism where the level image orientation is automatically rotated based on the detected display screen orientation. This dynamic response ensures that the level image always corresponds to the captured image regardless of how the display device is positioned, maintaining information integrity while providing positioning flexibility
