Evaluation Device Guide Display for Consistent Imaging Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evaluation methods for work vehicle operators and vehicles face challenges in ensuring consistent imaging conditions, leading to subjective skill evaluations and potential misidentification of vehicle malfunctions, as the imaging position and safety of the person taking images are not consistently maintained.
Innovation Solution
An evaluation device with a first display control unit for displaying imaging data and a second display control unit that provides a guide display based on work vehicle data to determine the proper imaging position of the imaging device, ensuring safety and consistency in imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If imaging is performed manually without position guidance, then the person taking images can move freely, but the imaging position varies depending on timing or person, leading to inconsistent evaluation results
Solution Approach 1:
The patent introduces a guide display as an intermediary between the imager and the work vehicle. This guide display provides visual guidance (arrows, markers) to indicate the correct imaging position and orientation, allowing the imager to easily position themselves while ensuring consistent imaging conditions. The guide display acts as a mediator that translates the complex requirements of proper imaging positioning into simple visual cues.
Solution Approach 2:
The system provides real-time feedback to the imager through the guide display, which shows whether the imaging device is at the correct position and orientation. The guide display dynamically adjusts its guidance based on the imager's current position, providing continuous feedback to help them achieve and maintain the proper imaging position, thereby ensuring consistency without restricting movement.
2Measurement precision
If the imaging device is positioned close to the work vehicle for detailed imaging, then imaging quality improves, but the safety of the person taking images is compromised due to potential contact with moving parts
Solution Approach 1:
The system performs preliminary positioning guidance before actual imaging. The guide display shows the safe imaging position and orientation in advance, allowing the imager to position themselves at an optimal yet safe distance from the work vehicle. This preliminary guidance ensures that the imager achieves good imaging quality without needing to enter dangerous zones where moving parts could cause harm.
3Quantity of substance
If multiple imagers take images at different positions, then imaging coverage increases, but comparison and evaluation become difficult due to varying imaging conditions
Solution Approach 1:
The guide display serves multiple functions: it guides positioning, indicates orientation, and ensures consistent framing. By providing universal guidance that works for all imagers regardless of their background or the specific imaging task, the system ensures that all images are captured under standardized conditions. This multi-functional guide display enables multiple imagers to contribute to comprehensive coverage while maintaining evaluability of all images.

AI summary
An evaluation device includes a first display control unit that displays imaging data acquired by an imaging device on a display screen of a display device, and a second display control unit that displays on the display screen a guide display based on work vehicle data on a work vehicle imaged, to determine an imaging position of the imaging device.
