Mobile Terminal Feedback for Simpler Camera Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera calibration on drones requires a monitor and personal computer for operation, making it cumbersome and difficult for users to determine if imaging is appropriately performed.
Innovation Solution
An information processing device generates triggers for displaying a pattern on a mobile terminal and providing feedback on the mobile terminal to ensure appropriate imaging, allowing calibration without the need for additional equipment and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional camera calibration method using monitor and PC is used, then calibration can be performed, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the calibration pattern display function and the feedback display function into a single mobile terminal device. The mobile terminal both displays the calibration pattern and provides real-time feedback on imaging quality, eliminating the need for separate monitor and PC equipment while simplifying the calibration process.
Solution Approach 2:
The mobile terminal serves multiple functions: it displays the calibration pattern, captures images through the camera, evaluates imaging quality, and provides feedback to the user. This multi-functional approach replaces the conventional setup requiring separate monitor and PC, reducing overall system complexity.
2Ease of operation
If conventional camera calibration method is used, then calibration can be performed, but ease of operation worsens due to user burden
Solution Approach 1:
The system performs self-evaluation of imaging quality by automatically analyzing captured images against calibration criteria. The mobile terminal autonomously determines whether imaging is appropriate and provides feedback without requiring manual assessment by the user, reducing operational complexity.
Solution Approach 2:
The patent implements real-time feedback mechanism where the mobile terminal displays feedback information to the user based on whether appropriate imaging is achieved. This feedback loop guides the user through the calibration process automatically, simplifying operation without requiring complex manual procedures.
3Loss of information
If conventional camera calibration method is used, then calibration can be performed, but information loss occurs regarding imaging quality
Solution Approach 1:
The mobile terminal continuously monitors captured images and provides real-time feedback information to the user about imaging quality. This feedback mechanism ensures that no information about imaging appropriateness is lost, as the system automatically evaluates and communicates the results.
Solution Approach 2:
The mobile terminal acts as an intermediary between the camera and the user, automatically analyzing imaging quality and translating technical calibration information into user-friendly feedback. This intermediary function prevents information loss by systematically evaluating and communicating imaging status.
