Solution Overview
Problem
Existing aircraft inspection support devices face challenges in synchronizing the recording of videos from multiple imaging units, leading to out-of-synchronization issues when storing measurement and inspection target images, which hinders comparative analysis.
Innovation Solution
A measurement recording system and method that includes multiple imaging units and a recording device capable of measuring and correcting timing information to align the start times of videos captured by different units, allowing for synchronized playback without requiring a time code function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple videos are recorded simultaneously by multiple imaging units based on a recording instruction, then the recording operation is simplified and productivity is improved, but the videos become out-of-synchronization due to variations in processing time for each video
Solution Approach 1:
The system performs preliminary actions by measuring the timing information of each video before recording, and calculates the time axis shift in advance. This allows the synchronization correction to be applied during recording rather than requiring complex real-time coordination between multiple imaging units, thus maintaining high productivity while achieving precise time axis synchronization.
2Adaptability or versatility
If the start timing of videos is shifted due to processing time variations, then individual video recording flexibility is maintained, but the videos cannot be compared at the same timing during playback
Solution Approach 1:
The system employs feedback by measuring the actual timing information of each video and using this information to correct the time axis shift. The measured timing data feeds back into the recording process, allowing the system to automatically adjust and align the start timing of multiple videos during playback while maintaining the flexibility of individual recording operations.
3Measurement precision
If timing correction is applied to align start timing of multiple videos, then video comparison capability is improved, but additional processing steps are required
Solution Approach 1:
The system implements self-service by automatically measuring timing information and performing time axis correction without requiring manual intervention. The recording device autonomously calculates the time axis shift between multiple videos and applies the necessary correction, reducing the complexity of synchronization processing while achieving precise timing alignment for video comparison.

AI summary
A measurement recording system is configured to measure timing information for correcting out-of-synchronization of a time axis between a first captured video and a second captured video and correct the out-of-synchronization to align the start timing between the first captured video and the second captured video based on the measured timing information.
