Eyewear-UAV Video Synchronization for Low-Latency Stitching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear devices and unmanned aerial vehicles (UAVs) lack the capability to seamlessly synchronize video recordings from both perspectives, resulting in latency and inefficiencies in creating stitched video images.
Innovation Solution
The eyewear device is equipped with visible light cameras and an eye scanner, allowing it to synchronize video recordings with a UAV's camera by timestamping frames and compensating for latency, thereby creating synchronized stitched video images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video recordings from eyewear and UAV are captured separately without synchronization, then each device can independently record, but the stitching of video images becomes inefficient and experiences latency
Solution Approach 1:
The system performs preliminary actions by having both the eyewear device and UAV capture video frames simultaneously with synchronized timestamps. This pre-synchronization of data collection eliminates the need for complex post-processing alignment, thereby improving video stitching efficiency and reducing synchronization latency.
Solution Approach 2:
The system implements feedback mechanisms where the eyewear device receives and displays video frames from the UAV in real-time, and the UAV operator can adjust based on the synchronized first-person perspective. This feedback loop ensures continuous synchronization and allows for immediate corrections, maintaining high stitching efficiency and minimal latency throughout the operation.
2Adaptability or versatility
If the eyewear device integrates multiple functions (camera, eye scanner, display), then it provides comprehensive capabilities, but the device complexity increases
Solution Approach 1:
The eyewear device is designed with multi-functionality, integrating visible light cameras for video capture, eye scanners for gaze tracking, and see-through displays for real-time video presentation. This universal design allows a single device to perform multiple functions (recording, tracking, displaying), thereby providing comprehensive capabilities while managing complexity through functional integration rather than separate devices.
Solution Approach 2:
The system merges the eyewear device and UAV control functionality into an integrated system. The eyewear not only captures video but also serves as the control interface for the UAV, combining navigation, monitoring, and communication functions in one device. This merging reduces the need for separate control equipment and simplifies the overall system architecture despite the advanced capabilities.

AI summary
Eyewear configured to capture a video image of an object, and to control an unmanned aerial vehicle (UAV) to capture a video image of the object to produce stitched video images. The eyewear has an eyewear camera generating the eyewear video image, and the UAV has a UAV camera generating the UAV video image, wherein a processor timestamps frames of each of the video images. When the eyewear begins recording of the object, the eyewear controls the UAV camera to also begin recording the object. The stitched video images are synchronized to each other using the timestamps, wherein the stitched video images can be displayed on an eyewear display or a remote display. The processor compensates for any latency between when the eyewear begins recording and when the UAV begins recording.
