Eyewear-UAV Video Synchronization for Stitched Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear devices and UAVs lack the capability to seamlessly synchronize video recordings from both devices, resulting in latency and inefficiencies in creating stitched video images.
Innovation Solution
The eyewear device is equipped with an eyewear camera and a processor that timestamps frames of both the eyewear video and the UAV video, allowing the eyewear to control the UAV camera to start recording simultaneously, and compensating for any latency to synchronize the frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video recording is initiated separately on eyewear device and UAV, then each device can independently capture footage, but latency and desynchronization occur between the two video streams
Solution Approach 1:
The system performs preliminary actions by having the eyewear device send a recording start instruction to the UAV before actual recording begins. The UAV receives and prepares to record upon receiving this instruction, ensuring both devices are synchronized from the outset. This preliminary coordination eliminates latency and desynchronization issues that would occur with independent recording initiation.
2Productivity
If separate recording systems are used for eyewear and UAV, then device independence is maintained, but seamless stitched video creation becomes difficult
Solution Approach 1:
The eyewear device acts as an intermediary that coordinates the recording process between itself and the UAV. It sends recording control instructions to the UAV and receives video data, serving as the central controller for synchronized recording. This intermediary role simplifies the overall system architecture by establishing a clear command-and-control relationship, making stitched video creation more efficient without excessive complexity.

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.
