Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The low fluency and playback quality of video data collected by unmanned aerial vehicles (UAVs) due to fluctuations in flight speed and maneuvering, leading to an unsatisfactory user experience.

Innovation Solution

A video processing method that determines adjustment speeds corresponding to flight speeds and calculates playback rates to ensure smooth playback of video data collected by UAVs, using algorithms and user inputs to set adjustment speeds based on flight parameters and user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If video data is collected by UAVs during flight, then video data is obtained, but playback smoothness deteriorates due to flight speed fluctuations

Engineering Contradiction:

Improvevideo data collectionVSAvoidplayback smoothness

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The patent applies dynamics by making the playback rate adjustable and variable rather than fixed. The system allows dynamic adjustment of playback rate based on flight speed variations, enabling the playback to adapt to changing flight conditions and maintain smoothness despite speed fluctuations during data collection

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the playback rate parameter to resolve the contradiction. By modifying the playback rate parameter according to flight speed measurements, the system maintains playback smoothness while preserving the完整性 of collected video data, transforming a static playback parameter into a dynamic one that responds to flight conditions

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If flight speed varies during UAV operation, then UAV can perform diverse maneuvers, but video playback quality deteriorates

Engineering Contradiction:

Improveflight maneuver capabilityVSAvoidplayback quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements feedback by measuring actual flight speed and using this information to adjust playback rate. The system creates a closed-loop control where flight speed measurements feed back to the playback rate adjustment mechanism, ensuring playback quality remains reliable despite varied flight maneuvers and speed changes

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system makes playback rate dynamic by linking it to flight speed variations. This dynamic adjustment allows the playback to adapt to different flight maneuvers while maintaining quality, transforming the playback process from a static operation to one that responds to real-time flight conditions

Inventive Principle:

Principle #15Dynamics

AI summary

A video processing device may comprise at least one memory and at least one processor. The at least one memory may store executable instruction; and when executing the executable instruction stored in the at least one memory, the at least one processor may be configured to acquire video image data collected by an image acquirer of a flying object and a flight speed set of the flying object; determine at least one adjustment speed; determine a playback rate of the video image data based on the flight speed set and the at least one adjustment speed; and play the video image data at the playback rate.
