Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inserting content into videos are difficult and time-consuming, as they require precise control over the placement and trajectory of the content within the video field of view.
Innovation Solution
A system that uses the trajectory information of the image capture device during video capture to determine the placement of objects within the video field of view, simplifying the insertion process by aligning the object with the device's trajectory and adjusting its size and position accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual control methods are used to place content in videos, then precise placement control is achieved, but the process becomes difficult and time-consuming
Solution Approach 1:
The system automatically determines content placement by analyzing the trajectory data from the image capture device itself. The trajectory component extracts position and orientation information directly from the device's recorded trajectory, eliminating the need for manual placement controls and significantly reducing insertion time while maintaining precision through automated calculation of placement parameters.
2Ease of operation
If automated placement based on trajectory is used, then user effort and time are reduced, but control precision over content placement is lost
Solution Approach 1:
The system uses feedback from the trajectory data to automatically adjust content placement parameters. The placement component receives trajectory information and calculates optimal placement positions and orientations based on the device's actual movement, providing automated precision that maintains control accuracy while reducing user effort through intelligent algorithmic determination of placement parameters.
3Manufacturing precision
If complex manual controls are provided for content insertion, then placement precision is maintained, but device complexity increases
Solution Approach 1:
The system extracts only the essential trajectory data (position and orientation) from the image capture device and uses this extracted information to determine content placement. By taking out only the necessary trajectory parameters and using them to automatically calculate placement, the system maintains precision without requiring complex manual control interfaces, thus reducing overall device complexity.
4Productivity
If trajectory information is utilized for automatic placement, then productivity is improved, but measurement and processing complexity increases
Solution Approach 1:
The system replaces manual mechanical control operations with automated computational processing of trajectory data. The trajectory component and placement component use algorithms to process trajectory information and determine content placement automatically, substituting complex manual measurement and control operations with computational methods that improve productivity while managing processing complexity through efficient data utilization.
