Embroidery Data Creation Using Feature Point Partitioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embroidery data creation methods often result in undesirable finished quality due to subtle differences between the arrangement of line segments from image data and the ideal embroidery pattern, leading to inconsistencies in the sewn embroidery pattern.
Innovation Solution
An embroidery data creation apparatus and program that specifies feature points and partitioned areas in both a model and target embroidery patterns, converting pattern information to ensure accurate reproduction of needle drop points and thread colors, thereby enhancing the finished quality of the sewn pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If embroidery data is created directly from image data using conventional methods, then the creation process is simple and quick, but the finished quality of the sewn embroidery pattern deteriorates due to subtle differences in line segment arrangement
Solution Approach 1:
The patent divides the embroidery pattern into multiple partitioned areas and further segments each area into triangular regions. By specifying feature points and creating partitioned areas, the system can process and adjust each segment independently, allowing for precise control of needle drop point distribution while maintaining an organized creation process
Solution Approach 2:
The patent performs preliminary actions by specifying feature points, creating partitioned areas, and converting pattern information before actual embroidery data generation. This preliminary processing ensures that the arrangement of line segments matches the ideal embroidery pattern, preventing quality issues before they occur
2Reliability
If the arrangement of line segments from image data is used directly, then the creation process is straightforward, but the distribution of needle drop points becomes unstable leading to thread instability
Solution Approach 1:
The patent applies local quality by specifying feature points at critical locations and creating partitioned areas that divide the pattern into manageable regions. Each triangular region within these partitioned areas can be independently adjusted to ensure proper needle drop point distribution, thereby ensuring thread stability in each local area while maintaining overall pattern integrity
Solution Approach 2:
The patent introduces partitioned areas and triangular regions as intermediary structures between the raw image data and the final embroidery data. These intermediaries allow for systematic adjustment and conversion of pattern information, ensuring that the needle drop point distribution is stable and reliable while the process remains manageable
Data Source
AI summary
An embroidery data creation apparatus includes a storage portion that stores pattern information for a first pattern, a first point specification portion that specifies first feature points, a first area specification portion that specifies first partitioned areas bounded by line segments linking the first feature points, an image acquisition portion that acquires a second image, a second point specification portion that specifies second feature points that correspond to the respective first feature points, a second area specification portion that specifies second partitioned areas bounded by line segments linking the second feature points, a conversion portion that, based on positional relationships between the first and second feature points, converts information of the pattern information that corresponds to the first partitioned areas into information that corresponds to the plurality of second partitioned areas, and a first creation portion that creates embroidery data for sewing the second pattern based on the information.
