Abstract

Sweater pattern design plays a crucial role in practical production, determining whether the finished products can meet the requirements of customers. In addition, pattern-designing is also a vital link in the production of sweaters, affecting the development cycle and final quality of products. For this reason, this work proposed two different kinds of algorithms for sweater pattern design: synchronous filling algorithm and asynchronous filling algorithm, so as to realise the rapid design of sweater pattern in Computer-Aided Design (CAD) system by reducing the complex technique calculation. Firstly, the data structures of specifications and styles were established respectively based on the technological characteristics of sweaters, and then the algorithms for sweater pattern-generating were implemented by using C+ + programming technology. At last, the running time of each algorithm was tested to analyse the performances of the algorithms under the same filling scales and different filling scales, respectively. The results showed that the execution efficiency and stability of synchronous filling algorithm are better than that of asynchronous filling algorithm.

摘要

毛衣图案设计在实际生产中起着至关重要的作用，它决定了成品是否可以满足客户的要求。此外，图案设计也是毛衣生产中的重要环节，影响着产品的开发周期和最终质量。为此，本工作提出了两种不同的毛衣图案设计算法：同步填充算法和异步填充算法，从而通过减少复杂的技术计算来实现计算机辅助设计（CAD）系统中毛衣图案的快速设计。 。首先，根据毛衣的技术特点分别建立了规格和样式的数据结构，然后使用C ++编程技术实现了毛衣图案的生成算法。最后，测试了每种算法的运行时间，以分析算法在相同填充度和不同填充度下的性能。结果表明，同步填充算法的执行效率和稳定性优于异步填充算法。
