绣花问题是连续型的填充，在不同区域的缝制过程中，缝针不能提针，因此不能用一般的离散型区 域填充方法处理。本文运用几何计算和图论理论提出了一个绣花缝针轨迹自动生成算法：先对轮廓走向进行 定义，通过轮廓铅垂方向的局部极值点的分割线将图案从上向下进行分割，采用交点的特征值比较彻底的解 决了分割时的重点问题，将图案区域准确的划分成缝针能一次完成的若干个节点。在此基础上根据节点的邻 接关系建立节点的邻接“图”，通过图论中半哈密尔顿路径或深度遍历方法找到节点的遍历（缝制）序列和每 个节点的缝制方向，最后可对设定的起点、终点和缝针间隔的条件自动提供缝针的走向轨迹。(In the process of embroidering, needle can not hang up for changing to a different area. Therefore, Embroider problem could be abstract as a continuous area-filling work. Considering disperse area-filling methods can not process this problem well. Based on geometry computing and graph theory, an algorithm of finding path of embroidering needle are proposed in this paper. First, outline orientations are defined, and finding all local extreme points of inner outline on their gravitational orientation to build sectioning lines so as to divide the picture. By using intersection point character the overlap point problem was solved perfectly. Therefore, the picture is divided into some nodes which can be finished alone. Then, based on connections of these nodes, an adjacency graph of nodes was built. Using half-Hamilton path or depth-first search method, both embroidering sequence and direction of these nodes could be got from the graph. Finally, from a defined start-point, end-point)

说明：  这本书最初是为北京亚嵌教育研究中心的嵌入式Linux系统工程师就业班课程量身定做的教材之一。该课程是为期四个月的全日制职业培训，要求学员毕业时具备非常Solid的C编程能力，能熟练地使用Linux系统，同时对计算机体系结构与指令集、操作系统原理和设备驱动程序都有较深入的了解。(This book was originally one of the textbooks tailored for the Embedded Linux System Engineers course at the Beijing Institute of Embedded Education Research. The course is for a period of four Full-time vocational training for the month, requiring students to have very solid C programming skills when they graduate, skilled use of Linux systems, and computer architectureHave a deeper understanding of the instruction set, operating system principles and device drivers.)
