| 摘 要： | 提出了一种矢量数据压缩方法:偏角限制道格拉斯———普克法。该方法以道格拉斯———普克法为基础,通过角度测定的方法,取出代表曲率变化的特征点,然后使用道格拉斯———普克法进行化简。在所需要化简的曲线曲率变化频繁的情况下,该方法可以规避其他压缩方法产生的压缩程度不够、丢失曲率变化特征点的情况。

| Abstract: | The thesis discusses a method of vector data compression: the Douglas-Peucker algorithm controlling by the goniometry. The method is based on the Douglas-Peucker algorithm. Its way of compressing the data can be divided into three processes: measuring the angles, deciding which points can represent the changing of curvature, dividing the data into several parts to perform the Douglas-Peucker algorithm. When the vector data needed to be compressed has many flections, using other compression techniques will bring into some failings, for example, decreasing the compression degree, losing the points that can show the changing of curvature, and so on. While using this method, lots of these failings could be avoided. |
