linear segment meaning in English
线性部分
Examples
- First of all , according to the difficulty in setting the initial number of cluster , hough transform solves this problem by automatically specifying the number of linear segments
考虑到一般的聚类算法对于设置聚类中心的初值存在很多困难， hough变换通过自动获得数据的线性划分解决了此问题。 - Different to exiting methods , it first segments time series based on a series of perceptually important points , and then time series are converted into meaningful symbols sequences in terms of domain knowledge and the relative scope of each linear segment
不同于传统处理模式，该方法在序列分段上，采用了一种新颖的、基于重要点的时间序列线段化算法；在符号化过程中，采用基于相对斜率的局部符号化方法。 - Different to exiting methods , it first segments time series based on a series of perceptually important points , and then time series are converted into meaningful symbols sequences in terms of domain knowledge and the relative scope of each linear segment
不同于传统处理模式，该方法在序列分段上，采用了一种新颖的、基于重要点的时间序列线段化算法；再符号化过程中，采用基于相对斜率的局部符号化方法。 - The methodology adopted by most existing cam / cnc systems , which uses huge amount of linear segments to approach the original shape and make linear interposition increases the cost of memory size and communication work of the cnc system tremendously . a new approach based on cubic polynomial and b spline interposition to rebuild the cam generated tool path under real time condition is presented in the paper . applications on cnc machine tools showed that the presented approach improves the machining accuracy and increases the cutting speed significantly
目前大多数cam / cnc系统采用大量小直线段逼近原始曲线和直线插补的做法，只能获得零阶连续的走刀轨迹，逼近精度低，不能保证高速加工运动的平稳性，因而加工精度、光洁度和加工速度都难以提高；由小直线段构成的nc代码数据量庞大，也增加了数控系统在内存容量和数据传输方面的成本。
