直线拟合 meaning in English
fitting a straight line
Examples
- The attempts using k - l transform to fit line and introducing a new expression of the ellipse parameters improve the robustness and decrease the complexities of the algorithms
在吸取有关文献的基础上采用k - l变换进行直线拟合，提高了拟合鲁棒性和精度。 - Based on the results of the edge anchor , several segments of the height data are selected and linear polynomial fitting are done using least square approximant on these segments separately
根据台阶边缘检测结果,选取部分采样点数据,用最小二乘法进行直线拟合。 - It analyses and studies the operating method in image processing area , including image division , image filter , picking up edge point , drawing up line and getting the distance of parallel lines
分析并研究了可用于指针图像处理的图像分割、图像滤波、边缘点提取、直线拟合、平行直线求距等运算方法。 - In chapter 4 , mathematical theory about related coefficient and fitting of straighten anti - curve line is introduced at the beginning of this chapter , then how to program to calculate related coefficient is introduced including discussing the appearance of straighten anti - curve line in bitmap , searching the ends of straighten anti - curve line , calculating the angle bitmap should be turned , calculating related coefficient after bitmap has been turned
第4章首先介绍了有关相关系数以及直线拟合的数学理论，然后阐述了求解逆直线相关系数的编程思路，其中包括对逆直线在位图中摆放方式的分类讨论、逆直线端点的搜索、求解旋转角度、旋转后求解相关系数等几个环节。 - It employs a series of processing methods . for example , it employs different method of threshold according to illumination and the characteristic of the dial plate ; employs the method of mathematic form filtering according to the thought of the line is the most important in image ; employs the method of beeline matching according to the characteristic of the line
此系统利用了图像处理的基本思想，采用了一系列的处理方法，如根据照度及表盘特点采用了不同的二值化方法；根据图像中线条最重要的思想对图像的滤波采用了数学形态滤波方法；根据线条特点提出了利用直线拟合的方法等。
