| 2. | Best - fit line 最佳拟合线 |
| 3. | Best fit line 最优拟合线 |
| 4. | Steel flanged pipes and steel and cast iron flanged fittings lined with ptfe or pfa - technical specifications 带聚四氟乙烯或pfa衬里的钢制法兰管道和钢制与铸铁法 |
| 5. | The found edge points are then applied to the line fitting tool which fits an infinite length line to the points . the fitted line is hown in figure 6 将找到的边缘点应用于拟合工具,进而形成一条无限长的直线。拟合后的直线如图六所示。 |
| 6. | 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。 |
| 7. | Then a fast computing method is presented to estimate the curvature of edge points and the points at which curvature is less than some threshold are collected to fit lines 为提取直线边缘,使用改进的序列细化算法将边缘细化为单像素宽,而后用一种快速曲率估计方法估算边缘点的曲率,并保留估算值很小(约等于零)的点拟合直线。 |
| 8. | If a higher accuracy resolution is required , the distances of points to the fitting line can be taken as the judgment standard , and the data eliminated noise points by hough transform can be simulated by the least square method 当精度要求较高时,可将各拟合点到拟合直线的距离作为判别标准,对经霍夫变换剔除干扰点(或噪声)后的数据点再进行最小二乘法拟合。 |
| 9. | First , this method decide the skew angle of a business card image according to four border fitting lines of the business card , then a method based on block move is provided to correct image and black border is erased based on position of border near - line 该方法先检测出名片的四条边缘拟合直线,由四条边缘拟合直线的倾斜角度来确定名片图像倾斜角度,然后采用逐段整块搬移的方法来对图像进行倾斜校正,再根据边缘拟合直线位置去除黑边。 |
| 10. | By studying the characteristics of the eddy displacement sensor , it adopts the control method which include using the fitting line of sensor ' s output characteristic curve in certain block as control characteristic curve , and stipulating door limit district and a certain of backward overshoot , the stabilization of welding torch is gained under the certain track precision 摘要通过对涡流式位移传感器的特性研究,采用以传感器输出特性曲线在一定区间内的拟合直线作为控制特性曲线、设定规定门限区和一定反向调节量的控制方法,得到了在保证一定的跟踪精度条件下的焊枪稳定。 |
