基于Hough变换的水轮机特性曲线中坐标网格的检测与去除
首发时间:2009-01-14
摘要:通常工程曲线图为方便人工读取而设置了坐标网格,如模型水轮机的综合特性曲线,它是水轮机选型、设计的重要依据。论文基于Hough变换对水轮机综合特性曲线中坐标网格去除的研究。首先,利用Canny算法对图像进行边缘检测;然后,利用Hough变换检测出图像中的直线,分析实值标量的取值对检测结果的影响;最后,从原图像中减去提取的直线即为被去除坐标网格的图像,并提出算法改进的方向。

Coordinate Grid Detection and Elimination in Characteristic Curves of Turbine based on Hough transform
Abstract:Usually an engineering curve image has established with dense coordinate grid. It is convenient for people to read, such as the model Characteristic Curves of Turbine, it is an important basis of turbine shaping and designing. The article has based on Hough transform and made a research in coordinate grid elimination of Characteristic Curves of Turbine. First, imposed the Canny algorithm to check the marginal of image. Then, detected Straight-line in the image using the Hough transform, and made an analysis of real-value scalar to the result. Finally, the coordinate grid elimination in the image has been subtracted the straight-line from the original image, furthermore, it proposed an improved direction of the algorithm.
Keywords: Hough transform Coordinate grid Straight-line extraction Straight-line elimination
