摘要:
针对X射线机标定过程中的角点检测问题 ,该文设计了一套实用的处理方法。在采用了方形模板的基础上 ,该方法首先对原始图像进行分块 ,然后对分块后的部分分别进行边缘检测 ,在此基础上进行直线拟合并求交点 ,该交点即为所需的角点。实验结果表明 ,该方法对于X射线图像很适用 ,具有很强的鲁棒性。
Abstract:
This paper proposes a set of pract ical methods for corner detect ion used for X-ray device calibration. Based on the square pat tern adopted, the original image is divided into several small blocks and edge detection is conducted on each block. Line approx imat ion is carried out and cross point s of lines are solved. The cross points are just the corners needed. The ex perimental result s show the proposed method is fit for X-ray images and robust.
