摘要
通过分析像素梯度分布,提出基于梯度分布的低阈值调整算法.实验证明,改进后的边缘算法能有效地剔除孤立噪声,增强弱边缘信息,更好地为三坐标测量机提供定位信息.
This paper proposes a selLtuning algorithm for the low threshold value by analyzing the distribution of pixel gradient with the purpose of facilitating accurate positioning information for coordinate meas- uring machine. Experiments have prove that improved algorithm can remove isolated noise and enhance the weak edge information, which will offer better locating information to the three coordinate measuring machine.
