摘要：

In order to obtain the average surface roughness R-a of the long-term operating conductors in service, the features of 2-D surface morphologies were investigated based on the gray value matrix G. The neighborhood averaging method was utilized in obtaining G. In a wide range of R-a, a linear relationship was discovered between the variance F and R-a Therefore, R-a could be obtained based on the images from the camera and G without the need to dismantle the conductors in service, and it is more time saving and economical for the measurements.
