A Novel Method for Detecting Encroachments on Transmission Lines Based on Visual Attention

The concept of "inspection robot" is born in the strong & smart grid. By studying on the mechanism of human visual attention, this paper presents a method to detect the encroachments on transmission Lines from the perspective of the saLiency-based visual attention system. There are conspicuous diffidence between the encroachments and transmission Lines and it is easy for human to distinguish the encroachments from the transmission Lines because the encroachments were always the saLient objects in the view, consequently, it is a reasonable way to detect the encroachments based on the mechanism of visual attention. The experiment results show that this method can effectively detect and locate different types of encroachments in different natural environments.
