Abstract

Since the service life of utility poles is limited, utility poles need to be regularly maintained. For this purpose, this paper proposes an algorithm developed to determine whether a utility pole needs to be discarded or how much it is cracked, using curvature information (curvature angle) thereof obtained from an image thereof. In particular, the curvature angle of a utility pole partially hidden by an obstacle is easily measured by setting environments (e.g., user pointer) of a program to extract edge information of the utility pole. An error between a theoretical value of a left or right curvature angle of a utility pole and a measured value thereof is 0.2°(degree), and when the utility pole is divided into 3 sections, i.e., an upper section, a middle section, and a lower section, corresponding errors are 0.42°, 0.28°, and 0.26°, respectively, and a mean error value is 0.32°. Even if this system is used in a real site, these error values are rarely influenced and therefore there may be little problem to employ the system.
