Abstract This paper presents a computer vision application for the detection of a tie-wire in a live-line maintenance operation for the replacement of insulators. The tie-wire is wrapped around the electrical conductor and must be unwrapped by a special tool fixed to the end effector of a manipulator. The computer vision algorithm uses pyramidal image reduction, edge image analysis, and inverse perspective projection to count the number of tie-wire turns around the conductor and compute the three-dimensional coordinates of each turn (or the distance between adjacent turns).
