Paper Abstract

A parabola model is employed to fit high voltage power lines by using the remotely identified coordinates of the spacers and tower corners of power lines. The shortest distance between land surface height at a pixel and heights of power lines is defined as the warning index for indicating dangerousness of power lines. Three approaches on visualizing the warning index map are developed and implemented in the Airborne Multi-angle Power Line Inspection System. The visualization results show that the sliced color warning approach costs a relative low computing time, and can highlight the dangerous warning sites, the fused color warning approach integrates land surface properties and the warning levels, and the pseudo-color warning approach costs a relative high computing time and can be applied to visually interpret the dangerousness by gradual color change.
