Abstract: This paper presents a 3D reconstruction (by 3D-snake) of the longitudinal axis of an electrical arc (discharge) in evolution based on stereo pairs of images. The accuracy of such tracking depends strongly on the halting of the iterative relaxation process that adjusts the 3D-snake. The key aspect to make such decision is detecting when each projection of the 3D-snake matches special features in the pair of images. For this sake, this paper proposes a simple and effective strategy based on the projection matrices of the cameras and tables named Maps of Distances (MDs) which are obtained by image processing.
