Semi-automatic mapping of electric poles using sfm technique

Abstract

The objective of this research is to proposed a semi-automatic method for mapping electric poles using the structure from motion technique or SFM. First, an epipolar geometry for each image pair is estimated. Then, the 3D structures are obtained using incremental SFM technique which will give us both 3D point cloud of the study area and camera parameters. Also, vertical 2D lines are extracted from the input images. These 2D lines and the 3D structures are then integreated for estimating the positions of electric pole in 3D space. Finally, these 3D electric poles are then geo-registered by estimating 3D rigid transformation from embeded coordinates in the input images.
