We describe a process for extracting straight line segments from a digital image with high spatial accuracy and confidence. The line are then used to estimate projective transformations between natural, outdoor images with sparse features. The line estimates are more accurate than those obtained using a conventional scheme, and improve the estimation of projective transformations when used in conjunction with other features.
