PhotoSketch Plugin for Google SketchUp: Floor Alignment Using Vertical-Line Correspondence

This tutorial shows how to perform floor alignment by drawing line segments on the vertical edges of façades or windows among two photos in the path. In many scene photos, it is often easier to find vertical line segments than finding corresponding points on a horizontal plane. The goal of this tool is to draw vertical line segments on a photo and match these segments across photos in the sequence. The user is free to start from any photo in the sequence. Technically, the user only needs to draw one set of line correspondences to align the floor. However, drawing more than one pair of line correspondences is recommended to distribute the floor alignment error among all photos in the scene. See http://www.brainstormllc.com/ for more details.
