Creating Plans, Then Models from Photos

Photo scaling with the intent of interpreting the original dimensions of an object is an application just made for a computer. Today’s tools provide a variety of methods for filling in information gaps. The photos above show the morphing of a simple grab shot into a head-on version of an obscured wall. The photo is stretched, color corrected, perspective corrected, and pulled into a reasonable representation of the head-on. Sizes are checked against known values, in this case, the mortar lines in the bricks, yielding dimensions sometimes accurate within less than an inch.
