Abstract
One variation of a method for registering distance scan data includes: accessing a first distance scan recorded, at a first time, by a first depth sensor defining a first field of view; accessing a second distance scan recorded, at approximately the first time, by a second depth sensor defining a second field of view overlapping a portion of the first field of view; calculating a first set of lines represented by points in a first portion of the first distance scan overlapping a second portion of the second distance scan; calculating a second set of lines represented by points in the second portion of the second distance scan; calculating skew distances between each pair of corresponding lines in the first and second sets of lines; and calculating an alignment transformation that aligns the first distance scan and the second distance scan to minimize skew distances between corresponding pairs of lines.
