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.

One variation of a method for autonomous navigation includes, at an autonomous vehicle: recording a first image via a first sensor and a second image via a second sensor during a scan cycle; calculating a first field of view of the first sensor and a second field of view of the second sensor during the scan cycle based on surfaces represented in the first and second images; characterizing a spatial redundancy between the first sensor and the second sensor based on an overlap of the first and second fields of view; in response to the spatial redundancy remaining below a threshold redundancy, disabling execution of a first navigational action&#x2014;action informed by presence of external objects within a first region of a scene around the autonomous vehicle spanning the overlap&#x2014;by the autonomous vehicle; and autonomously executing navigational actions, excluding the first navigational action, following the scan cycle.
