1. A target, comprising:
- a background including a first intensity; and
a plurality of ovoid regions located on the background, wherein each of the plurality of ovoid regions includes a second intensity contrasting the first intensity;
wherein each of the plurality of ovoid regions is spaced at least a minimum distance from other of the plurality of ovoid regions;
wherein each of the plurality of ovoid regions includes a minor axis having at least the minimum distance;
wherein each of the plurality of ovoid regions is spaced at least the minimum distance from the outer edge of the background; and
wherein a width of a safety region substantially surrounding the background region is at least the minimum distance.

Abstract
We disclose a photogrammetry target that includes a background having a first color and a plurality of ovoid regions located on the background and having a second color contrasting the first color. We further disclose a method and system for detecting the target and processing image data captured from the target to discern therefrom at least one of a distance to the target, identification of the target, or pose of the target.
