Beschreibung
Zusammenfassung:	An apparatus includes a tool body and a structured illumination device attached to the tool body, wherein the structured illumination device includes a light source and a light filter mask to generate a light pattern. The apparatus also includes a subsurface camera system attached to the tool body, wherein the subsurface camera system comprises a plurality of cameras. The apparatus also includes a processor and a machine-readable medium having program code executable by the processor to cause the apparatus to acquire an image of a feature using the subsurface camera system and determine a three-dimensional position of the feature based on the image, wherein the feature is illuminated by the light pattern.
