TOTAL STATION RE-SECTIONING USING TWO-DIMENSIONAL TARGETS

Two-dimensional targets, such as AprilTags, are used as control points. AprilTags can be used as cost effective alternatives to traditional prism targets without losing accuracy. AprilTags can be placed precisely around a construction site as “permanent” survey control points, like positioning reflector targets. A robotic total station, equipped with a camera sensor, can image the two-dimensional targets to efficiently resection itself.
