A three-dimensional survey apparatus includes a collimating ranging unit, a scanner unit, and a control calculation portion. If there is a data-deficient part where three-dimensional data is not acquired among a measurement object when the scanner unit acquires point cloud data, the control calculation portion executes control to replenish the three-dimensional data related to the data-deficient part having been acquired by the collimating ranging unit to the point cloud data having been acquired by the scanner unit.

Apparatuses and methods for accurately applying an architectural layout to a surface. A calibration system includes a calibration rig having a plurality of vertical calibration legs assembled with a plurality of horizontal calibration legs and a laser that emits one or more beams of light onto a work surface to position the architectural layout relative to the calibration rig on the work surface. Calibration markers are positioned at intersections of the vertical and horizontal calibration legs for the laser to scan and confirm calibration accuracy of each of the calibration markers. The calibration markers calibrate the laser by using fixed, known points on the calibration grid that can be folded, collapsed, disassembled, and/or rolled for easy transport to other locations. The work surface can include obstacles and/or be uneven.

The presently disclosed subject matter is generally directed to an alignment device that can be used in a wide variety of situations, such as (but not limited to) the installation of pipes, conduits, and drainage fittings. The disclosed device comprises a housing defined by a central channel. A laser passes through the housing central channel and is configured to emit a beam of light in a straight or angled line, visible to the user. The laser beam can be used to accurately position pipes, drainage fittings, and the like. In some embodiments, the device includes one or more adaptors of various sizes that can releasably attach to the housing. The adaptor functions an adaptor, selected to fit a desired pipe size to allow for proper positioning of the device. Thus, in use, the housing and/or a portion of the adaptor can fit into an open end of a pipe such that the laser beam emits a beam of light indicating a projected location for a connecting pipe or conduit. In this way, the installation of a pipe is more accurate and efficient.
