Methods and devices for use in surveying operations are provided. A device is provided for selectively connecting to surveying equipment, such as a surveying pole, and is adapted for accurately adjusting a reference point in at least two axes. The device is adapted to work in conjunction with additional surveying equipment, such as theodolites and transits as well as one or more central processing units for analyzing, storing, and providing data.

A preferred system and method for projecting a business information model at a construction site includes a network, a system administrator connected to the network, a database connected to the system administrator, a set of registration markers positioned in the construction site, and a set of user devices connected to the network. The system includes a hard hat, a set of headsets mounted to the hard hat, a set of display units movably connected to the set of headsets, a set of cameras connected to the set of headsets, and a wearable computer connected to the set of headsets and to the network. The cameras capture an image of the set of registration markers. A position of the user device is determined from the image and an orientation is determined from motion sensors. A BIM is downloaded and projected to a removable visor based on the position and orientation.

A preferred system and method for displaying a set of indicator coordinates in relation to a building information model includes a system administrator, a registration base and a headset unit. The system includes a headset including a display and a registration base for initial placement of the headset. The headset further includes a set of stereo cameras. The cameras capture an image of the construction site and overlay an image which includes the indicator coordinates. A position of the headset is determined relative to the registration base from motion sensors. A set of indicator coordinates is downloaded and projected to the display based on the position and orientation of the headset.

A measurement and installation data indicating apparatus including a distance image sensor that obtains distance image data in a predetermined range, a projector that projects an image on a projection plane in a predetermined range, an inclination data obtaining part that obtains inclination data on a detection optical axis and a projection optical axis relative to a vertical direction, a positional data obtaining part that obtains coordinate data on a present position and a target position, and a terminal controller that generates, based on the coordinate data, a target information image related to the target position and seen from the present position. The terminal controller corrects the target information image to fit to a shape of the projection plane based on the distance image data and the inclination data, and projects the corrected target information image by the projector.

Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component configured to transmit one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.
