    Abstract: Provided is a surveying method that enables highly accurate surveying with use of a laser scanner, and, a target marker and a surveying system applicable to the surveying method, wherein the method includes marker placement in which at least one target marker, with at least a partial region formed of a retroreflective material, is placed; surveying in which a laser scanner is placed within a measurement area of the laser scanner at a position where the target marker was placed, and a surrounding space around the target marker is surveyed to acquire point cloud data; and marker identification in which a computer device detects at least one unsurveyable area in the point cloud data acquired in the surveying to create an error map, and identifies a position of placement of the target marker referring to the created error map.

    Abstract: A surveying system includes a distance measuring unit for performing the distance measurement based on the distance measuring light, an optical axis deflector configured to enable two-dimensionally deflecting the optical axis of the distance measuring light, a projecting direction detecting module for performing the angle measurement of the optical axis of the distance measuring light, and an arithmetic control module performs captures the pole by a scan pattern having a predetermined shape, acquires the point cloud data of at least two positions where the scan pattern crosses the pole, calculates an axis of the pole, calculates a direction vector, performs a linear scan along the direction vector, determines as a measuring point a point where an intersection of the optical axis of the distance measuring light and the direction vector coincides or substantially coincides with a measurement result, and calculates the three-dimensional coordinates of the measuring point.

    Abstract: Described is an adapter for attaching a measuring mark at a reference point. The adapter includes an adapter body to which a measuring mark is fixedly attachable or detachably attachable. At least a portion of the adapter body is formed into a plug that is adapted to a socket serving as a reference point such that it is insertable into the socket to establish a positive plug-in connection and is electrically insulated from the socket when inserted.

    Abstract: A survey system is provided which includes a surveying instrument capable of making distance and angle measurements of a target attached to a pole, and an eyewear device including an eye sensor configured to detect an eye motion, and an input unit for inputting a command corresponding to an eye motion detected by the eye sensor into the surveying instrument, and capable of displaying an image superimposed on a landscape. Measurement points are displayed on the eyewear device by being synchronized with and superimposed on a landscape of a survey site, and from the eyewear device worn by a worker, according to an eye motion, a command is input into the surveying instrument and distance and angle measurements of the target are made. A worker can perform a work while keeping a posture gripping the pole.

    Abstract: Automation of surveying operations is achieved. When surveying is performed by a surveying apparatus, acquisition of a surveying condition, acquisition of surveying data, acquisition of image data, and acquisition of environmental data are performed. These pieces of data are associated with each other and are stored as learning data. On the basis of this learning data, an AI-estimated model for estimating a surveying condition by using image data of a surveying target and environmental data of a surveying site, is generated.

    Abstract: Surface elements for the face of laser beam targets which more efficiently use the properties of light reflectance and absorption to aid a laser tool operator in accurately directing a laser's beam. The surface elements include beam alignment crosshairs and a background. A light-reflective material makes up or covers the background areas of the face not occupied by the beam alignment crosshairs, and allows the operator to better determine the direction and amount of lateral or vertical movement required for final alignment. The beam alignment crosshairs on the face of the target are formed from non-reflective, light-absorbing material that gives the beam an appearance of vanishing when precisely centered. Coupled with the light-reflective background, the light-absorbent crosshairs remedy multiple detriments from beam spread at greater distances, a weak beam, and a poorly discerned beam from bright or sunlit environments.
