Abstract: Provided is construction management so that a final form of a structure is as designed. In the construction management, reading a design model of a structure from a design database, designing an initial construction model so that final form physical simulation results obtained by performing a physical simulation match the design model, extracting a construction completed part model, a calculating step partial physical simulation results obtained by performing the physical simulation for the construction completed part model, obtaining a measurement model from a measurement database, a calculating step an actual object difference by comparing the partial physical simulation results with the measurement model, and instructing construction details of a part to be constructed next and/or later of the initial construction model or an actual object of the structure based on the actual object difference, are performed.

Abstract: To efficiently and accurately detect coordinates positions of a measurement object formed in a linear shape regardless of a distance from a measurement light emitting unit. The provided survey system includes: a distance measuring unit; a deflecting unit for deflecting a direction of measurement light with respect to a reference optical axis and for scanning with the measurement light with respect to a prescribed center in a circumferential direction; and a calculation control unit which controls the distance measuring unit and the deflecting unit, wherein the calculation control unit detects coordinates of intersection points of a measurement object formed in a linear shape and a scan trajectory of the measurement light, and controls a deflection operation of the deflecting unit so that intervals of the intersection points adjacent to each other are constant intervals on the measurement object.

Abstract: Provided are a measuring method and a measurement system which enable scanning of only a member as a construction management target, and promptly obtain measurement results on-site. In order to achieve the above-described object, by using a measuring device including a distance-measuring unit configured to perform a non-prism measurement of a distance and an angle to a measurement point, a measurement system performs the non-prism measurement along a three-dimensional measurement line formed by connecting three-dimensional coordinates of two or more designated points designated on a three-dimensional space with respect to a measuring target by a straight line, and from three-dimensional coordinates of measurement points measured near the three-dimensional measurement line, calculates measurement results of a member spacing and/or a member thickness of the measuring target, and displays the measurement results on a display unit.

Abstract: A measurement apparatus is provided that includes a distance measuring unit, a deflecting unit, and a calculation control unit which controls the distance measuring unit and the deflecting unit. The calculation control unit detects coordinates of a pair of intersection points of the object to be measured and a scan trajectory with the measurement light on the basis of a distance measurement result by the distance measuring unit and the direction of emission deflected by the deflecting unit. The calculation control unit controls a deflection operation of the deflecting unit so as to change the direction of emission on the basis of the coordinates of the pair of intersection points such that the scan trajectory with the measurement light and the object to be measured intersect with each other.

Abstract: A technique is provided to more easily measure a distance of a target from a ground surface or a ceiling surface. A surveying device has a laser scanner part and a total station in a unitary manner. The surveying device includes a TS functional part, a laser scanner part, and a distance calculator. The TS functional part positions a reflective prism by using laser light. The laser scanner part performs laser scanning of a ground surface along a vertical plane containing the reflective prism and an optical axis for the laser positioning to obtain a laser scanned point cloud. The distance calculator calculates a distance between the ground surface and the reflective prism on the basis of one or multiple points, which are extracted from the laser scanned point cloud and in proximity to a straight line connecting the reflective prism and a specific plane.

Abstract: A technique for more reliably capturing a lost unmanned aerial vehicle in tracking the unmanned aerial vehicle by a surveying device is provided. A UAV search controlling part configured to be used in a search for an unmanned aerial vehicle that flies along a predetermined flight path includes an estimating part and a search controlling part. The estimating part estimates, on the basis of location data of a surveying device that surveys a location of the unmanned aerial vehicle by using laser light and on the basis of the predetermined flight path, a direction of the unmanned aerial vehicle as seen from the surveying device at a specific time. The search controlling part controls to allow the surveying device to search for the unmanned aerial vehicle, on the basis of the estimated direction.
