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: A technique enables a surveying device to acquire a direction of a target by using as little extra hardware as possible. A method aims a laser scanner, as a surveying device, at a reflective prism that is a target. The method includes obtaining a photographic image of the laser scanner that is captured by a smartphone from the reflective prism side and determining a direction of the reflective prism as seen from the laser scanner on the basis of the photographic image. The method also includes rotating the laser scanner to make the laser scanner face the reflective prism straight on, on the basis of the direction of the reflective prism as seen from the laser scanner.

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.
