CONSTRUCTION MEMBER MEASURING METHOD AND MEASUREMENT SYSTEM FOR THE METHOD

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 (2) including a distance-measuring unit (21) configured to perform a non-prism measurement of a distance and an angle to a measurement point, a measurement system (1) performs the non-prism measurement along a three-dimensional measurement line (ML) formed by connecting three-dimensional coordinates of two or more designated points (T1, T2) 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 (ML), 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 (22).
