The present invention relates to a triangular measuring system capable of effectively measuring a target point which cannot be directed measured because the target point is hidden by a building or a structure. According to a triangular measuring system prepared thereby, a distance (L1) and an azimuth (θ1) from a reference point (B) to a target point (A) which is hidden by a building or a structure can be measured by setting an additional auxiliary measuring point (C) besides the reference point (B) and the target point (A), installing an auxiliary measuring device (30) at the additional auxiliary measuring point (C), and performing measurement two times in a state of not moving a light wave measuring instrument (22). Therefore, the triangular measuring system of this present invention can perform measurement more simply and swiftly than the conventional triangular measuring system which requires two times of measurement while moving a target (10) and a measuring device. |
