た。Further, as shown in FIG. 4, two points P1 and P2 are provided.
When there is an obstacle 15 between them and the visibility between the two points P1 and P2 to be measured is poor, the two points P1 and P2 are set with the triangular point A located outside the two points P1 and P2 as a reference point. I was measuring the distance between them. That is, using the triangular point A whose position such as latitude and longitude is known in advance on the map as a reference point, the theodolides 11 and 12 are used to measure the distance from the two points P1 and P2 to the triangular point A, and the trigonometric method is used. 2 points P1 and P2
I was measuring the distance between them. In addition, for the triangular point A for which the position such as latitude and longitude is not known in advance on the map, after actually measuring the position of the triangular point A and determining the position of the triangular point A, the above two points The distance between P1 and P2 was measured.

長時間を要してしまう。However, in the above-described conventional two-point distance measuring device and two-point distance measuring method, as shown in FIG. 4, the obstacle 15 exists between the two points P1 and P2. If the line of sight between the two points P1 and P2 to be measured is poor, the distance between the two points P1 and P2 must be measured with the triangular point A, the position of which is determined in advance on the map, as the reference point. Therefore, in a place where such a triangular point A does not exist, the distance between the two points P1 and P2 cannot be measured by the trigonometric method. In addition, since the position of the triangular point A has to be actually measured for the triangular point A whose position is not known in advance on the map, the measurement work becomes complicated and the measurement takes a long time. .
