摘要： PROBLEM TO BE SOLVED: To stabilize and improve surveying accuracy by eliminating surveying error accumulation as well as dispersing errors.
SOLUTION: A method for surveying a position coordinate comprises a first step for surveying local coordinates of three reference points whose global coordinates are known beforehand by a surveying instrument 1 installed at any angle and any point, a second step for determining a rotational matrix and a translation vector used as coordinate conversion parameters based on a geometric relationship between the local coordinates and the global coordinates, a third step for determining by a least square method a corrected rotation matrix and a corrected translation vector which minimize a total sum of errors between coordinates obtained by converting the local coordinates of the reference points into global coordinates and the global coordinates of the reference points using the rotation matrix and the translation vector, and a fourth step for surveying a local coordinate of a surveying point by the surveying instrument and determining a global coordinate of the surveying point by converting the local coordinate into the global coordinate using the corrected rotation matrix and the corrected translation vector.
