The invention discloses a total station non-leveling free observation station measurement method. The method comprises the following steps: S1, obtaining n common point coordinates of a total station during measurement in a leveling space rectangular coordinate system and a non-leveling space rectangular coordinate system; s2, carrying out gravity center processing on the n common point coordinates; s3, substituting the n common point coordinates after the barycentric processing into a Boolea-based space coordinate conversion model to obtain a non-leveling free measurement space coordinate conversion model; s4, calculating the minimum mean square estimation of the scale scaling factor k of the space coordinate transformation model of the non-leveling free measurement; ......; and s7, evaluating the precision of the non-leveling free measurement space coordinate conversion model. According to the non-leveling free observation station measurement three-dimensional coordinate conversion algorithm of the total station, the conversion precision is higher, iteration is not needed, calculation is simpler and more convenient, and the algorithm is suitable for carrying out three-dimensional coordinate conversion under the condition of any rotation angle.
