Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a three-dimensional measuring method and a three-dimensional measuring system for measuring a three-dimensional shape of a target by measuring the distance to the target capable of easily performing geometric calibration processing.SOLUTION: The three-dimensional measuring method includes the steps of: measuring a distance to a group of a flat surface 12 at a position of which is given as a flat surface equation 72 (step 33); calculating an estimation distance 55 to the flat surface based on a calibration parameter 80 and the flat surface equation 72 (step 51); and updating the calibration parameter 80 based on a piece of difference information 56 between a measured distance 62 and the estimation distance 55 (step 52b).
