PROBLEM TO BE SOLVED: To provide a three-dimensional position measuring system and method with which it is possible to measure a measurement object efficiently with high accuracy even in a special environment.SOLUTION: The three-dimensional position measuring system comprises: first and second cameras 11A, 11B for imaging from mutually different directions; and a data processing device 20 for measuring the three-dimensional position of a measurement object by processing the images captured by the cameras 11A, 11B. The data processing device 20 includes: an image acquisition unit 21 for acquiring a reference lattice image and a measurement image; and an image analysis unit 22A which, with regard to a plurality of straight lines calculated using the reference lattice image and the measurement image, sets two straight lines ideal for the calculation of a measurement object point on the basis of the distance of a line segment linking straight lines together in shortest distance, finds a line segment that links the two straight lines together that have been set, calculates the three-dimensional coordinates of middle point of the line segment, and takes the three-dimensional coordinates as the three-dimensional position of the measurement object.SELECTED DRAWING: Figure 1
