PROBLEM TO BE SOLVED: To provide a three-dimensional measuring device that can measure both of the overall shape and crack of a structure in real time, and can composite and display them on the same screen. SOLUTION: The three-dimensional measuring device includes a laser position detecting circuit 11 for calculating the coordinate of a laser emission line from an image signal from a CCD camera 7 in real time, a laser projector 20 for irradiating a tunnel 1 with laser slit light or spot light, an imaging device 30 for imaging light radiated to a surface of an object 1 by this laser projector 20, a transmitter 40 for forming a magnetic field vector in a predetermined area, an image processor 17 for converting the image data imaged by the CCD camera 7 so that a PC 12 easily processes it, a laser position detecting circuit 11 for detecting three-dimensional positional information and posture information from signals of a magnetometric sensor 4 and a magnetometric sensor 8, and the personal computer (PC) 12 for reproducing a three-dimensional image of the tunnel 1 based on data.
