To easily prevent a height work, to easily rationalize a measuring work, and to easily connect this device with variety of evaluation system by highly precisely and quickly realizing target-less measurement.

This measuring device is a device for automatically measuring the three-dimensional coordinate values of plural measuring points set at an object 1 to be measured in a non-contact state and from a remote place. This device is provided with an image measuring equipment 6 for photographing each image including the measuring points from different two spots A and B, and for detecting each photographing direction, image storing equipment 7 for storing the plural images photographed by the image measuring equipment 6 and the photographing directions, and image analyzing equipment 9 for calculating directional vectors to the plural measuring points, based on the measuring point positions in the plural images stored in the image storing equipment 7, and the plural photographing directions stored in the image storing equipment, and for detecting the three-dimensional coordinate values of the plural measuring points as the cross spot of the vectors.
