PROBLEM TO BE SOLVED: To superimpose the measurement point of a laser radar to a two-dimensional image with accuracy, even when the optical axis of the laser radar deviates by a large amount from that of a camera. SOLUTION: A marker 10 for three-dimensional measurement specifies a measurement target by superimposing a reflected intensity image 22, obtained from a laser radar device 20, with a two-dimensional image 32 obtained from the digital camera 30 for obtaining the distance information. The marker comprises a pattern 12, capable of identifying a specific position on the two-dimensional image in the digital camera; and a reflecting mirror 14 that is positioned at a specified position, having resolution that is lower than that of the laser radar device, and laser reflectance that is higher than those of other objects.
