    摘要: An object is to provide a three-dimensional data input apparatus that enables data currently required by the user to be easily extracted from the stored past three-dimensional data, shooting position data or shooting direction data. When the user provides the three-dimensional measuring device 1 with a measurement instruction, the portions operate through control by the central processing portion 17 to obtain the three-dimensional data SS and the two-dimensional image data SN of the object Q. The group of the three-dimensional data SS, the two-dimensional image data SN, the position data SP and the attitude data SA that are in the one-to-one correspondence with one another as described above are stored in the storage portion 18 every time the three-dimensional data of the object Q is measured. In a case where a fixed point observation of the object is repetitively performed by use of the three-dimensional measuring device 1, by extracting from the storage portion 18 three-dimensional data SSK and two-dimensional image data SNK obtained in the past and comparing them with the present three-dimensional data SSG and two-dimensional image data SNG, the change in the configuration of the object during that period can be found.
