Abstract
The efficiency of work for identifying reference points included in photographed images is improved. A survey data processing device includes a data receiving unitthat receives data of two still images, an operation information receiving unitthat receives a selection of reference points among multiple reference points which are included in both of the two still images and have known location information, an exterior orientation parameter calculating unitthat calculates exterior orientation parameters of a camera, a coordinate integrating unitfor obtaining an integrated coordinate system for describing both the locations of an unselected reference point and the camera, a back-projected image generating unitfor generating a back-projected image by back-projecting the unselected reference point in the integrated coordinate system, and a target position estimating unitthat estimates a position of the unselected reference point in a still image.
