Abstract: On the basis of a measured shape, which is a three-dimensional shape of a subject measured by means of a measuring unit using an image captured when an image capturing unit is disposed in a first position and a first attitude, a movement control unit determines a second position and a second attitude for capturing an image of the subject again, and sends an instruction to a movement mechanism. The three-dimensional shape is represented by means of height information from a reference surface. The movement control unit extracts, from the measured shape, a deficient region having deficient height information, and determines the second position and the second attitude on the basis of the height information around the deficient region of the measured shape. The position and attitude of the image capturing unit can be determined in such a way as to make it easy to eliminate the effects of shadows.

Then, the control device outputs the determined control instruction to a robot device.
