Abstract: A control apparatus capable of efficiently detecting a target object even when the target object is shielded by other objects is provided. An object recognition unit 114 recognizes a target object 80 present in a 3D environment 4 by using measurement data acquired from a sensor 12. An information generation unit 116 generates 3D environmental information by integrating a plurality of measurement data. A position determination unit 120 determines an optimal position of the sensor 12 for performing the next measurement. A sensor control unit 140 moves the sensor 12 to the determined optimal position. The position determination unit 120 determines, by using the 3D environmental information, a position of the sensor 12 where the sensor 12 can take an image in which a size of an area shielded by at least one first object is larger as the optimal position.
