Loading and unloading device, control device, control method, and storage medium

The invention relates to a loading and unloading device, a control device, a control method and a storage medium capable of improving conveying efficiency. According to one embodiment, a calculation system includes a detection unit, an integration unit, and a time calculation unit. The detection unit refers to a plurality of images obtained by capturing an object from mutually different angles, detects the object for each of the plurality of images, and calculates a provisional position of the object in a predetermined coordinate system. The integration unit calculates an integrated position of the object in the coordinate system using the plurality of calculated provisional positions. The time calculation unit refers to process information including information relating to a plurality of processes, and execution regions represented by the coordinate system for execution of each process, and calculates a required time for at least a portion of the plurality of processes on the basis of the integrated position
