1. A transport system comprising:
a transport path;
a storage portion disposed along the transport path, the storage portion storing an object to be transported that is to be used in machining a workpiece, the storage portion having a first reference shape within a range of a predetermined distance from one end of the storage portion in a direction parallel with the transport path, and a second reference shape within a range of a predetermined distance from the other end of the storage portion in the direction parallel with the transport path;
a plurality of machine tools;
a transport device that moves on the transport path, and transports the object to be transported stored in the storage portion to a machine tool that is a transport destination among the plurality of machine tools, the transport device being provided with a camera; and
a control unit that controls the transport device,
the control unit executing
a process of making the camera photograph the first reference shape by moving the transport device to a predetermined first position on the transport path, and acquiring a first image from the camera,
a process of making the camera photograph the second reference shape by moving the transport device to a predetermined second position on the transport path, and acquiring a second image from the camera, and
a process of correcting a control parameter to be used in transporting the object to be transported stored in the storage portion to the machine tool that is a transport destination on the basis of a position of the first reference shape in the first image and a position of the second reference shape in the second image.
