Thereafter, the grapple device may obtain a target storage location of the target object in the storage system, and feed back the target storage location to the target client, so that the target client accesses the target storage location and obtains the target object. If the image capture device also receives the same image capture requests of other clients, the target storage position of the target object in the storage system can be directly obtained, and the target storage position is fed back to the target client, so that the target client accesses the target storage position and obtains the target object.
In the embodiment of the invention, when the target object is not stored in the storage system, the target access main body of the target camera device is determined, the target camera device is accessed and the image is captured, and the target object is obtained.
