Abstract
A method for positioning an object in a device is provided. The method may include: obtaining, using a capture device, a target image of the object on a table of the device; determining, in the target image, a current mock location associated with a target region of the object to be scanned or treated by the device; determining a distance between a current physical location of the target region and a target position based on the current mock location associated with the target region in the target image and a mapping relation; and/or causing the table to move such that the target region of the object is located at or in the vicinity of the target position, based on the distance.
Claims22
A method implemented on a computing device including a storage device and at least one processor for positioning an object in a device, the method comprising:
- obtaining, using a capture device, a target image of the object on a table of the device;
- determining, in the target image, a current mock location associated with a target region of the object to be scanned or treated by the device;
- determining a distance between a current physical location of the target region and a target position based on the current mock location associated with the target region in the target image and a mapping relation between an element in a calibration image captured using the capture device and a calibration distance that is between a physical location of the element when the calibration image is taken and the target position;
- and
- causing the table to move such that the target region of the object is located at or in the vicinity of the target position, based on the distance.

A system for calibrating a table of a device, comprising:
- at least one storage device storing a set of instructions;
- and
- at least one processor in communication with the storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to perform operations including:
- causing the table of the device to move to one or more physical locations;
- obtaining one or more images of the table at the one or more physical locations;
- and
- determining, based on the one or more physical locations and the one or more images, a mapping relation.
A system for positioning an object in a device, comprising:
- at least one storage device storing a set of instructions;
- and
- at least one processor in communication with the storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to perform operations including:
- obtaining, using a first capture device, a first image of a table of the device, the table being positioned at a first position such that a portion of the table is irradiated by a laser emitted from a laser source mounted on the device;
- determining, in the first image, a first target mock location of the portion of the table irradiated by the laser;
- obtaining, using the first capture device, a second image of the object on the table of the device, the table being positioned at a second position;
- identifying, in the second image, a target region of the object to be scanned or treated by the device based on a target preset in a protocol, the target corresponding to the target region of the object;
- determining, in the second image, a starting mock location of the target region of the object based on a scanning direction or treating direction preset in the protocol;
- determining a first difference between the first target mock location and the starting mock location in a first direction;
- and
- causing the table to be adjusted based on the first difference such that the target region of the object is located at or in a vicinity of a first target position.
