Assign a unique ID to each object manually, or scan a QR code, RFID tag, or NFC chip to enter the identifier automatically.
OrthoGraph checks whether the ID is already assigned to an object elsewhere in the project, which may indicate that the same object has been captured again. You can then move the existing object to the new location or keep it in its original location. In the latter case, either assign a different ID to the newly captured object or delete it.
