METHOD FOR POSITIONING CENTRIFUGE TUBE RACK, DEVICE, AND COMPUTER READABLE STORAGE MEDIUM

The present application relates to a method for positioning a centrifuge tube rack, a device, and a computer readable storage medium, for use in improving the practicability and convenience of position identification of the centrifugal tube rack. The method comprises: photographing a centrifugal cavity of a centrifugal machine by means of a visual device to acquire an image in a certain range with the center of a centrifugal machine rotor as the circle center; matching feature points used for positioning the centrifuge tube rack in the image; acquiring coordinates of the feature points in a rotor coordinate system which is a coordinate system where the centrifugal machine rotor is located; and calculating coordinates of the center of the centrifuge tube rack in the rotor coordinate system according to the coordinates of the feature points in the rotor coordinate system. The technical solution of the present application makes the positioning of the centrifugal tube rack not influenced by the type of the centri
