A carrier for carrying an object includes a fork that is vertically movable to carry the object and that is able to be inserted into an opening of a flat portion of the object, a sensor that obtains actual measured values at a plurality of points on the flat portion of the object, and an object state identification device that identifies, based on the actual measured values, an object state including at least one of a position and a posture of the object with respect to the sensor.

Object state identification method, object state identification apparatus, and carrier

An object state identification method of identifying a position and a posture of an object by obtaining actual measured values at a plurality of points on a flat portion including an opening on a surface of the object by a sensor includes generating a model value group that is a set of model values indicating the positions of a plurality of points present on surfaces of a corner model, calculating a model feature value based on at least one model value included in the model value group, calculating an actual feature value by the same method used to calculate the model feature value, extracting a corresponding point value indicating a position of an edge of the opening based on the actual feature value that matches the model feature value, and identifying the position and posture of the object based on the corresponding point value.
