Abstract: A calibration method of an optical coherence tomography (OCT) device and a camera using the same target includes irradiating a shape measurement light to a calibration target, obtaining a surface shape image thereof by detecting light reflected by a surface of the calibration target using a shape measurement camera, and calibrating the surface shape image according to an actual shape of the calibration target; obtaining surface and internal three-dimensional images of the calibration target by scanning with a layer measurement light using the OCT measurement unit, extracting a surface shape image of the calibration target from the three-dimensional images, and calibrating the surface shape image according to the actual surface shape of the calibration target; and matching a calibration image obtained by the shape measurement camera and a surface calibration image obtained by the OCT measurement unit to be displayed at the same spatial coordinates.
