Apparatus for analyzing depth of holographic image and analyzing method thereof

A method of analyzing a depth of a holographic image, the method comprising:

• acquiring a hologram using RGB brightness information and 3D stereoscopic information of an object;
• restoring a three-dimensional holographic image by irradiating the hologram with a light source;
• sensing a depth information image for each position in a holographic space in which the restored holographic image is displayed;
• restoring a three-dimensional image including a depth axis direction in real time using the sensed depth information image for each position;
• and
• comparing the restored 3D image including the depth axis direction with a depth of an original image corresponding to the object, and analyzing a depth quality based on the comparison result.
