PURPOSE: A 3D depth camera using an infrared laser projection display is provided to irradiate an object with a laser beam of uniform light density, thereby forming a precise 3D image about the object. CONSTITUTION: One laser generator(100) transmits a laser beam of a specific wavelength band to an object(600). An optical scanner(200) changes the route of the laser beam. A photographing unit(300) includes a photographing module. The photographing module obtains depth information of a surface of the object by analog image information. The photographing module converts the analog image information into digital image information. A control unit(400) controls the laser generator and the optical scanner.
