Provided are a method and an apparatus for measuring a 3-dimensional (3D) position and an orientation of an object. The apparatus includes: a height measurement unit including a first light source and a first image sensor receiving light that is emitted from the first light source to the object and reflected from the object; a position measurement unit including a second light source, and a second image sensor receiving light that is emitted from the second light source to the object and reflected from the object; a tilt angle measurement unit including a third light source and a third image sensor receiving light that is emitted from the third light source to the object and reflected from the object; and a controlling unit selectively powering on or off the first, second, and third light sensors, and calculating a height variation, a position variation and tilt angles of the object by using images that are respectively formed on the first, second, and third image sensors.
