Abstract

The present disclosure proposes a detachable second apparatus coupled to a first apparatus that determines a first three-dimensional shape of an object and configured to determine an angle of an upper surface of the object. The second apparatus includes a first light source configured to sequentially irradiate first pattern lights having one phase range, a beam splitter and lenses configured to change optical paths of the first pattern lights so that a beam of light corresponding to a respective phase of the phase range spreads, and arrives at each point of a partial region of the upper surface of the object, a communication interface, and a first processor configured to obtain first information on first reflected lights generated by reflecting the first pattern lights from the partial region and determine the angle of the upper surface with respect to the reference plane based on the first information.
