An apparatus for measuring a gap between a mask and a substrate and a method thereof are provided. The apparatus includes a laser displacement sensor, which is placed on a mask and a substrate spaced apart from each other by a predetermined gap, emits laser beams while moving onto the mask and the substrate in a horizontal direction and measures a gap between the mask and the substrate using a variation in distance values measured based on light-receiving positions of the laser beams that are reflected from the mask and the substrate and return to their original positions, respectively.

Provided are an apparatus and method for reconstructing 3D face avatar. The apparatus includes a face detection unit, a stereo matching unit, a bilateral filter, and a texture mapping unit. The face detection unit receives a left image and right image of a user, and detects a face image of the user from the left and right images using a face detection algorithm. The stereo matching unit receives the left and right images of the user, and creates a depth map image from the left and right images through a stereo matching operation which uses disparity between the left and right images. The bilateral filter abstracts the detected face image through a bilateral filtering operation. The texture mapping unit texture-maps the abstracted face image on the created depth map image to reconstruct a 3D avatar.
