3D Scanner is growing industry due to remarkable interests in 3D printing nowadays. To make point cloud, 3D scanner can use many variety ways but generally uses structured light which is uniquely coded binary pattern and reconstructs 3D point cloud through stereo images. We first calibrate the camera, get rectified image, and apply boundary offset at the pre-processing. Using quaternary code on pixels, correspondence can be found roughly. For the purpose of obtaining high-precision point cloud, roughly matched correspondences are corrected with sub-pixel edge detection and phase interpolation. At the post-processing, remove the background and mismatched pixels. Result demonstrates the system has measurement area of 12 × 9㎝², with resolution about 0.06mm.
