Fig. 3From: Stereoscopic facial imaging for pain assessment using rotational offset microlens arrays based structured illumination3D point cloud reconstruction obtained from the FRCM. a 3D face imaging without dot projection often results in incorrect stereo matching. Depth information acquisition fails or is obtained incorrectly in some parts of a non-textured surface. b Dot projection enhances the stereo matching results on non-textured surfacesBack to article page
