Fig. 13From: Wound area measurement with 3D transformation and smartphone imagesSchematic diagram of SFM. A target point P1(x,y,z) in the space passes through the horizontal, vertical, and rotational motions to point P2(x∣,y∣,z∣), point (X,Y) and, (X∣,Y∣) respectively represent the imaging point in a 2D plan for P1(x,y,z) and P2(x∣,y∣,z∣)Back to article page
