A flowchart of the proposed method. The method consists of three phases: 3D reconstruction, UV unwrapping and 2D calculation. (1) In the first phase, multiple images of one object are captured by smart-phone, the features of them are extracted and matched through SIFT. Then the 3D model of the object is reconstructed based on SFM, and goes through the process of sparse & dense reconstruction and networking. (2) In the second phase, the UV of the 3D model is unwrapped to a 2D image based on LSCM. (3) In the lase phase, the wound area on the 2D image is extracted and calculated
