It is useful to develop procedures to scan wounds and reconstruct their 3D model with low\u2010cost techniques. We present a new procedure (Structure from Motion [SfM]\u20103DULC) that uses photographs for measuring nine wound variables. We also propose a new variant of ImageJ in which an orthophoto is used to measure the projected area (Ortho\u2010ImageJ). In addition, we compare the wound measurements made by dermatologists and non\u2010experts. A group of five experts in dermatology and five non\u2010specialists measured 33 leg wounds five times per procedure. Intra\u2010rater and inter\u2010rater reliability scores of SfM\u20103DULC were evaluated with the intraclass correlation coefficient (ICC 2,1). The accuracy of the two new procedures (SfM\u20103DULC and Ortho\u2010ImageJ) in the measurement of projected area was assessed by comparing their values with those obtained using ImageJ, with the Wilcoxon matched\u2010pairs signed rank test (<jats:italic>\u03b1<\/jats:italic>\u00a0=\u00a00.05). This test was also used to analyse the differences between the measurements made by dermatologists and non\u2010experts. All the variables measured by dermatologists using SfM\u20103DULC showed excellent scores of intra\u2010rater reliability (ICC\u2009&gt;\u20090.99) and inter\u2010rater reliability (ICC\u2009&gt;\u20090.98). No significant differences between the three procedures were found when comparing their projected area values. Significant differences between the measurements of dermatologists and non\u2010experts were found in most of the variables: circularity coefficient, perimeter, projected area, surface area, and reference surface area. The wound measurement procedure SfM\u20103DULC has an excellent reliability, is accurate for the measurement of projected area, and can be used by dermatologists for wound monitoring in everyday clinical practice.<\/jats:p>","DOI":"10.1111\/iwj.13595","type":"journal-article","created":{"date-parts":[[2021,5,18]],"date-time":"2021-05-18T11:47:06Z","timestamp":1621338426000},"page":"44-51","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["<scp>SfM\u20103DULC<\/scp>:
