[Non-invasive measurement of pressure ulcer simulated in plain model].
That is an quasi-experimental study that aims to improve and make portable an existing method for projecting light points to estimate geometrical properties of a cavity. A computer vision system was developed in order to process input images and calculate volume and depth of a cavity in a plain surface. An error of 1,51% for depth and -10,42% for volume occurred. So this is an adequate method for estimating geometrical properties of cavities with accuracy errors compatible with those errors described in the literature.
