Microprocessor-supported method for measuring e.g. skin wound in skin area of human patient during in-vivo process, involves determining boundary curve based on determined co-ordinates, and deriving parameter representing defect from curve

摘要

The method involves scanning a surface section (2) containing a skin area defect (1) with a three dimensional (3D)-scanner (3) for producing 3D co-ordinates of a set of surface dots (4) of the surface section. A closed 3D boundary curve (6) describing a curve of an edge (5) of the defect is determined based on the determined 3D co-ordinates. A geometric parameter representing the defect is derived from the 3D boundary curve. Color or contrast values (7) are determined from the 3D co-ordinates, and a portion of the 3D boundary curve is interactively determined from the 3D co-ordinates. An independent claim is also included for a device for measuring a defect in a skin area.
