Patent Images
1. A method of measuring and classifying in predetermined categories optically observable changes in skin and mucous membrane, comprising the steps of:
- 1. taking at at least one instant in time at least one digital image of a change in a skin suitable for determining the three-dimensional structure and color structure of the change and at least one digital reference image of at least the vicinity of the change;
2. computing surface measurement data comprising three-dimensional coordinates of the change and color values scaled to the reference image on the basis of the digital image and digital reference image;
3. carrying out a first process of classification on the basis of the surface measuring data;
4. carrying out a further process of classification differing from the first process by at least one modified algorithm;
5. Issuing the results of the first and second classification processes.

Abstract
A method and an apparatus for measuring and classifying skin anomalies by taking at least one digital image of the anomaly and a digital color reference image of healthy skin in the vicinity of the anomaly, computing surface measurement data including three-dimensional coordinates and color values scaled to the reference image of the anomaly and classifying the anomaly in predetermined categories on the basis of the surface measurement data.

17. An apparatus for measuring and classifying an optically observable change in a skin, comprising:
-
1. a measuring head comprising at least two calibrated cameras for generating at least two photogrammetrically evaluatable digital images of the change and a pattern projector for projecting a suitable pattern onto an area of the skin to be measured, at least one of the cameras being adapted for taking a color reference image of healthy skin in the vicinity of the change;
2. a first computer for preparing, processing and storing the digital images and for computing surface measurement comprising three-dimensional coordinates and associated color values scaled to the reference image; and
3. a second computer for carrying out a classification process on the basis of at least the surface measuring data computed by the first computer.
