Abstract

See full text

A remote wound assessment method and apparatus includes forming an oblique image of a wound and a target plate containing a rectangle and placed near the wound. Using a novel method of determining vanishing points where photographic images of parallel lines on the target object intersect, coordinate transformations are calculated which map the oblique image of the rectangle into a normal image thereof. Using the same coordinate transformations, an oblique image of a wound adjacent to the target plate is mapped into a normal view thereof, allowing precise measurement of wound features. By forming two separate images of a wound and target plate at two different oblique inclinations, three dimensional features of a wound may be measured.
