1. A method of assessing a feature on a patient's skin surface, the method comprising:
a) guiding a user to position a first camera and a second camera relative to the patient's skin surface, wherein a position of the second camera relative to the first camera is known, and wherein at least a first optical characteristic of the first camera is different from a first optical characteristic of the second camera;
b) automatically detecting an acceptable positioning of the first camera and the second camera when the first camera and the second camera are positioned to be within a predefined level of alignment relative to the patient's skin surface;
c) when the acceptable positioning is detected, automatically capturing image data of the patient's skin surface using the first camera and the second camera, the image data including a first image from the first camera and a second image from the second camera;
d) determining at least one common point in the first image and the second image; and
e) based on the at least one common point and on the known relative position, determining one or more dimensions of the feature on the patient's skin surface.
