1-17. (canceled)
A method of capturing data concerning an anatomical surface feature on a patient's skin surface, including:
- directing a camera having a camera optical axis towards the patient's skin surface;
- projecting a light pattern onto the skin surface using a projection arrangement mounted in fixed relation to the camera, the pattern being formed by three or more fan beams that cross at a crossing point;
- adjusting a position of the camera and projection arrangement such that the crossing point falls on or near the patient's skin surface;
- and
- capturing data using the camera.
A method of capturing data concerning an anatomical surface feature on a patient's skin surface, using a camera and a projection arrangement in fixed relation to each other, the method including:
- projecting visible light from the projection arrangement onto the patient's skin surface;
- guiding a user to position the camera within an optimum distance range relative to the anatomical surface feature by:
- a. forming a first shape on the skin surface with the visible light when the camera is outside of an optimum distance range from the anatomical surface feature;
- and
- b. forming a second shape different from the first shape only when the camera is within the optimum distance range from the anatomical surface feature so that the user may position the camera within the optimum distance range by reference to the shape of the visible light on the skin surface;
- and
- capturing image data of the anatomical surface feature with the camera.
A method of capturing data concerning an anatomical surface feature on a patient's skin surface, using a camera and a structured light projection arrangement in fixed relation to each other, the method including:
- directing the camera towards a skin surface;
- projecting a structured light pattern onto the skin surface using the structured light arrangement, wherein the structured light pattern is arranged to define a region that substantially corresponds to an image frame of the camera;
- adjusting a position of the projection arrangement such that the structured light pattern defines a desired image region on the skin surface;
- and
- capturing data using the camera, including at least one image including structured light data.
