Abstract
A handheld skin monitoring or measuring device includes a camera having a camera optical axis; and a structured light arrangement configured to project three or more laser fan beams such that the laser an beams cross at a crossing point in front of the camera.
Claims17
A handheld skin monitoring or measuring device, including:
- a camera having a camera optical axis;
- and
- a structured light arrangement configured to project three or more laser fan beams such that the laser fan beams cross at a crossing point in front of the camera.
A handheld skin monitoring or measuring device, including:
- a camera having a camera optical axis and a camera field of view;
- and
- a structured light arrangement configured to project three or more laser fan beams such that the laser fan beams cross at a crossing point in front of the camera, the laser fan beams subtending fan beam angles corresponding to the camera field of view, such that the ends of the laser beams projected onto a skin surface define a region that substantially corresponds to an image frame of the camera.
A method of capturing data concerning a skin feature using a handheld skin monitoring or measuring device, including:
- a camera having a camera optical axis and a camera field of view;
- a structured light arrangement configured to project three or more laser fan beams such that the laser fan beams cross at a crossing point in front of the camera;
- the laser fan beams subtending fan beam angles corresponding to the camera field of view, such that the laser beams projected onto a skip surface define a region that substantially corresponds to an image frame of the camera;
- the method including:
- directing the handheld. skin monitoring or measuring device towards a skin surface;
- projecting at least some of the laser fan beams using the structured light arrangement;
- and
- adjusting a position of the handheld skin monitoring or measuring device such that laser fan beams define a desired image region on the skin surface;
- and
- capturing data using the camera.
A display-less handheld skin monitoring or measuring device including:
- a substantially spherical housing dimensioned to fit the cupped hand of a user;
- a camera mounted in the housing;
- a structured light arrangement mounted in the housing and configured to project three or more laser fan beams such that the laser fan beams cross at a crossing point in front of the camera;
- and
- a communications link configured to transmit image data captured by the camera.
