Abstract
Systems and methods for generating high resolution 3D images of the entire human skin comprising at least two sets of cameras, a first set being sensitive to UV light while the second set being sensitive to visible frequencies of light, wherein subsets of each camera set are focused at different focal distances; wherein the system provides a rotatable structure wherein the two sets of cameras are mounted adjacent to the source of light; wherein the rotatable structure is engaged to a program that can define the point of rotation, so as to allow for a reproducible mechanism to take images along the path of rotation.
Claims12
A system for generating wide depth of field and high resolution images comprising:
- two sets of cameras comprising a first camera set and a second camera set;
- a rotatable structure to which the first camera set and the second camera set are mounted for rotating the two sets of cameras around a subject, to produce wide depth of field of images in a high speed manner;
- wherein the first set of camera are focused at the first focus distance and the second set of camera are focused at a second focus distance, the cameras being mounted adjacent to at least one illumination source;
- wherein the rotatable structure is controlled by a program that defines a movement profile along a path of rotation,
- wherein the program moves the first and second sets of cameras around the subject, stops to specific angles of view and obtains images from all the cameras at each stop;
- wherein a subsequent incremental move of the structure will place the second set of cameras at the same angle of view of the subject as the set of first cameras in the next time increment;
- wherein after a set number movements, a full rotation of the structure around the subject is completed;
- wherein the images from the first set of cameras at time increment x are stitched together;
- wherein the images from the second sets of camera at time increment x+1 are stitched together;
- and
- wherein the resulting image from the stitching operations from the first set of cameras at time increment x and resulting image from stitching operations from the second set of cameras at time increment x+1 are stacked together to create very high resolution and large depth of field image from one angle of view. By repeating the same process for images obtained at the other angles of views along the path of rotation, the system can produce a plurality of wide depth of field and high resolutions images from all angles of views along a path of rotation.

An imaging device comprising a camera positioned on a movable boom;
- wherein the said movable boom is a curved boom with cameras located at equal distances along the curved boom and the curved can move from one extremity of the body to the other;
- wherein the said cameras comprise six line-scan sensors aligned parallel to one another, with three sets of two sensors having filters for one the three spectra of interest providing two line-scan sensors having UV pass filters, two sensors having IR pass filters and the last two filters having visible pass filter;
- wherein the camera comprising a lens, oriented at a tilt angle between 0 and 90 degrees, with respect to sensor plane, wherein the plane of focus will be at a tilt angle with the plane of sensors;
- wherein the angle of the tilt will be selected such that the furthest part of the plane of focus is at the same distance as the further part of a typical subject's body from the camera and the closed part of the plane of focus is at the same distance as the nearest part of a typical subject's body wherein each lines can sensors will be focused at a different focal distance due to the tilt of the lens.
