Claim 0:
1. A method of color calibrating a three-dimensional image related to the medical field,
said method comprising the steps of:
capturing one or more two-dimensional images of a subject on an image recording device, wherein the one or more two-dimensional images include a calibration slate appearing in the one or more two-dimensional images, wherein the calibration slate has a print run number that identifies a batch of printed calibration slates which includes the calibration slate appearing in the one or more two-dimensional images, a unique identifier that individually identifies the calibration slate appearing in the one or more two-dimensional images, and a color chart comprising at least one color;
generating point cloud data relating to the subject of the one or more two-dimensional images;
constructing a three-dimensional model of the subject utilizing the point cloud data;
applying the one or more two-dimensional images to the three-dimensional model to produce a three-dimensional image of the subject, wherein the three-dimensional image shows the calibration slate that appears in the one or more two-dimensional images;
reading the unique identifier and validating the calibration slate based on the unique identifier;
measuring a numeric color value from the at least one color in the color chart of the calibration slate appearing in the one or more two-dimensional images;
reading the print run number;
associating the print run number with the batch of printed calibration slates which includes the calibration slate appearing in the one or more two-dimensional images, wherein each calibration slate in the batch is substantially similar, wherein the measured numeric color value has a corresponding known numeric color value associated with the batch of calibration slates;
comparing the measured numeric color value to the corresponding known numeric color value;
calculating a variance between the measured numeric color value and the corresponding known numeric color value;
calculating a calibration factor based on the variance between the measured numeric color value and the corresponding known numeric color value; and
color calibrating the three-dimensional image by adjusting the colors of the one or more two-dimensional images or of the three-dimensional image to produce a calibrated three-dimensional image, wherein the colors are adjusted by applying the calibration factor to numeric color values measured from the one or more two-dimensional images or from the three-dimensional image.
