First Claim
Patent Images
1. A system for measuring blood content, comprising:
- a color imaging system configured to acquire a color image of a field of view comprising a surgical textile;
an infrared imaging system configured to acquire an infrared image of the field of view;
a processor configured to;
determine depth information for the surgical textile from the infrared image;
identify surgical textile pixels in the color image; and
extract blood information from the surgical textile pixels.

17. A computer-implemented method of analyzing an object containing a blood component, comprising:
-
acquiring a depth image and a color image of a field of view; using the depth image to determine the presence of a surgical textile in the field of view; and using the color image to estimate a characteristic of a blood component contained in the surgical textile. - View Dependent Claims (18, 19)
