Abstract
A method for assessing contrasts on surfaces, in particular for optically identifying structured and/or pictorial surfaces, e.g. of paintings or sculptures, is simple to use independently of the location and safe. For this purpose, the method involves the steps of: focusing a camera onto a prominent image dot on the surface; creating at least two images of a recognizable, high-contrast area of the image dot; and storing the image having the greatest depth of detail as a reference image.
Claims11
A method for assessing contrast on surfaces, the method comprising:
- focusing a camera on an image dot of a surface;
- after focusing the camera, creating at least two images of a recognizable, high contrast area of the image dot;
- determining a number of details in each of the at least two images, and storing the image with the highest number of details as a reference image;
- after focusing the camera, calculating an actual distance to the image dot of the surface based on a physical lens position of the camera.

A method for assessing contrasts on surfaces, the method comprising:
- focusing a single camera on an image dot of a surface;
- after focusing the single camera, using the single camera to create at least two images of a recognizable, high contrast area of the image dot;
- determining a number of details in each of the at least two images;
- and storing the image with the highest number of details as a reference image;
- after focusing the camera, calculating an actual distance to the image dot of the surface based on a physical lens position of the camera.
