Abstract
A method for recognizing surfaces, in particular for optically recognizing or identifying structured and/or pictorial surfaces involves the steps of: focusing a camera onto a prominent image dot on the surface; creating at least one live video stream of a recognizable, high-contrast area of the image dot; guiding the camera to the image frame of the video having the greatest depth of detail by focusing the camera onto a prominent image dot on the surface to be sensed; creating at least two images of a recognizable, high-contrast area of the image dot; storing the image having the greatest depth of detail as a reference image; analyzing each image frame of the live video stream; and comparing the image frame having the greatest depth of detail with a target image or reference image.
Claims17
A method for recognizing and/or for capturing structured and/or pictorial surfaces using a mobile device, the method comprising:
- focusing a camera of the mobile device on a prominent image dot of a surface to be recognized and/or captured;
- creating at least one live video stream of a recognizable and/or capturable, high-contrast area of the prominent image dot;
- guiding the camera to an image of the live video stream with the largest number of details by focusing the camera on the prominent image dot of the surface;
- creating at least two images of the live video stream of the recognizable and/or capturable, high-contrast area of the prominent image dot using the camera;
- analyzing each image of the live video stream to determine a number of details in each image;
- storing the image with the largest number of details as a reference image;
- and
- comparing the image with the largest number of details with a target image.
A method for recognizing and/or for capturing structured and/or pictorial surfaces using a mobile device, the method comprising:
- focusing a camera of the mobile device on a prominent image dot of a surface;
- creating at least one live video stream of a recognizable, high-contrast area of the prominent image dot;
- analyzing images of the live video stream to determine a number of details in each of the images;
- and
- storing the image with the largest number of details as a reference image.
A method for recognizing and/or for capturing structured and/or pictorial surfaces using a mobile device, the method comprising:
- focusing a camera of the mobile device on an image dot of a surface;
- storing a single image of a recognizable, high-contrast area of the image dot as a reference image;
- creating at least one live video stream of the recognizable, high-contrast area of the image dot;
- analyzing a plurality of images from the live video stream to determine a number of details in each of the images;
- and
- storing the image from the live video stream with the largest number of details as the reference image if it has more details than the single image.
