SYSTEM AND METHOD FOR DETECTING A CAMERA
First Claim
Patent Images
1. A system for detecting an optical device, comprising:
- an illumination system for illuminating a target area;
an image acquisition system for capturing a first image of the target area on the same axis as the illumination system and for capturing a second image of the target area on a different axis from the illumination system; and
a processor and computer readable media having computer code for causing a processor to identify retro-reflections in the target area by analyzing the first image and the second image.

Abstract
A system and method for detecting a camera. In one embodiment, although not limited thereto, an illuminator illuminates an area of interest. A camera then takes multiple pictures of the illuminated area and an algorithm is then used to compare the pictures and locate and pirate cameras based on the reflection characteristics.

23. A method of detecting an optical device, comprising the steps of:
-
(a) acquiring a first image of a target area on the same axis as an illumination source; (b) acquiring a second image of the target area on a different axis from the illumination source; and (c) identifying retro-reflections in the target area by analyzing the first image and the second image by; filtering the first image; creating an image mask using the second image; applying the image mask to the first image; and separating features in the foreground in the first image larger than a predetermined size. - View Dependent Claims (24)

25. A system for detecting an optical device, comprising:
-
means for illuminating a target area with illumination; means for capturing a first image of the target area on the same axis as the illumination; means for capturing a second image of the target area on a different axis from the illumination; a processor and computer readable media having computer code for causing a processor to identify retro-reflections in the target area by; filtering the first image; creating an image mask using the second image; applying the image mask to the first image; and separating features in the foreground in the first image larger than a predetermined size.
