Method and apparatus for capturing and analyzing thermo-graphic images of a moving object
First Claim
Patent Images
1. A method of correcting a distorted thermal image, comprising:
- capturing a first raw image of a moving object in a first position with a thermal imaging device, thereby obtaining a plurality of pixels that comprise the first raw image;
capturing a second raw image of the moving object in a second position with the thermal imaging device, wherein the second position generally varies in only one direction from the first position;
obtaining a speed of the moving object, wherein obtaining the speed of the moving object includes comparing the first raw image to the second raw image and analyzing the variation of the images with respect to a known frame rate of the thermal imaging device;
obtaining a response time for the thermal imaging device;
obtaining a correction factor to compensate for the distortion of the first raw image caused by the movement of the object, wherein the correction factor is dependent on the speed of the moving object and the response time of the thermal imaging device; and
applying the correction factor to the plurality of pixels, thereby obtaining a corrected image.

9. A computer-readable medium having computer-executable instructions for performing steps, comprising:
-
(a) obtaining a first raw image of a moving object from a thermal imaging device, the first raw image comprising a plurality of pixels of the moving object in a first position; (b) obtaining a second raw image from the thermal imaging device of the moving object in a second position; (c) obtaining a speed of the moving object, wherein obtaining the speed of the moving object includes comparing the first raw image to the second raw image and analyzing the variation of the images with respect to a known frame rate of the thermal imaging device; and (d) applying a correction factor to the plurality of pixels to obtain a corrected image of the moving object. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
