Apparatus and method for infrared imaging with performance algorithm
First Claim
1. A process for analyzing the performance of an object in an image produced by a portable infrared imaging apparatus, the process comprising the following steps:
- (a) defining a thermal zone in the image, the thermal zone having a boundary;
(b) determining a first image expanse between a first point and a second point on the boundary of the thermal zone, the first point and the second point being spaced apart a known reference distance;
(c) determining a second image expanse between a third point and fourth point spaced apart a first unknown distance in the image;
(d) calculating a first estimated distance between the third point and the fourth point in the image using the known reference distance and a ratio between the first image expanse and the second image expanse.

Abstract
A system and method for enhancing inspections using infrared cameras through in-field displays and operator-assisted performance calculations. A handheld infrared imaging system typically includes an infrared camera having a programmed computer and an interactive user interface suitable for displaying images and prompting response and accepting input from the infrared camera operator in the field during an inspection. An operator may designate at least one thing of interest on a displayed infrared image; and the programmed computer may use a performance algorithm to estimate performance associated with the thing of interest. The programmed computer may extract information or parameters from previously measured data. The programmed computer may vary the way in which it displays new measurements based on the information extracted from the stored data. One or more of the parameters extracted from the IR image may be adapted to provide an automated alert to the user.
