Thermal imager that analyzes temperature measurement calculation accuracy

A computer program product, comprising a computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for determining whether an object of interest can have its temperature measurement accurately calculated by a thermal imaging camera, said method comprising:

• a) displaying a measurement IFOV on a display of the camera as a graphical box;
• and
• b) registering the graphical box with the image of the object of interest on the display.

A method of determining whether an object of interest can have its temperature measurement accurately calculated by a thermal imaging camera comprising:

• a) generating temperature data of an object of interest in the form of a pixel matrix comprised of multiple pixels;
• and
• b) performing a statistical analysis on the data generated by the pixel matrix to determine uniformity of the data generated by the pixel matrix.

A portable, hand-held thermal imaging camera comprising:

• a lens assembly having an associated sensor for detecting thermal images of a target scene;
• a display adapted to display at least a portion of the thermal image;
• a processor programmed to calculate a measurement IFOV in linear units and display the calculated measurement IFOV in linear units on the display.
