Abstract
Systems and methods according to one or more embodiments are provided for determining an emitted radiation intensity of an object in a thermal image. In one example, a system includes a memory component configured to store a plurality of captured thermal images of a scene and a processor. The processor is configured to select a pixel on a thermal image corresponding to a measured radiation intensity associated with an object in the scene. Real world coordinates of the object are determined. An emitted radiation intensity of the object is calculated using the determined real world coordinates and the measured radiation intensity. Additional systems and methods are also provided.
Claims18
A method comprising:
- capturing first and second thermal images of a scene by an image capture component;
- selecting a first pixel of the first thermal image and a second pixel of the second thermal image, wherein the first and second pixels have values corresponding to first and second measured thermal radiation intensity values associated with an object in the scene;
- determining coordinates of the object in the scene by:
- determining a first location of the selected first pixel and a different second location of the selected second pixel, the first location and the different second location on an image plane associated with the image capture component,
- determining an angle defined by the image capture component and the first location of the selected first pixel and the different second location of the selected second pixel, and
- determining the coordinates of the object corresponding to the first and second pixels using the first and second measured thermal radiation intensity values and the angle;
- and
- calculating an emitted thermal radiation intensity of the object using the determined coordinates and the first and second measured thermal radiation intensity values to compensate for attenuation associated with transmission of the emitted thermal radiation from the scene to the image capture component.
