Embodiment Construction

[0098] figure 1 A schematic diagram of a scene imaged by separate visible and infrared cameras is shown and is used here to illustrate the parallax problem.

[0099] Such as figure 1 As shown in , an object of interest 1 exists within a scene that is visible in the fields of view of both the visible light camera 2 and the infrared camera 3 . The object of interest 1 is shown as a circle. Also in the scene visible to the two cameras 2 and 3, there are a number of foreground objects 4a to 4c in the foreground, including a triangle 4a, a square 4b and a pentagon 4c. In the background there are a number of further background objects 5a to 5c, represented as crosses 5a, hexagons 5b and stars 5c. From the perspective of the visible light camera 2, the object of interest 2 appears to be located between the square 4b and the pentagon 4c in the background, and also appears to be located between the cross 5a and the hexagon 5b in the foreground. From the perspective of the infrared ...

Abstract

The invention relates to an apparatus and method for multispectral imaging comprising: representation generating means arranged to generate a three-dimensional representation of a scene; at least one infrared imaging sensor arranged to obtain an infrared image of said scene; and superposition means, is arranged to overlay the infrared image onto the three-dimensional representation of the scene to produce an infrared three-dimensional representation of the scene.

Description

technical field [0001] The present invention relates to devices and methods for multispectral imaging. In particular, the present invention relates to methods and apparatus for combining visible and infrared images of a scene in order to provide a combined multispectral image that has been parallax corrected. [0002] The present invention also relates to apparatus and methods for multispectral imaging including three-dimensional overlay of visible and infrared images of a scene, and in particular to apparatus and methods for enhancing the visibility of displayed thermal information of imaged objects within a scene . Background technique [0003] Infrared images of a scene can be used to provide information not available from visible light images, such as temperature information not discernible in visible light images. [0004] However, infrared imaging systems often operate at lower spatial image resolution levels than provided by visible light imaging systems. [0005] ...
