Apparatus and method for multispectral imaging with parallax correction
First Claim
1. An apparatus for multispectral imaging, comprising:
- a cyclopean camera arrangement comprising at least two spaced apart imaging sensors operating at a first waveband;
an image combiner arranged to combine images from the at least two spaced apart imaging sensors to provide a first cyclopean image of a scene from a first virtual position;
a further imaging sensor operating at a second waveband different from the first waveband and arranged to provide a second image of the scene from a second position;
image combining means arranged to combine the first cyclopean image and second image of the scene to provide a multispectral image;
means for selecting objects of interest within the scene; and
depth sensing means configured to determine a depth or distance of objects and surfaces in the scene from differences between the images from the at least two spaced apart imaging sensors operating at the first waveband;
wherein the first virtual position of the cyclopean camera arrangement and the second position of the further sensor are arranged to be substantially the same; and
wherein either the first waveband is infrared and the first cyclopean image is represented via a false color palette or the second waveband is infrared and the second image is represented via a false color palette; and
the false color palette used to represent either the first cyclopean image or the second image extends only over the range of temperatures observable within a range of interest, the range of interest corresponding to depths between a specified minimum depth and a specified maximum depth.

Abstract
An apparatus and a method for multispectral imaging that may, comprising a cyclopean camera arrangement comprising at least two spaced apart imaging sensors operating at a first waveband, an image combiner arranged to combine images from the at least two spaced apart imaging sensors to provide a first cyclopean image of a scene from a first virtual position, a further imaging sensor operating at a second waveband different from the first and arranged to provide a second image of the scene from a second position, and a second image combiner arranged to combine the first and second images of the scene to provide a multispectral image, wherein the first virtual position of the cyclopean camera arrangement and the second position of the further sensor are arranged to be substantially the same.

15. A method for multispectral imaging, comprising:
-
obtaining a first cyclopean image of a scene from a first virtual position using a cyclopean camera arrangement comprising at least two spaced apart imaging sensors operating at a first waveband by combining images from the at least two spaced apart imaging sensors to provide the first cyclopean image of the scene; obtaining a second image of the scene from a second position using a further imaging sensor operating at a second waveband different from the first waveband, and wherein either the first waveband is an infrared waveband and the first cyclopean image is represented via a false color palette or the second waveband is an infrared waveband and the second image is represented via a false color palette; combining the first cyclopean image and the second image of the scene to provide a multispectral image; selecting an object of interest within the scene; determining a depth or distance of objects and surfaces in the scene from differences between the images from the at least two spaced apart imaging sensors operating at the first waveband; and adjusting the false color palette used to represent either the first cyclopean image or the second image in the multispectral image to extend only over the range of temperatures observable within a range of interest, the range of interest corresponding to depths between a specified minimum depth and a specified maximum depth; wherein the first virtual position of the cyclopean camera arrangement and the second position of the further sensor are arranged to be substantially the same. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
