Abstract

An image capturing system comprises an image capturing device mounted on a support so as to be manually adjustable in three dimensions relative thereto. The system further comprises analysis apparatus for determining the presence of any part of said support in the field of view of said image capturing device and/or its appearance in an image captured by said image capturing device.

Claims

1. An image capturing system, comprising an image capturing device mounted on a support so as to be manually adjustable in three dimensions relative thereto, and analysis apparatus for determining the presence of any part of said support in the field of view of said image capturing device and/or its appearance in an image captured by said image capturing device.

2. An image capturing system according to claim 1, wherein said analysis apparatus is arranged for detecting the presence of any part of the support and for removing or masking the detected part or parts of the support from the final image output by said image capturing device.

3. An image capturing system according to claim 2, wherein said analysis apparatus is arranged for separating part of a captured image from one or more other parts of said captured image, and for disregarding any pixels in the image corresponding to the detected part or parts of the support.

4. An image capturing system according to claim 2, wherein said analysis apparatus is arranged for separating part of a captured image from one or more other parts of said captured image, for assigning a particular colour to said one or more other parts of the captured image, and for filling said detected part or parts of the support with said particular colour.

5. An image capturing system according to claim 1, wherein said analysis apparatus is arranged to store a two or three-dimensional model of at least the support, and to apply an object matching algorithm to an image captured by said image capturing device so as to determine the presence and/or location of said part or parts of the support in the image.

6. An image capturing system according to claim 1, wherein said support is provided with one or more markings, indentations, or similar features which are relatively easy to detect, to facilitate the determination or estimation of the location of said image capturing device relative to said support, or vice versa.

7. An image capturing system according to claim 1, arranged to analytically compute the appearance of the support in an image captured by the image capturing device using determined or estimated relative locations of the image capturing device and the support.

8. An image capturing system according to claim 7, arranged to take into account the constrained relative positions of the image capturing device and the support.

9. An image capturing system according to claim 1, wherein said analysis apparatus is arranged to predict the appearance of the support in a captured image using data received from sensors which determine image capturing device orientation, pitch and/or altitude relative to the support, and/or with full feedback relating to the position of the image capturing device (using knowledge of the joint angles, etc).

10. An image capturing system according to claim 1, wherein said analysis apparatus is arranged to employ an object matching algorithm to match one (or more) key feature(s) of the support within a captured image and estimate the position of the support in the image as a starting point for a subsequent image-based detection process to more accurately determine the appearance of the support in the image.

11. A camera arrangement comprising a support including an articulated arm on which a camera is mounted for movement relative to the support, and including a system for determining the presence of any part of said support in the field of view of said camera and/or its appearance in an image captured by the camera.

12. An image capturing system, comprising an image capturing device mounted on a support so as to be movable relative thereto, and an image data processor for determining the presence of any part of said support in the field of view of said image capturing device and/or its appearance in an image captured by said image capturing device, wherein said image data processor is arranged to determine the presence or appearance of part or parts of the support, to store a two or three-dimensional model of at least the support, and to apply an object matching algorithm to an image captured by said image capturing device so as to determine the presence and/or location of said part or parts of the support in the image.

13. An image capturing system, comprising an image capturing device mounted on a support so as to be movable relative thereto, and an image analysis system for determining the presence of any part of said support in the field of view of said image capturing device and/or its appearance in an image captured by said image capturing device, wherein said image analysis system is arranged to employ an object matching algorithm to match one (or more) key feature(s) of the support within a captured image and estimate the position of the support in the image as a starting point for a subsequent image-based detection process to more accurately determine the appearance of the support in the image.
