摘要： A first image captured by a first camera can be aligned with at least a segment of a second image captured with a second camera, where the images have an overlapping field of view. Image characteristic values indicative of image characteristics at positions within the overlapping field of view of the first and second images are respectively determined. A difference in position between corresponding image characteristic values in the overlapping field of view in the first image and the overlapping field of view in the second image is determined. A transform is applied to the first image, adjusting an orientation of the first image relative to the second image. The first and second image can be aligned when the difference in position between corresponding image characteristic values in the first and second image is a predetermined amount.

摘要： A method of determining the amount of mis-alignment in one direction of an image of a scene, the image captured by a first camera is described. The method comprising the steps of: defining a line between a first point in the image and a second point in the image, the line extending in the direction of mis-alignment; defining a reference section in the scene to which the image is to be aligned, the reference section of the scene having a reference image characteristic; identifying an image characteristic at different points along the line in the image; and comparing the image characteristic at each point along the line with the reference image characteristic, and determining the amount of mis-alignment by determining the distance between the position of the reference image characteristic of the reference section captured in the image and the defined reference section in the scene.

摘要： Video signals which represent a scene as viewed by a camera are processed to combine a computer generated object with the video signals with the effect that the computer generated object appears within the scene when the video signals are displayed. The scene includes a first object. The process includes mapping a virtual model of the first object to a position of the first object within the scene so that the virtual model substantially corresponds with the real object. The virtual model has a degree of transparency such that the virtual model can be rendered as a substantially transparent virtual object within the scene. The process further includes detecting occluded regions of the virtual model. The occluded regions correspond to regions of the virtual model which are hidden from a virtual light source by the computer generated object. The process also includes modifying the degree of transparency of the virtual model at the occluded regions so as to generate modified transparency regions, and rendering the scene in combination with the computer generated object and the virtual model such that the modified transparency regions of the virtual model appear as shadows on the first object.
