Method and apparatus for determining the mis-alignment in images

An apparatus for determining an amount of a mis-alignment in a direction of a first image of a scene, the first image captured by a first camera, the apparatus comprising:

• a first definer configured to define a first line between a first point in the first image and a second point in the first image, the first line being extended in the direction of the mis-alignment, and configured to define a reference section in the scene to which the first image is being aligned, the reference section of the scene having a first reference image characteristic;
• an identifier configured to identify a first image characteristic at a first plurality of points along the first line in the first image;
• a comparator configured to compare the first image characteristic at each point of the first plurality of points along the first line with the first reference image characteristic, and to determine the amount of the mis-alignment by determining a distance between a position of the first reference image characteristic of the reference section captured in the first image and the defined reference section in the scene;
• and
• a second definer configured to define at least one of a circular or radial sampling path in the first image, the circular sampling path defining a circular path between the first point and the second point and a radial sampling path passing through a centre point of the first image coincident with a corresponding point in the first image and extending along a radial line therefrom, the first line between the first and the second points in the image being defined by one or more of the circular sampling path or the radial sampling path.
