Claim:
1. A method of determining a suitable pose for a camera for obtaining a stereoscopic image pair, the camera comprising an imaging sensor, the method comprising: obtaining and storing a first image of a scene using the imaging sensor when the camera is in a first pose; performing at least two iterations of obtaining a second image of the scene using the same imaging sensor when the camera is in a different, second pose; determining, for each iteration of obtaining the second image, one or more disparity vectors, each disparity vector being determined between a feature identified within the first image and a corresponding feature identified in the second image, wherein the disparity vector indicates the difference in location of the feature identified within the first image and the corresponding feature identified in the second image; and displaying to a user one or more disparity vectors overlaid on one of the first and second images displayed to the user; determining whether the second pose matches an optimal second pose based on the one or more disparity vectors, and a predetermined positional tolerance, wherein the second pose is optimal for recording a second image to be presented, together with the first image, as a stereoscopic image pair; and if the second pose does not match the optimal second pose: determining, on the basis of the one or more disparity vectors, whether the second image of the scene is suitable for use, together with the first image, as a stereoscopic image pair.
