24.8 We wish to use the alignment algorithm in an industrial situation where flat parts are moving along a conveyor belt and being photographed by a camera vertically above the conveyor belt. The pose of the part is specified by three variables, one for the rotation and two for the 2-D position. This simplifies the problem and the function FlND-TRANSFORM needs only two pairs of corresponding image and model features to determine the pose. Determine the worst-case complexity of the alignment procedure in this context.
