The goals of the computation that extracts disparity from pairs of pictures of a scene are defined, and the constraints imposed upon that computation by the three-dimensional structure of the world are shown to be inadequate. A precise expression of the goals of the computation is possible in a low-level symbolic visual processor the constraints translate in this environment to pre-requisites on the binding of disparity values to low-level symbols. The outline of a method based on this is given.
