The present invention relates generally to an optical character recognition of machine-readable forms, and in particular to a verification of a direction of spatial orientation and a definition of a form type of the document electronic image. The goals of the invention are achieved by preliminarily assigning one or more form objects as elements composing a graphic image unambiguously defining its direction of spatial orientation. Similarly, one or more form objects are preliminarily assigned as elements composing a graphic image unambiguously defining its type. The direction of spatial orientation and the type of the form are verified via identification of said images. The models of graphic images either for verification the direction of spatial orientation or for defining the form type are stored in a special data storage means, one of the embodiment of which is form model description.
