Method of evaluating a chain (1) for producing and viewing stereoscopic images of a scene (2), implemented by a computer (10), comprising:- a step (E1) of obtaining picture-capture parameters and viewing parameters characterizing said production and viewing chain (1), - a step (E3) of evaluating a viewing quality criterion as a function of said picture-capture parameters and of said viewing parameters, said viewing quality criterion comprising a viewing comfort criterion evaluated by verifying that, for any real depth (z) of the scene (2), the restored depth (Z) lies in a predetermined interval (ZminD0F, ZmaxD0F). The method is such that the viewing quality criterion furthermore comprises a criterion of preserving shapes or dimensions and that it comprises: - a step (E3) of evaluating the criterion of preserving shapes or dimensions by verifying that the shape or the dimension of the restored objects of the scene is not modified, - a step (E4) of issuing a warning when at least one of the viewing comfort or preservation of shapes or dimensions criteria is not satisfied.
