【Abstract】 To domestic plants,there are rarely other kinds of technical data for some inward advanced products and equipment,except for photos.As a result,these products and equipment can’t be further understood or made use of.Through study on principium of prospective and photograph as well as comparison of it and the way that people observe objects,it is concluded that photos can be treated as prospective.With image information of equipment,based on reverse thinking of principium of prospective,a new way for converse drawing using two-point perspective is introduced here.更多还原
