A computer 3D model is the central point of both the modern production process and its preparation by the concurrent design using. Such model often needs to be constructed from a physical part. It is so called Reverse Engineering process, which is performed through three-dimensional digitizing and CAD modeling. In the paper the low-cost 3D digitizer on video camera base is offered. The results of functional and structural modeling of this compact Reverse Engineering system are given. A method of the automated input of a number of the 2D images of a 3D irregular physical object, its processing and transformation into 3D computer model and then to the new physical object by the means of Rapid Prototyping is offered. The results of theoretical and practical studies of the parameters of the offered Reverse Engineering process realization are discussed.
