In the method a portable terminal executes and displays a human-machine interface (HMI), and the terminal visualizes through display means at least one module of said production line. The method performs a geographical localization of said terminal within a three-dimensional reference frame centered on said production line and determining the position of said terminal with respect to said module. The method also displays via said display means in superimposition a virtual model limited to said module as a function of said determined position of said terminal. ## Claims ### Claim 1 A method for computer assistance in the management of a production line (1), in which, furthermore: a portable terminal (3) executes and displays a human-machine interface (HMI) (4); said terminal (3) shows, by way of display means, at least one module (2) of said production line (1); wherein it comprises at least the following steps: geographically locating said terminal (3) within a three-dimensional frame of reference (5) centered on said production line (1) and determining the position of said terminal (3) with respect to said module (2); displaying, via said display means and in superposition, a virtual model (7) limited to said module (2) according to said determined position of said terminal (3). ### Claim 2 (depends on 1) The assistance method as claimed in claim 1, wherein the position of said terminal (3) is determined by means of at least one three-dimensional position sensor (8) connected to said terminal (3). ### Claim 3 (depends on 2) The assistance method as claimed in claim 2, wherein the orientation of said terminal (3) is determined by way of at least a first and a second three-dimensional position sensor (8) which are spaced apart from each other and are connected to said terminal (3). ### Claim 4 (depends on 1) The assistance method as claimed in claim 1, wherein said display means comprise a screen and a video stream of said module (2) is captured and is displayed by way of said screen. ### Claim 5 (depends on 1) The assistance method as claimed in claim 1, wherein said display means comprise a translucent surface and said limited virtual model (7) is holographically displayed on said translucent surface. ### Claim 6 (depends on 1) The assistance method as claimed in claim 1, wherein said frame of reference (5) is centered by positioning at least two transmitting/receiving bases (6) so as to be spaced apart from each other and located on said production line (1). ### Claim 7 (depends on 2) The assistance method as claimed in claim 2, wherein said display means comprise a screen and a video stream of said module (2) is captured and is displayed by way of said screen. ### Claim 8 (depends on 3) The assistance method as claimed in claim 3, wherein said display means comprise a screen and a video stream of said module (2) is captured and is displayed by way of said screen. ### Claim 9 (depends on 2) The assistance method as claimed in claim 2, wherein said display means comprise a translucent surface and said limited virtual model (7) is holographically displayed on said translucent surface. ### Claim 10 (depends on 3) The assistance method as claimed in claim 3, wherein said display means comprise a translucent surface and said limited virtual model (7) is holographically displayed on said translucent surface. ### Claim 11 (depends on 2) The assistance method as claimed in claim 2, wherein said frame of reference (5) is centered by positioning at least two transmitting/receiving bases (6) so as to be spaced apart from each other and located on said production line (1). ### Claim 12 (depends on 3) The assistance method as claimed in claim 3, wherein said frame of reference (5) is centered by positioning at least two transmitting/receiving bases (6) so as to be spaced apart from each other and located on said production line (1). ### Claim 13 (depends on 4) The assistance method as claimed in claim 4, wherein said frame of reference (5) is centered by positioning at least two transmitting/receiving bases (6) so as to be spaced apart from each other and located on said production line (1). ### Claim 14 (depends on 5) The assistance method as claimed in claim 5, wherein said frame of reference (5) is centered by positioning at least two transmitting/receiving bases (6) so as to be spaced apart from each other and located on said production line (1).
