A method for visualising an image combining a captured image (Ic) of a real object originating from a video capture system with digital information (In) originating from a three-dimensional model of the recorded real object, comprising: - real-time registration processing of a reference of said three-dimensional model with a reference of the video capture system and a reference of said real object, - visualising by displaying at least some of said digital information inlayed on the image captured by said video capture system based on the real-time registration processing, - an initial step (Ei) of recording a reference texture of said real object, and - a step (Ea) of analysing the image (Ic) captured by the video capture system, with said analysis step comprising: - extracting (Ee) so-called visible zones (Zv) from said three-dimensional model whose texture corresponds to the recorded texture and so-called masked zones (Zm) from said three-dimensional model whose texture differs from the recorded texture, and - a step (Ec) of computing a synthesis image by mixing the masked zones (Zm) of said three-dimensional model with the recorded texture corresponding to the masked zones (Zm), and the visible zones (Zv) of said three-dimensional model with the texture extracted from the captured image (Ic) in the visible zones (Zv), and computing and visualising a composite image (Icomp) by mixing the synthesis image and the captured image (Ic). - real-time registration processing of a reference of said three-dimensional model with a reference of the video capture system and a reference of said real object, - visualising by displaying at least some of said digital information inlayed on the image captured by said video capture system based on the real-time registration processing, - an initial step (Ei) of recording a reference texture of said real object, and - a step (Ea) of analysing the image (Ic) captured by the video capture system, with said analysis step comprising: - extracting (Ee) so-called visible zones (Zv) from said three-dimensional model whose texture corresponds to the recorded texture and so-called masked zones (Zm) from said three-dimensional model whose texture differs from the recorded texture, and - a step (Ec) of computing a synthesis image by mixing the masked zones (Zm) of said three-dimensional model with the recorded texture corresponding to the masked zones (Zm), and the visible zones (Zv) of said three-dimensional model with the texture extracted from the captured image (Ic) in the visible zones (Zv), and computing and visualising a composite image (Icomp) by mixing the synthesis image and the captured image (Ic). - extracting (Ee) so-called visible zones (Zv) from said three-dimensional model whose texture corresponds to the recorded texture and so-called masked zones (Zm) from said three-dimensional model whose texture differs from the recorded texture, and - a step (Ec) of computing a synthesis image by mixing the masked zones (Zm) of said three-dimensional model with the recorded texture corresponding to the masked zones (Zm), and the visible zones (Zv) of said three-dimensional model with the texture extracted from the captured image (Ic) in the visible zones (Zv), and computing and visualising a composite image (Icomp) by mixing the synthesis image and the captured image (Ic).
