Method for analysing content of at least one image of a structured document which may be deformed, said method being implemented by an analysis device configured to be connected to a storage device storing: reference document templates each associated with regions of interest and points of interest contained within said regions of interest, and with at least one region to be analysed, said points of interest of a given reference document template having a fixed location in any document structured according to said given reference document template, each reference document template being further associated with a reference image of a document according to said template, and characterized in that it comprises steps of: - acquiring said at least one digital image of said document; - selecting at least one initial reference document template from the reference document templates stored in the storage device according to a machine-readable zone of the acquired image; - for each stored region of interest of each of said selected initial reference document templates: • extracting points of interest from the acquired image, • matching the extracted points of interest with the stored points of interest of said region of interest of the initial reference document template, - selecting a final reference document template from said selected initial reference document templates, based on said matches, - estimating a geometric transformation between the acquired image and the reference image associated with the final reference template, taking into account the local deformations of the document by means of affine functions or homographies, and based on said matches, - determining at least one region to be analysed of said acquired image by projecting the at least one region to be analysed of the final reference document template into said acquired image as a function of said estimated geometric transformation, - analysing the content of said at least one region to be analysed of the determined acquired image. said method being implemented by an analysis device configured to be connected to a storage device storing: reference document templates each associated with regions of interest and points of interest contained within said regions of interest, and with at least one region to be analysed, said points of interest of a given reference document template having a fixed location in any document structured according to said given reference document template, each reference document template being further associated with a reference image of a document according to said template, and characterized in that it comprises steps of: - acquiring said at least one digital image of said document;
