Abstract: A method to determine the misalignment and/or clearance of a door relative to its frame includes a phase to determine a law of variation of the clearance and/or misalignment values for the different inspection points, in relation to various opening positions of the door taken with respect to a reference position in which the door occupies its closed position, a measurement phase in which the door occupies any position relative to the frame, and during which the clearance and/or misalignment values are measured, and a phase to take into account the measured clearance and/or misalignment values and the law of variation so as to determine the true values of clearance and/or misalignment at the different inspection points corresponding to the door in its reference closed position.
