description | The invention relates to a method and a device for acquiring the diameter of an air inlet lip, belongs to the technical field of measurement, and is used for solving the problem that a result conforming to the actual state of a product cannot be obtained by an existing method for calculating the diameter of the air inlet lip. The method for acquiring the diameter of the lip of the air inlet channel comprises the following steps: performing laser scanning on the air inlet channel to obtain point cloud data of the air inlet channel, and aligning the point cloud data of the air inlet channel with a theoretical model; taking one cross section of the lip in the theoretical model as a shearing plane, and performing section shearing on the aligned point cloud data and the theoretical model to obtain a shearing sketch; stroking the point cloud data of the lip on the cut sketch to form an actual lip curve; processing the point cloud data of the two side plates on the cut sketch to obtain an actual included angle of th |
