Embodiment Construction

[0068] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention, and those skilled in the art can also obtain other accompanying drawings based on these drawings and obtain other implementations.

[0069] During orthodontic treatment, it is usually necessary to observe the shape of contour lines in different regions on the patient's cephalometric film, so as to judge the medical characteristics of the patient's skull and teeth. The existing contour line generation is mainly based on the edge detection method, which has a large amount of calculation, slow speed, and is easy to miss. The basis of the line is the calibration accuracy of the marker points, and the accuracy ...

Abstract

The invention discloses a method and system for constructing a contour line in a skull lateral position film, electronic equipment and a computer storage medium. The construction method comprises the steps: mapping a preset contour line template into a skull coordinate system of a current skull lateral position film, respectively extracting position information of a preset mark point in the current skull lateral position film, position information of a template mark point on a preset contour line template and position information of a contour adjusting point; comparing the position information of the template mark point with the position information of the preset mark point, and constructing a mark point position transformation relation between the position information of the preset mark point and the position information of the template mark point by utilizing an affine transformation matrix algorithm according to a comparison result; inputting the position information of the contour adjusting point into the mark point position transformation relation to obtain the position information of a dynamic adjustable mark point of the current skull lateral position film; and according to the position information of the preset mark point and the position information of the dynamic adjustable mark point, constructing a contour line meeting diagnosis and treatment parameters on the current skull lateral position film.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and more precisely relates to a method and system for constructing a contour line in a cephalometric film, electronic equipment, and a computer storage medium. Background technique [0002] In the process of orthodontic treatment, the cephalometric film is one of the criteria used by doctors to judge whether the patient is dental or bony protruding. Specifically, in the process of diagnosis and treatment, it is necessary to observe the contour lines of different regions on the patient's cephalometric film. The shape of the patient's skull and teeth can be judged in order to judge the medical characteristics of the patient. [0003] The automatic measurement and analysis of X-ray projection makes the diagnosis and treatment design of dental and maxillofacial deformities more accurate, and greatly reduces the burden on the operator. However, the accuracy of the positioning of the marker point...
