Method and system for acquiring scales of measuring scale in skull lateral position sheet

Abstract

The invention provides a method and a system for detecting a measuring scale in a skull lateral position sheet. The method comprises the following steps: determining a picture of the skull measuring scale in the skull lateral position sheet according to skull mark points; performing digital processing on the picture of the skull measuring scale according to a first preset algorithm, and determining relative position information of the skull measuring scale in the skull lateral position sheet; performing image processing on the skull measuring scale map according to a second preset algorithm, and obtaining a scale gap of the skull measuring scale and a scale phase of the scale in the skull side position sheet; and calculating the scale of the skull measuring scale according to the scale gap of the skull measuring scale and the scale phase of the scale in combination with the human maxillary length mean value. The problems that in the prior art, the scaleplate distance of the skull side position piece needs to be manually participated, distance data have errors, and efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and more precisely relates to a method and system for acquiring the scale of a measuring scale in a cephalometric film, electronic equipment, and a computer storage medium. Background technique [0002] Cephalometric X-ray is one of the criteria for doctors to judge whether a patient is dental or bony convex. Standard measurement software is used to measure the relevant data and compare with the standard value, so that the diagnosis and treatment of dental and maxillofacial deformities The design is more accurate. In the process of calculating the relevant measurement values, in addition to identifying the landmarks on the cephalometric film, it is also necessary to detect the scale on the cephalometric film in order to accurately and quantitatively give the measurement data. [0003] At this stage, the scales of most cephalometric films need to manually point out two points on the scale, a...
