Embodiment Construction

[0039] The present invention will be further described below through specific embodiments.

[0040] Such as figure 1 As shown, the head three-dimensional data processing method for medical diagnosis and treatment assistance in the embodiment of the present invention includes the following steps:

[0041] (1) Model acquisition, the 3D model of the head is obtained through a 3D scanner, imported and processed in the form of point cloud data; the initial scanning position is unified in front of the patient, so that the angle can be fine-tuned during subsequent point cloud alignment;

[0042] (2) Point cloud preprocessing, the processing at the point cloud level of the 3D model is easily disturbed by outliers, and the unstructured point cloud data will also affect the accuracy and efficiency of the processing operation, so statistical filtering is performed on the point cloud first Eliminate the outlier interference points outside the object, move the coordinate system to the cen...

Abstract

The invention belongs to the technical field of data processing, and particularly relates to a head three-dimensional data processing method for medical diagnosis and treatment assistance, which comprises the following steps of S1, acquiring a head three-dimensional model, and importing the model in a point cloud data form; S2, preprocessing and aligning the point cloud; S3, searching and calculating the size of each key point position of the head; and S4, displaying the head three-dimensional model and marking key points on the head three-dimensional model. According to the head three-dimensional data processing method for medical diagnosis and treatment assistance, and compared with a traditional naked eye observation diagnosis and treatment means, the three-dimensional technology and the point cloud data processing method adopted by the present invention can provide the accurate, rapid and visual patient information display while the multi-dimensional information is collected, the size change analysis result of each key point of the head of the patient is directly presented, and a reliable and accurate basis is provided for health diagnosis of the patient.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a head three-dimensional data processing method for medical diagnosis and treatment assistance. Background technique [0002] Anthropometry is an important branch of ergonomics, which studies the morphological characteristics of the human body by measuring the size of various parts of the human body and using statistical methods. Head measurement is an important part of anthropometry, and it is of great significance to the quantitative analysis of a patient's head. [0003] With the continuous development of computer technology, its application permeates all walks of life. Among them, intelligent medical care is an eye-catching field. For patients with autism and neurosis who may have concentrated pathological features on the head, it can be quantitatively displayed through 3D scanning technology and point cloud processing technology. Changes in key dimensio...
