Model separation method and device, terminal and computer storage medium

Abstract

The embodiment of the invention discloses a model separation method. The method comprises the following steps: obtaining a three-dimensional model containing a heart model according to the obtained three-dimensional model, constructing a three-dimensional matrix of the three-dimensional model; performing corrosion operation in morphology; performing operation on the three-dimensional matrix by adopting the constructed first-class three-dimensional matrix; obtaining a three-dimensional matrix after corrosion operation; performing expansion operation in morphology; calculating the three-dimensional matrix subjected to corrosion operation by adopting the constructed second-class three-dimensional matrix to obtain a three-dimensional matrix subjected to expansion operation, and subtracting thethree-dimensional matrix of the three-dimensional model from the three-dimensional matrix subjected to expansion operation to obtain a difference matrix so as to separate the auricle model from the model corresponding to the difference matrix. The embodiment of the invention also discloses a model separation device, a terminal and a computer storage medium.

Description

technical field [0001] The invention relates to the separation technology of the central ear model of the heart model, in particular to a model separation method, device, terminal and computer storage medium. Background technique [0002] The atrial appendage is an ear-shaped sac protruding from the atrium. It is a part of the atrium. It has active systolic and secretory functions, and is of great significance in alleviating the pressure increase in the atrium and ensuring the filling of the ventricle. [0003] From an anatomical point of view, the auricle is at the corner of the heart, and the blood flows slowly in the auricle, so it is easy to form blood clots. These blood clots fall off and flow to the whole body through the aorta, which may cause embolism in different parts, causing serious damage to the body, and even directly Life-threatening, such as: myocardial infarction, stroke, etc. [0004] Since the formation of thrombus in the auricle has a lot to do with the ...

AI Technical Summary

Problems solved by technology

[0004] Since the formation of thrombus in the auricle has a lot to do with the structure and shape of the auricle, the more complex the structure, the higher the probability of thrombus formation. Therefore, it is very important to study the shape of the auricle. In order to study the auricle, the auricle model needs to be Separated from the heart model, due to the small size and complex shape of the auricle, the cutting standards of the traditional manual separation method are not uniform, and people's cutting habits directly affect the analysis of the shape of the auricle and the calculation results of indicators, and the workload is heavy, making it difficult to batch process data; it can be seen from this that the existing method of manually separating the auricle model is cumbersome to operate and the effect is not good
