Problems solved by technology

[0002] In the medical imaging information processing system, 3D reconstruction technology can quickly and comprehensively obtain 3D data information, but there is a large amount of redundant information in the obtained point cloud data. If the point cloud data is directly stored and processed, it will occupy a large number of computers. Memory, which consumes a lot of time in the process of point cloud reconstruction, affects the processing efficiency of point cloud data

Abstract

The invention provides a point cloud data simplification method and device, a storage medium and an electronic device, and belongs to the technical field of digital medical treatment. The method comprises the steps of obtaining to-be-processed point cloud data, and calculating a curvature change rate corresponding to each point in the to-be-processed point cloud data; identifying boundary points from points contained in the point cloud data to be processed according to the curvature change rate corresponding to each point; based on the boundary points, clustering points contained in the to-be-processed point cloud data by adopting a clustering algorithm to obtain a point set corresponding to each boundary point; and according to the number of points contained in each point set, simplifyingeach point set to obtain simplified target point cloud data. According to the method, the processing efficiency of the point cloud data in the medical image information processing system is improved,and meanwhile, the modeling effect is ensured.

Description

technical field [0001] The present disclosure relates to the technical field of digital medical care, and in particular, relates to a point cloud data reduction method, a point cloud data reduction device, a computer-readable storage medium, and an electronic device. Background technique [0002] In the medical imaging information processing system, 3D reconstruction technology can quickly and comprehensively obtain 3D data information, but there is a large amount of redundant information in the obtained point cloud data. If the point cloud data is directly stored and processed, it will occupy a large number of computers. Memory consumes a lot of time in the process of point cloud reconstruction, which affects the processing efficiency of point cloud data. Therefore, how to simplify the point cloud data, improve the processing efficiency of point cloud data, and ensure the modeling effect has become a technical problem to be solved urgently. [0003] It should be noted that...
