Embodiment Construction
[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0055] The present invention provides a breast point cloud segmentation method, the purpose of which is to collect three-dimensional point cloud data according to the chest area of each user, and extract the point cloud corresponding to the breast area to be scanned from the original three-dimensional point cloud data, and pass the points The location information represented by the cloud formulates an ultrasound scanning trajectory, so that the breast ultrasound scanning device can perform a scanning process according to the ultrasound scanning trajectory, and then generate a comprehensive and accurate ultrasound image.
[0056] Such as figure 1 As shown, in order to provide an environmental basis for the implementation of the method, the aforementioned breast ultrasound scanning equipment mainly includes a scanning...

The invention discloses a breast point cloud segmentation method, which includes: obtaining three-dimensional point cloud data; deleting the point cloud corresponding to the bed plane area from the three-dimensional point cloud data according to preset conditions to obtain the chest area point cloud; Calibrate to determine the segmentation boundary on the upper side of the chest and the central segmentation boundary; construct the horizontal tangent plane upwards according to the preset height increment value until the point cloud on the horizontal tangent plane satisfies the boundary segmentation conditions, then fit the point cloud on the current horizontal tangent plane Form the axillary segmentation boundary; construct the lower chest segmentation boundary according to the upper chest segmentation boundary; extract the point cloud of the chest scan area. The technical solution of the present invention can quickly and accurately segment the point cloud of the breast area to obtain three-dimensional spatial information of the breast area, thereby providing a basis for subsequent scanning trajectory planning.
Description
technical field [0001] The present invention relates to the technical field of point cloud data processing, in particular to a breast point cloud segmentation method, device, storage medium and computing equipment. Background technique [0002] Ultrasound examination, a non-surgical diagnostic examination, is painless, non-invasive, and non-radioactive to the subject. Moreover, ultrasound can clearly display various cross-sectional images of internal organs and their surroundings. Since the images are full of solidity and close to the real anatomical structure, the application of ultrasound examination can make an early diagnosis. Based on the many advantages of ultrasonography, from professional medical disease diagnosis to daily health indicator assessment, its application range is becoming wider and wider. [0003] With the development of medical diagnostic technology and the improvement of economic level, more and more women begin to pay attention to breast health, and ...
