Fetus panorama display instrument based on ultrasonic and 3D technology

Abstract

The invention discloses a fetus panorama display method based on an ultrasonic and 3D technology. The method comprises the following steps of image or data obtaining, wherein cross-section image sequences of a fetus are obtained through a B-mode ultrasound probe; image preprocessing and segmenting, wherein the image sequences are subjected to operations like image strengthening, filtering and noise reduction, and a three-dimensional division method based on a maximal interclass variance method is adopted to automatically segment an image area of the fetus; surface reconstruction of a three-dimensional object, wherein according to the preprocessed image sequences, a slice-based method of using a two-dimensional profile line to reconstruct a three-dimensional shape is adopted for three-dimensional reconstructing, and meanwhile, the sex characters of the fetus are removed; arm motion identification, wherein an MYO armlet is utilized to identify the arm motion like leftward motion, rightward motion, upward motion and downward motion, and thus the operations like rotating and turning of the built three-dimensional model can be controlled. An OpenGL is adopted for displaying the reconstruction result, and the three-dimensional model is operated through the further utilization of the identification result of a wristband. By means of the fetus panorama display method based on the ultrasonic and 3D technology, the arm motion identification is applied to 3D panorama displaying of the fetus, and the three-dimensional interaction result can be more visual and convenient.

Description

Technical field [0001] The invention belongs to the technical field of arm motion recognition and control 3D model technology, and particularly relates to a fetal panoramic display method based on ultrasound and 3D technology. Background technique [0002] At present, two-dimensional B-ultrasound is the most commonly used in hospital B-ultrasound. The output is a tomographic image, which is only suitable for professional inspection and analysis. It is not intuitive enough for parents to construct the overall image concept of the fetus. However, most of the models created by 3D B-scanning are performed by clicking and dragging the mouse on the screen to perform operations such as rotation. The human-computer interaction effect is relatively poor, and the interactive interface is relatively unfriendly. [0003] Myo armband is a control terminal device launched by Canadian Thalmic Labs in early 2013. It contains a nine-axis inertial sensor unit, 8 surface EMG sensors and a Bluetooth...
