    • The invention relates to a method for modeling the mandibular kinematics of a patient. Said method includes: acquiring at least one stereoscopic image of the face of the patient by means of a stereoscopic camera; building, from said stereoscopic image, a three-dimensional surface model of the face of the patient; identifying characteristic elements of the face of the patient on said stereoscopic image or on said three-dimensional surface model of the face of the patient; determining reference points, axes, and planes for the face of the patient on said stereoscopic image and on said three-dimensional surface model of the face of the patient, respectively, on the basis of said characteristic elements; obtaining a three-dimensional model of the maxillary dental arch and a three-dimensional model of the mandibular dental arch of the patient; registering the three-dimensional models of the dental arches relative to the reference planes of the three-dimensional surface model of the patient; recording the mandibular kinematics of the patient; and applying said recorded mandibular kinematics to the three-dimensional models of the registered dental arches such as to animate said three-dimensional models.
    • 本发明涉及一种用于建模患者的下颌运动学的方法。 所述方法包括:通过立体相机获取患者面部的至少一个立体图像; 从所述立体图像构建患者面部的三维表面模型; 在所述立体图像上或在患者面部的所述三维表面模型上识别患者面部的特征元素; 基于所述特征元素,分别在所述立体图像上和患者面部的所述三维表面模型上确定患者面部的参考点,轴和平面; 获得患者的上颌牙弓的三维模型和下颌牙弓的三维模型; 将牙弓的三维模型相对于患者的三维表面模型的参考平面进行配准; 记录患者的下颌运动学特征; 以及将所记录的下颌运动学应用于配准的牙弓的三维模型,以使所述三维模型动画化。

    • A method and device for automatic identification of a measurement item. Grayscales of pixel points corresponding to an ultrasonic echo formed due to reflection of an ultrasound signal by a living tissue being detected in a designated cross-section image frame are acquired via an image acquisition module (31); then, at least one measurement item corresponding to the designated cross-section image frame is identified by an identification module (32) on the basis of the grayscales of the pixel points; and, a measurement item parameter of the designated cross-section image frame is measured by a measurement module (33) on the basis of the measurement item identified. Because a measurement item of a designated cross-section can be automatically identified on the basis of the content of a designated cross-section image, obviated is the need for a step in which a user moves a track ball to select a measurement item in an ultrasonic measurement process, thus increasing measurement efficiency.
