Abstract: The current document is directed to methods and systems for monitoring a dental patient's progress during a course of treatment. A three-dimensional model of the expected positions of the patient's teeth can be projected, in time, from a three-dimensional model of the patient's teeth prepared prior to beginning the treatment. A digital camera is used to take one or more two-dimensional photographs of the patient's teeth, which are input to a monitoring system. The monitoring system determines virtual-camera parameters for each two-dimensional input image with respect to the time-projected three-dimensional model, uses the determined virtual-camera parameters to generate two-dimensional images from the three-dimensional model, and then compares each input photograph to the corresponding generated two-dimensional image in order to determine how closely the three-dimensional arrangement of the patient's teeth corresponds to the time-projected three-dimensional arrangement.
Abstract translation: 目前的文件是针对在治疗过程中监测牙齿病人进展情况的方法和系统。 患者牙齿的预期位置的三维模型可以及时地从开始治疗前准备的患者牙齿的三维模型投射出来。 数码相机用于拍摄患者牙齿的一个或多个二维照片，这些照片被输入到监视系统。 监视系统根据时间投影的三维模型确定每个二维输入图像的虚拟摄像机参数，使用确定的虚拟摄像机参数从三维模型生成二维图像，然后进行比较 每个输入照片到相应的生成的二维图像，以便确定患者牙齿的三维布置对应于时间投影的三维布置的接近程度。
