摘要:
An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device captures images of an object of interest, e.g., patient teeth or associated anatomy, by projecting the light source as a first series of frames, and a second series of frames. The first series of frames projects first pattern data, and the second series of frames projects second data. The second series of frames are interleaved between frames in the first series of frames. The frames in the first series are partially-illuminated and are used to capture data for a 3D model. The frames in the second series are preferably fully-illuminated and are used to generate a live preview of the object. By displaying the live preview frames in juxtaposition to the 3D model, the operator is provided with visual feedback of the object.
摘要(中):
口内扫描装置包括光源和光学系统,并与显示系统通信。 该设备通过将光源投影为第一系列的帧和第二系列的帧来捕获感兴趣对象的图像,例如患者牙齿或相关的解剖结构。 第一系列框架投影第一个模式数据,第二个系列框架投影第二个数据。 第二系列帧在第一系列帧中的帧之间进行交织。 第一系列中的框架是部分照明的,用于捕获3D模型的数据。 第二系列中的帧优选地被完全照明,并且用于生成对象的实时预览。 通过与3D模型并置显示实时预览帧,操作者被提供对象的视觉反馈。
