摘要： D4D-55-PCT PATENT 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. - 15 -

摘要： The present disclosure describes methods, systems, and devices for combining multiple images onto a 3D model. The textures of the images are applied to the 3D model dynamically so that the textured 3D model is viewable from different viewpoints in real time. The present disclosure also describes methods, systems, and devices for selecting the images and portions of the selected images to map to defined areas of the 3D model. In addition, the present disclosure describes how to remove the effects of directional lighting from the images. Some aspects of the present disclosure are particularly useful in the context of dental preparations. In some instances, a 3D digitizer is used to produce 3D models of dental preparations that are rendered on a display in real time and are fully 3D dimensional, while accurately depicting the surface textures of the item(s) being digitized.
摘要翻译：本公开描述了将多个图像组合到3D模型上的方法，系统和装置。图像的纹理被动态地应用于3D模型，使得纹理3D模型可以从不同视角实时观看。本公开还描述了用于选择图像和所选图像的部分以映射到3D模型的定义区域的方法，系统和设备。此外，本公开描述了如何从图像中去除定向照明的影响。本公开的一些方面在牙科制剂的上下文中是特别有用的。在某些情况下，3D数字化仪用于产生实时显示在显示器上并完全3D维度的牙科准备物体的3D模型，同时准确描绘被数字化的物品的表面纹理。
