## 特征比对表格

技术特征描述及公开性判断结果对比文件原文引用公开性论述
**技术特征A《直接公开》**[2] “Another aspect of the present invention is a capture and encoding subsystem used in an interactive television system... comprising: means for generating video signals indicative of multiple views of the objects within the live-action space; means for processing the video signals to generate data indicative of a geometric structure and colors of the objects;”<br>[2] “Another aspect of the present invention is a rendering system used in an interactive television system providing viewer selectable virtual positions for experiencing an event occurring in a three-dimensional space, wherein the rendering subsystem comprises: ... means for receiving ... video information associated with the event ... and generating in response thereto, display signals ... relative to the virtual position;”对比文件公开了用于交互式电视系统的渲染子系统,其接收与事件相关的视频信息(相当于复合图像)以及场景的几何结构数据(相当于场景结构图),并基于此生成相对于虚拟位置的显示信号(相当于合成图像)。因此,本领域技术人员能毫无疑义地得出,该渲染子系统“基于复合图像及场景结构图而产生合成图像”。
**技术特征B《隐含公开》**[2] “In a parallel path, steps 1112 and 1114 respectively show that the audio signal from each ambient microphone... is also received, sampled, and digitized; and step 1116 shows the ambient audio data from each of the ambient microphones is also divided into a sequence of ambient data chunks.”<br>[2] “The viewer's viewing experience of the live action event is enhanced... The data stream can then be transmitted "live" to remote viewers and/or stored on storage media for later transmission...”对比文件明确其系统可处理实时数据流或存储的数据流。在视频方面,其渲染子系统需要利用先前捕获和编码的视频数据(例如背景数据或关键帧)来构造当前视图。本领域技术人员可以理解,为生成合成图像,系统必须使用先前已处理(即经解码)的一幅或多幅图像(例如背景图像或前一时刻的图像)来构造复合图像。因此,该特征被隐含公开。
**技术特征C《直接公开》**[2] “Another method includes generating, before commencement of the live-action event, encoded data indicative of the locations, shapes, surface geometries, and colors of the non-moving background objects... and generating, during the live-action event, encoded data indicative of the locations, shapes, surface geometries, and colors of the live-action objects...”<br>[2] FIG. 14A 及相关描述说明视频数据块包含背景数据(B)或前景数据(F)。对比文件明确区分并生成两种数据:一种是事件开始前生成的关于非移动背景对象的编码数据(相当于先前经解码图像的场景结构图),另一种是事件期间生成的关于实时动作对象的编码数据(相当于当前图像的场景结构图)。渲染系统会使用这些数据来渲染图像。因此,本领域技术人员能直接且毫无疑义地得出,所使用的场景结构图可以是当前图像的或先前图像的。
**技术特征D《直接公开》**[2] “A triangle mesh includes a set of triangles in 3-D space... represented by a data structure comprising a list of 3-D vertices...”;<br>[2] “In step 5106, each camera pair's dedicated processor ... computes a depth function Z(p) including depth values Z(px) for pixels p in the left image...”;<br>[2] “The vertices data 916-1 includes, for each mesh, a set of vertices specified in world coordinates...”对比文件详细描述了如何从立体图像对计算深度,并生成由三维顶点列表(即三维点)表示的三角形网格。这些顶点的世界坐标(x, y, z)明确指示了它们在场景中的位置,而深度值Z(p)直接指示了相对深度。因此,该技术特征被对比文件直接公开。
**技术特征E《直接公开》**[2] “The viewer input processor 310 generates signals 311 indicative of a viewer selected, current virtual viewpoint, and provides the signals 311 to both the video rendering subsystem 306 and the audio rendering subsystem 308 so that the two rendering subsystems render a 3-D experience to the viewer from his or her selected virtual viewpoint.”<br>[2] “The video rendering subsystem 306 ... estimates from such information, the right-eye and left-eye 2-D images that a viewer would see if actually located at the position and orientation of the current virtual viewpoint...”对比文件中的渲染子系统接收表示当前虚拟视点的信号(包括位置和定向),并基于此渲染出左右眼图像。这意味着渲染合成图像时,完全利用了当前虚拟视点的摄像机位置及定向信息,且渲染出的图像正是从该视点观察的结果。因此,该特征被直接公开。
**技术特征F《直接公开》**[2] “A triangle mesh includes a set of triangles in 3-D space having the property that each triangle shares a common edge with at least one other triangle in the set. A triangle mesh is preferably represented by a data structure comprising a list of 3-D vertices, together with connectivity information giving, for each triangle in the mesh, a list of the indices... of its vertices.”<br>[2] 图11C及对应描述展示了像素点被互连形成三角形网格。对比文件的核心技术之一就是生成并利用三角形网格来表示场景的代理几何结构。该网格通过连接(互连)三维顶点(点)而形成。这完全公开了“互连所述场景结构图的点以形成代理几何结构”这一技术特征。
**技术特征G《直接公开》**[2] “In step 2803, the right renderer 2302 reads from shared memory the camera-pair identifier N associated with the triangle retrieved in step 2801. It then maps color information from the decompressed 2-D data for camera pair N stored in the shared memory 2309, onto the retrieved triangle.”<br>[2] “Conventional texture mapping techniques are used for coloring and patterning the triangle using the 2-D color information obtained in step 2803.”对比文件详细描述了渲染过程:将来自特定摄像机对的解压缩2-D颜色信息(相当于复合图像)映射(纹理映射)到检索到的三角形(即代理几何结构的一部分)上,从而形成基于图像的模型。这直接公开了该技术特征。
**技术特征H《直接公开》**[2] “The video rendering subsystem 306 ... estimates from such information, the right-eye and left-eye 2-D images that a viewer would see if actually located at the position and orientation of the current virtual viewpoint at the selected live action event.”<br>[2] “The right renderer 2302 renders the triangle into the right-eye frame buffer 2304 from the perspective of a right-eye image...”对比文件中的渲染子系统(右渲染器和左渲染器)执行渲染过程,将基于图像的模型(纹理映射后的三角形网格)转换为最终显示的二维图像(即合成图像)。这直接对应于“渲染所述基于图像的模型以产生所述合成图像”。
**技术特征I《未公开》**无相关内容。目标专利中的“残差图像”是指当前图像与合成预测图像之间的差异,用于视频编码中的残差编码。对比文件所描述的虚拟现实电视系统旨在从任意视点合成新视图,其渲染过程是直接生成最终显示图像,并非作为预测图像,也不计算当前捕获图像与合成图像之间的差异(残差)。因此,对比文件既未直接公开也未隐含公开“确定残差图像”这一特征。
**技术特征J《未公开》**无相关内容。由于对比文件未公开“残差图像”(特征I),因此也就不存在基于残差图像和合成图像来重构当前图像的技术方案。该特征未被公开。
**技术特征K《未公开》**无相关内容。该特征与“确定残差图像”相关,是特征I的一部分。如上所述,对比文件未涉及残差图像的概念,因此也未公开接收残差图像。
**技术特征L《直接公开》**[2] “In step 2803, the right renderer 2302 reads from shared memory the camera-pair identifier N associated with the triangle retrieved in step 2801. It then maps color information from the decompressed 2-D data for camera pair N stored in the shared memory 2309, onto the retrieved triangle.”<br>[2] “The camera information is preferably provided in special type video data chunks ... and stored ... in the shared memory 2309...”对比文件明确说明,在纹理映射时,渲染器会使用与三角形相关联的摄像机对信息。该摄像机对信息包含了摄像机的位置和定向。这相当于基于一或多个先前经解码图像(即用于纹理的2D数据对应的图像)的摄像机位置及定向信息来执行纹理映射。因此,该特征被直接公开。
**技术特征M《直接公开》**同特征L引用内容。此特征与特征L表述完全一致,基于相同的对比文件内容,因此同样被直接公开。
**技术特征N《直接公开》**同特征L引用内容。此特征与特征L、M表述完全一致,基于相同的对比文件内容,因此同样被直接公开。
**技术特征O《直接公开》**[2] “The control processor 304 receives the data stream from the distribution subsystem 20. It extracts the audio chunks and video chunks from the data stream, and sends them to the audio rendering 308 and the video rendering subsystem 306 respectively.”<br>[2] FIG. 14A 展示了视频数据块包含网格描述符(顶点数据和连接数据)。对比文件中的数据流包含视频数据块,这些数据块中包括了网格数据(即场景结构图信息)。渲染子系统接收这些数据流并提取其中的视频块(包含网格数据)。这直接对应于“接收所述当前图像的所述场景结构图的信息”。虽然未明确提及“指示...差异的信息”,但接收场景结构图信息已被直接公开。
**技术特征P《直接公开》**[2] “The left renderer 2303 reads mesh data ... and in step 2714 stores such data in the shared memory 2309.”<br>[2] “In a first step 2801, the right renderer 2302 retrieves a triangle from the mesh data stored in the shared memory 2309.”对比文件描述了渲染器从数据流中读取网格数据(场景结构图信息)并存储,然后在渲染时从存储器中检索这些数据用于产生合成图像。这直接公开了“基于所述所接收信息而产生所述场景结构图,其中产生所述合成图像包括:基于所述复合图像及所述所产生场景结构图而产生所述合成图像”。
**技术特征Q《直接公开》**[2] “The camera information is preferably provided in special type video data chunks ... and stored ... in the shared memory 2309, so as to be accessible to both the left and right renderers...”<br>[2] “The viewer input processor 310 generates signals 311 indicative of a viewer selected, current virtual viewpoint...”对比文件说明,用于纹理映射的摄像机信息(位置和定向)通过特殊数据块提供并存储,供渲染器使用。同时,当前虚拟视点(相当于当前图像的摄像机位置及定向)由输入处理器生成并提供给渲染器。渲染器在纹理映射和渲染过程中会使用这些信息。因此,该技术特征被直接公开。
