  • Patent number: 10994419
    Abstract: A method, system, and one or more computer-readable storage media for controlling a robot in the presence of a moving object are provided herein. The method includes capturing a number of frames from a three-dimensional camera system and analyzing a frame to identify a connected object. The frame is compared to a previous frame to identify a moving connected object (MCO). If an unexpected MCO is in the frame a determination is made if the unexpected MCO is in an actionable region. If so, the robot is instructed to take an action.

  • Patent number: 10970913
    Abstract: Disclosed is a hybrid approach to rendering transparent or translucent objects, which combines object-space ray tracing with texture-space parametrization and integration. Transparent or translucent objects are first parameterized using two textures: (1) a texture that stores the surface normal at each location on the transparent or translucent object, and (2) a texture that stores the world space coordinates at each location on the transparent or translucent object. Ray tracing can then be used to streamline and unify the computation of light transport inside thick mediums, such as transparent or translucent objects, with the rest of the scene. For each valid (e.g., visible) location on the surface of a transparent or translucent object, the disclosed embodiments trace one or more rays through such objects and compute the resulting lighting in an order-independent fashion. The results are stored in a texture, which is then applied during the final lighting stage.

  • Patent number: 10964094
    Abstract: System that transforms 2D images of slices of an object, such as a tissue sample from a biopsy, into a 3D point cloud for visualization. 3D points may be generated for pixels in the 2D images with high luminance. Point depths may be assigned pseudo-randomly so that the points fill the space within the slice. The probability distribution for the random depths may be based on any characteristics of the 2D images. For example, points corresponding to pixels within large areas of high luminance may be spread relatively uniformly through the slice, while isolated points or points in small areas may be biased towards the minimum depth of the slice. Points in the point cloud may be partitioned into channels, corresponding for example to different stains of a sample, and may be visualized for example as different color assigned to points.

  • Patent number: 10952795
    Abstract: As part of a real-time three-dimensional (3D) cardiac imaging system and method, anatomical data of a cardiac structure may be acquired and a 3D model of the cardiac structure may be generated. Visual data relevant to a cardiac procedure may be generated, such as location and orientation of a catheter, tags, points, color-coded temperature information, and/or color-coded local activation times (LAT) for the cardiac structure. The visual data superimposed on the 3D model of the cardiac structure may be visually displayed on a visual display device. A glass state view may be generated by generating a modified set of the visual data that includes removing at least a portion of the visual data that obscures a view of an anatomical feature of interest and/or the catheter, and adding edge enhancement to the cardiac structure. The glass state view may be requested to be visually displayed on the visual display device.
