Abstract: Disclosed is a fundus camera, which relates to the technical field of medical devices and includes: an illumination module, a main optical assembly, a focusing module, and an image sensing acquisition module; the illumination module includes a plurality of light sources configured to emit light of different wavelengths, illumination light emitted by the plurality of light sources is conducted to enter an eye of a patient through the main optical assembly, and light reflected by a retina of the patient is conducted to pass through the main optical assembly and the focusing module to enter the image sensing acquisition module. The fundus camera provided by the present application improves the technical problem that the fundus camera in the prior art cannot image different layers of the retina, thereby providing valuable medical and diagnostic data.

Abstract: A virtual robot image presentation method and an apparatus are provided to improve virtual robot utilization and user experience. In this method, an electronic device generates a first virtual robot image, and presents the first virtual robot image. The first virtual robot image is determined by the electronic device based on scene information. The scene information includes at least one piece of information in first information and second information, the first information is used to represent a current time attribute, and the second information is used to represent a type of an application currently running in the electronic device. According to the foregoing method, in a human-machine interaction process, virtual robot images can be richer and more vivid, so that user experience can be better, thereby improving virtual robot utilization of a user.

Abstract: Geologic modeling methods and systems may use design-space to design-space mapping to facilitate simulation grid generation for multiple interpretations of a subsurface region. As one example, one or more embodiments of a geologic modeling method may comprise: obtaining first and second geologic models having different structural interpretations of a subsurface region; mapping each of the geologic models to associated design space models representing an unfaulted subsurface region; determining a design-to-design space mapping from the first design space model to the second design space model; using said mapping to copy parameter values from the first design space model to the second of the design space model; gridding each of the design space models to obtain design space meshes; partitioning cells in the first and second design space meshes along faults; reverse mapping the partitioned design space meshes to the physical space to obtain first and second physical space simulation meshes.
