  • Patent number: 11145234
    Abstract: The present application discloses a screen projecting method, an apparatus, a device and a storage medium. A specific implementation is: receiving a request for screen projecting from a terminal device, where the request for screen projecting includes indication information of content to be screen-projected; acquiring the content to be screen-projected according to the request for screen projecting; receiving a first initiating message of at least one screen projecting source from a target projecting device, and determining a target screen projecting source from the at least one screen projecting source; and sending the content to be screen-projected and an identifier of the target screen projecting source to the target projecting device, where the identifier of the target screen projecting source indicates to the target projecting device to display the content to be screen-projected through the target screen projecting source.

  • Publication number: 20210223046
    Abstract: A method and device for extracting key frames in simultaneous localization and mapping and a smart device. The method includes acquiring an image frame from an image library storing a plurality of image frames of an unknown environment, and performing feature extraction on the image frame to obtain information of feature points, wherein the information includes a quantity of feature points; acquiring relative motion information of the image frame relative to the previous key frame, and calculating an adaptive threshold currently used by using the relative motion information; and selecting a key frame according to the information of feature points and the adaptive threshold indicating space information of image frames.

  • Patent number: 9994775
    Abstract: A process for producing mesophase pitch from high-temperature coal tar comprises: removing salts and quinoline insoluble fraction from a high-temperature coal tar to obtain a decant oil; using the decant oil as a hydrogenation feedstock, or pre-distilling the decant oil to obtain a residue with a boiling point higher than 230 and formulating the residue into a hydrogenation feedstock; catalytic hydrorefining the hydrogenation feedstock to obtain a hydrofined oil; distilling the hydrofined oil to obtain hydrogenated pitch; and subjecting the hydrogenated pitch to the thermal polymerization to obtain the mesophase pitch. The process has features such as an easily controllable degree of hydrogenation, complete removal of impurities, good raw material flowability, not tending to form the carbon deposition and the coking during the process, and not tending to jam the reactor. The product has a high content of mesophase pitch, a low softening point and a low impurity content.
