  • 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: 10922825
    Abstract: An image data processing method is provided for a mobile terminal. The method includes receiving by a first electronic device first image data of an environment collected by a second electronic device; determining one or more motion parameters of the second electronic device based on the first image data; determining a latency between a moment the first image data being transmitted by the second electronic device and a moment the first image data being received by the first electronic device; compensating the first image data based on the one or more motion parameters of the second electronic device and the latency as determined, to generate second image data; and displaying the second image data through the first electronic device.
