Abstract: A distance measurement method. A first electronic device establishes a communication connection to a second electronic device. The first electronic device receives a distance measurement instruction. The first electronic device receives a plurality of groups of sound wave signals sent by a speaker in the second electronic device. Then, the first electronic device determines, based on the plurality of groups of sound wave signals, a sending moment, and a sound wave velocity, a real-time distance between the first electronic device and the second electronic device when each group of sound wave signals are received by the first electronic device. Finally, the first electronic device continuously refreshes and displays the real-time distance between the first electronic device and the second electronic device that is obtained through calculation to improve display precision.

Abstract: A multi-focal plane display system and a device are provided. The multi-focal plane display system includes a laser projection optical engine and a holographic reflection light fusion device. The laser projection optical engine is configured to generate and modulate at least two laser beam groups, and transmit the at least two laser beam groups to the holographic reflective optical fusion device, where each laser beam group corresponds to one displayed image. The holographic reflective optical fusion device is configured to reflect the at least two laser beam groups, where exit pupil locations of the at least two laser beam groups are the same, and displayed images of at least two focal planes are obtained by performing imaging on the at least two laser beam groups by a human eye. A structure of the multi-focus plane display system provided in the embodiments is easy to implement.

Abstract: The present disclosure relates to distance measurement methods, apparatuses, and systems, and readable storage media. An example method incudes: obtaining first offset time and a first moment, where the first offset time is a time difference between a system clock of a first device and a second device, and the first moment is a moment at which the second device sends a distance measurement signal; obtaining a second moment at which the distance measurement signal is received, where the second moment is obtained based on a third moment at which the first device starts to receive the distance measurement signal and a receiving time interval; and obtaining a distance between the first device and the second device based on the first offset time, the first moment, and the second moment.

Abstract: Embodiments of this application disclose a video super-resolution processing method. The method includes: obtaining encoded information of any coding block in a video stream; determining an inter-frame prediction mode of the any coding block based on an inter-frame prediction marker included in the encoded information; determining a super-resolution pixel block of the any coding block based on the inter-frame prediction mode of the any coding block and pixel information of a matched coding block identified by a matched coding block index included in the encoded information; and stitching super-resolution pixel blocks of all coding blocks that belong to a same image frame in the video stream to obtain a super-resolution image. Power consumption can be reduced while an effect of super-resolution processing performed on a single frame of image in a video is ensured, and super-resolution processing delays of any two frames of images in the video can be shortened.
