    摘要: A method of providing communication coverage includes collecting a location of an unmanned aerial vehicle (UAV) while the UAV is flying along a flight path, determining a communication signal distribution in a proximity of the location, determining one or more locations for arranging one or more relays based on the communication signal distribution to improve communication coverage along the flight path, and instructing the UAV to communicate with a user terminal via at least one of the one or more relays when the UAV is determined, based on the communication signal distribution, to be incapable of directly communicating with the user terminal at a predetermined minimum quality level.

    摘要: An image processing method includes obtaining a current image frame. The image processing method also includes in response to feedback information, determining a reference image frame for coding the current image frame based on the feedback information. The feedback information is transmitted by a receiver based on a variable feedback time interval, and is configured to indicate a transmission status of an image frame transmitted by a transmitter to the receiver prior to the feedback information. The image processing method also includes coding the current image frame based on an inter-frame coding and the reference image frame to generate coded data. The image processing method further includes transmitting the coded data to the receiver.

    摘要: A wearable apparatus includes a first display screen having a first display plane, a second display screen having a second display plane, a first optical mirror including a first reflective surface facing the first display screen, a second optical mirror including a second reflective surface facing the second display screen, a first eyepiece arranged between the first display screen and the first optical mirror, and a second eyepiece arranged between the second display screen and the second optical mirror. An optical axis of the first eyepiece is approximately parallel to the first display plane. An optical axis of the second eyepiece is approximately parallel to the second display plane. The first reflective surface and the first display screen form a first predetermined angle. The second reflective surface and the second display screen form a second predetermined angle.
