A method for generating a UAV flight trajectory. The method includes acquiring map data of a to-be-reconstructed area; the map data includes a satellite map image and a plane map image; acquiring building silhouettes of each building in a to-be-reconstructed area from a plane map image; acquiring height data of each building from a satellite map image; generating an initial model according to the building silhouettes and height data of each building; determining a view set according to an initial model; generating a flight trajectory from a view set. The initial model can be established without pre-flight of the to-be-reconstructed area, and the UAV flight trajectory can be directly generated, so that the calculation amount of data is reduced.

A method to effectively share a message includes: establishing an association relationship between a first electronic device and a device account thereof; controlling the first electronic device to play first multimedia data by using the device account, sending an invitation link to a client corresponding to a second account; receiving, by using the device account, second message data sent by the client corresponding to the second account when the client corresponding to the second account accepts the invitation link; and sending first message data sent by a client corresponding to the first account and received by the device account and the second message data to the first electronic device, so as to display the message data on the first multimedia data.

Message sharing method, client, and computer storage medium

The disclosure provides a data synchronization system, apparatus and method. A primary memory area is created at a destination end apparatus, and an incremental synchronization process is performed. A source end apparatus records a log for a write operation, including operation information and a sequence number for the operation. A latest destination-end write operation sequence number is recorded. The source end pushes in real-time write operation information corresponding to a source-end write operation sequence number greater than the latest destination-end sequence number to the destination end if a latest source-end write operation sequence number is greater than the latest destination-end sequence number. The destination end apparatus performs a write operation on the primary memory area according to the write operation information, records a write operation sequence number of the primary memory area and sends a latest write operation sequence number of the primary memory area to the source end apparatus.
