Abstract: The present application discloses a method and apparatus for switching between servers in a server cluster. The server cluster includes at least one server for implementing a given service. A specific implementation of the method includes: detecting a number of servers in a standby state in the server cluster; starting at least one server in the server cluster so that the number of servers in the standby state reaches a predetermined number, in response to detecting the number of servers in the standby state being less than the predetermined number; monitoring a master server for providing a service in the server cluster; and selecting a server from the servers in the standby state as a master server to continue to provide the service, in response to detecting the master server being abnormal. This implementation solves the data loss problem caused by an abnormal termination or restart of the master server.

Abstract: A motion compensation method and apparatus applicable to laser point cloud data includes acquiring laser point cloud data of a frame; using an acquisition time of a start point as a target time; interpolating coordinate transformation relations and an end laser point, to obtain coordinate transformation relations of other laser points, and transforming coordinates of the other laser points to the coordinates at the target time. During motion compensation on each frame of laser point cloud data, the coordinate transformation relations corresponding to only the start and end laser points are obtained, and the coordinate transformation relations corresponding to the two points are interpolated to obtain transformation relations corresponding to other laser points, thus performing motion compensation. Therefore, the processing speed is improved and meets high real-time requirements on systems such as autopilot control systems.
