摘要： The present application discloses a LiDAR controlling method and device, an electronic apparatus, and a storage medium. The method includes: in a measurement period, determining an emitting group to be started in the measurement period from a laser emitting array, where the emitting group includes at least two emitting units, and physical positions of the at least two emitting units meet a condition of no optical crosstalk; controlling the at least two emitting units to emit laser beams asynchronously based on a preset rule; controlling a receiving unit group of the laser receiving array corresponding to the emitting group to receive laser echoes, where the laser echoes refer to echoes formed after the laser beams are reflected by a target object; and when at least two emitting groups are determined in the measurement period, controlling the emitting groups to emit the laser beams asynchronously based on the preset rule.

摘要： This application discloses a LiDAR, a mobile device, and a LiDAR attachment detection method, where the LiDAR includes a transceiving assembly, a window, a detection module, and a control module. The transceiving assembly is configured to emit an outgoing beam and receive an echo beam. The window is mounted on an optical path corresponding to the transceiving assembly, where part of the outgoing beam emitted by the transceiving assembly forms a reflected beam after being reflected by the window, and the reflected beam includes a specular reflected beam. The detection module is configured to receive the reflected beam and generate a corresponding electrical signal. The control module is electrically connected to the transceiving assembly and the detection module, where the control module is configured to determine whether there is an attachment on the window based on the corresponding electrical signal.
