Abstract: A method for controlling a lidar and a lidar are provided. The method includes: emitting a first sequence of laser pulses, the first sequence of laser pulses including at least a first detection pulse and a second detection pulse coded at a time interval T; receiving a plurality of echo pulses; determining whether an overlay is present among the plurality of echo pulses; and controlling the lidar to emit a second sequence of laser pulses to perform re-detection based on a determination of whether the overlay is present among the plurality of echo pulses.

Abstract: A method, a processor, and a laser radar system for filtering out interstitial points in a radar point cloud includes: for a to-be-recognized point in a point cloud, acquiring, from point cloud information, ranging information of the to-be-recognized point, ranging information of one or more auxiliary points at the first side of the to-be-recognized point, and ranging information of one or more auxiliary points at the second side of the to-be-recognized point; determining, based on the ranging information of the to-be-recognized point, whether the to-be-recognized point is an interstitial point; and filtering out the to-be-recognized point if the to-be-recognized point is the interstitial point.

Abstract: A control method of a lidar is provided. The lidar includes a laser emitter array with N laser emitters. The control method includes: controlling n laser emitters to emit a first detection laser beam, and controlling k laser emitters among the n laser emitters to emit a second detection laser beam; receiving echoes, reflected by a target object, of the first detection laser beam and the second detection laser beam; calculating a distance of the target object according to the echoes; and reducing, in a case that the target object is detected in a preset distance, an emission intensity of the first detection laser beam emitted by at least parts of the n laser emitters in a range corresponding to the target object in a next detection period.
