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.
