Abstract
A lidar is provided, including: an emitting unit, including a plurality of laser emitters and driving circuits, where the driving circuits are configured to drive the laser emitters to emit detection laser beams for detecting a target object, the emitting unit further includes a compensation unit for a blind region, and the compensation unit for a blind region is configured to cause a target object within a short range of the lidar to receive the detection laser beams and cause reflected echoes to be received by detectors; a receiving unit, including a plurality of detectors, where the detectors are configured to receive echoes of the detection laser beams reflected by the target object and to convert the echoes into electrical signals; and a processing unit, coupled to the receiving unit and configured to receive the electrical signals for calculating the distance and/or reflectivity of the target object.
