Abstract: The present disclosure provides, for example, a lidar ranging method. The method may include calling a sequencer to generate a preset sequence with the sequencer. The method may also include determining a pulse transmission interval of double pulses according to the preset sequence and a preset value. The method may further include transmitting a probing signal to an object to be ranged according to the pulse transmission interval of the double pulses. The method may additionally include receiving, from the object to be ranged, an echo signal returned according to the probing signal. The method may also include extracting a valid echo signal from the echo signal. The method may further include calculating a distance from the object to be ranged according to a time difference between the valid echo signal and the probing signal.
