1. A Lidar system for measuring distances to objects in a 3D environment, the Lidar system comprising:
an emitting module comprising a plurality of lasers that are coupled with a driving circuit and are arranged at different heights along a vertical direction; and
a receiving module comprising a plurality of detectors having one or more single-photon avalanche diodes, the plurality of detectors configured to receive lasers emitted by the emitting module,
wherein each laser is capable of emitting a multi-pulse sequence substantially toward a spot in the 3D environment within a time window having a predetermined duration, and time intervals between two consecutive pulses in the multi-pulse sequence are no longer than 500 ns, and
wherein at least two lasers of the plurality of lasers are configured to emit laser pulses simultaneously.
