A distance measurement method, a distance measurement device (40), a system, and a computer readable storage medium. The method comprises: sequentially performing measurement for different directions to be measured, comprising, when measurement is performed for a first direction, the first direction being one of the directions to be measured, continuously transmitting at least two light pulses to the first direction, pulse parameters of different light pulses being different, and the pulse parameter comprising transmit power or the maximum amplitude; receiving at least part of an echo signal of each of the at least two light pulses; and obtaining the distance of an object to be measured in the first direction according to the pulse parameter of at least one of the at least two light pulses and the at least part of an echo signal of at least one of the at least two light pulses. Light pulses having different transmit power or the maximum amplitudes can measure different distances, such that effective measureme
