The invention relates to a pulse
laser distance measurement system and method based on waveform
time domain registration analysis. The
system comprises a
software part and a hardware part, wherein the
software part comprises a communication
software body, a waveform
time domain registration analysis
algorithm, a
multiple echo algorithm and a distance and
reflectivity algorithm. The
distance measurement method includes the steps that in a
control circuit, a
control signal is input, and pulses are sent to a
laser emitter; if the selected emitter only emits one path of lasers, the lasers are emitted to a
beam splitter through a collimating mirror and divided into two beams, one path of the lasers enters a
detector a through an
optical attenuator, and the other path of the lasers is emitted to a target through a convex lens; if the selected emitter emits two paths of the lasers, one path of the lasers directly enters the
detector a, and the other path of the lasers is emitted to the target through the convex lens; target reflection lasers are emitted to a
detector b through the convex lens and an
optical filter, the detector b converts
laser echoes into analog signals, the two paths of analog signals are converted into digital signals on an AD converter through an analog amplification circuit respectively, waveform
time domain registration analysis is conducted in an analysis module, and then the
distance measurement result is output by the
control circuit.
