Title:
LASER RADAR SYSTEM AND DISTANCE MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/107528
Kind Code:
A1
Abstract:
Disclosed are a laser radar system and a distance measurement method. A distance measurement laser signal and at least one redundancy check light signal, being different in terms of feature attributes, are transmitted to a detector (4) via a laser transmitting system (1); a laser receiving system (2) receives a laser signal reflected by the detector in a diffused manner; and a main control system (3) calculates, according to a time difference between laser signal transmitting and receiving, feature attribute information about all light signals of the distance measurement laser signal and at least one redundancy check light signal, and compares and checks same. The laser radar system and the distance measurement method can not only determine whether each piece of measurement data is interfered with, but can also obtain redundancy distance measurement data by using a redundancy check light signal, thereby ensuring the accuracy and reliability of measured data.
