Title:
MULTIPLE LIDAR SYSTEM AND DRIVING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/031701
Kind Code:
A1
Abstract:
A communication and control measurement technology is disclosed. That is, a multiple LiDAR system and a driving method thereof, according to the embodiments of the present invention, perform 3D modeling extraction by using first and second laser beams and simultaneously inject the first and second laser beams to objects or people to be perceived and measured so as to analyze and display first and second image detection signals returned back at each angle, wherein only the laser beam, which the system is to receive, among the first laser beam including a first communication code and the second laser beam including a second communication code, both of which have already been emitted, is accurately identified through a communication code comparing and matching process, and object recognition information or human recognition information extracted therefrom is clearly displayed, thereby maximally suppressing an interference phenomenon or a noise phenomenon which can be caused by collision due to signal overlap between the respective laser beams since communication codes are differently assigned even if multiple LiDAR systems are simultaneously operated.
