A LIDAR device having a smart power management system and a method of the LIDAR device implementing the smart power management system

摘要

The lidar device of the present invention is a lidar device having a smart power system, and a laser output unit having a first emitter, a second emitter and a third emitter for outputting a laser, from the first emitter A detector unit including a first detector for detecting the laser output, a second detector for detecting the laser output from the second emitter, and a third detector for detecting the laser output from the third emitter; A controller for controlling the laser output unit and the detector unit, wherein the lidar device operates in at least a first operation mode and a second operation mode that consumes less power per unit time than the first operation mode, the controller When operating the lidar device in the first operation mode, N by operating the first emitter in a first sampling period for acquiring first point data based on the laser output from the first emitter Outputs a laser number (N is a natural number), and operates the second emitter M times (M is a natural number) by operating the second emitter in a second sampling section for acquiring second point data based on the laser output from the second emitter ) output the laser, but setting the first time interval between the first sampling period and the second sampling period, and operating the lidar device in the second operation mode, the output from the first emitter In a third sampling period for obtaining third point data based on the laser, the first emitter is operated to output an L-th laser (L is a natural number), and the second emitter is based on the laser output from the third emitter. In a fourth sampling section for acquiring 4-point data, the third emitter is operated to output a laser P times (P is a natural number), and a second time interval is used between the third sampling section and the fourth sampling section. and the second time interval may be set to be longer than the first time interval.
