Systems and methods for LiDAR detection

A method for detection by a LiDAR system, comprising:

• synchronizing a central LiDAR device configured to detect an object at or beyond a first predetermined distance from the LiDAR system, and at least one of an even number of multiple auxiliary LiDAR devices configured to detect an object at or within a second predetermined distance from the LiDAR system, wherein:
• the synchronizing comprises configuring the central LiDAR device and the at least one of the auxiliary LiDAR devices to start to scan at a same time or to match each other's scanning pattern;
• the LiDAR system comprises a mounting apparatus configured to mount the central LiDAR device and the auxiliary LiDAR devices;
• the central LiDAR device is mounted to the mounting apparatus on a first mounting surface of an upper part of the mounting apparatus, and each of the auxiliary LiDAR devices is mounted, via a base, to the mounting apparatus on a second mounting surface of a lower part of the mounting apparatus;
• the base comprises a first LiDAR device base and a second LiDAR device base, each of the first and second LiDAR device bases comprises a LiDAR device holder and a frame disposed on an end of an upper surface of the lower part of the mounting apparatus, and each LiDAR device holder of the first and second LiDAR device bases is adjustably connected to each frame of the first and second LiDAR device bases;
• and
• the first mounting surface and the second mounting surface form an angle, and the upper part and the lower part are at different heights in the mounting apparatus;
• receiving, by the central LiDAR device, a first data frame;
• receiving, by the auxiliary LiDAR devices, a plurality of second data frames;
• combining, by a processor, the first data frame and at least one of the plurality of second data frames;
• generating, by the processor, a first combined data frame;
• and
• identifying, by the processor, a first target object from the first combined data frame.
