In 2019, Huawei applied for patents related to lidar technology in China. Now, on March 5, the company has published the two patents with publication number CN112444818A and CN112446270A named a kind of lidar and identification method and device for pedestrian re-recognition network.

The lidar is instantly required to solve some complex situations such as non-standard roads, non-standard pedestrians, and non-standard driving behavior in urban areas.

The Patent describes that these innovations can be used in autonomous driving and connected vehicles. It includes laser, first sub-terminal module, generator, main tube coherent detection module, modulation processing control module.

The laser is used to transmit the emitted laser beam to the first sub-meter module. The first sub-meter module is used to divide the laser into standard light and light, and the intrinsic light is transmitted to the tube coherent detection module.

The modulator is used to modulate the light, and the modulated signal light is transmitted to the three-ring area, and the three-street coherent detection module is used to receive the echo light signal, Intrinsic light, and reference electrical signals. The optical transmission has three modulators and the generator transmits the reference electrical signal to the three-level coherent detection module and the modulated electrical signal to the three-modulator.

According to the echo light number, intrinsic light, and reference signal coherent detection, determines the target standard and transmits to the three processing control modules. The processing control module is used to determine the target object-related information according to the target electrical signal. It can improve the sensitivity of disassembly.
