Abstract: A communication method for data transmission in the internet of vehicles V2X and a related device. The method includes a first terminal device that receives first information from a first radio access network device, where the first information includes service information of a service of the first terminal device and a resource configuration mode on a sidelink, and there is a correspondence between the service information and the resource configuration mode on the sidelink. The first terminal device transmits, based on the correspondence, data corresponding to the service information on a sidelink transmission resource configured based on the resource configuration mode. The service information may be reliability information.

Abstract: The present disclosure provides a light field imaging system by projecting near-infrared spot in remote sensing based on a multifocal microlens array. The light field imaging system includes a near-infrared spot projection apparatus (100) and a light field imaging component (200), where the near-infrared spot projection apparatus (100) is configured to scatter near-infrared spots on a to-be-observed object to add texture information to a target image, and the light field imaging component (200) is configured to image a target scene light ray with additional texture information. The present disclosure can extend a target depth-of-field (DOF) detection range, and particularly, reconstruct a surface of a weak-texture object.
