摘要： A scanning module, a detection apparatus, and a terminal device are provided to resolve a problem of low detection accuracy in the conventional technology. This application may be applied to the fields such as autonomous driving, intelligent driving, and assisted driving. The scanning module includes m reflective surfaces that are of a polyhedron reflective component and that are adjacent in a first direction, where m is a positive integer. For a first reflective surface in the m reflective surfaces, the first reflective surface includes n reflective sub-surfaces, and an included angle between two adjacent reflective sub-surfaces is greater than 0° and less than 180°, where n is an even number greater than or equal to 4, and the n reflective sub-surfaces are adjacent in a second direction different from the first direction. Because detection light emitted to two adjacent reflective sub-surfaces is converged after being reflected by the two reflective sub-surfaces, a size of a light spot of the detection light reflected by the scanning module can be reduced, to reduce or even eliminate stray light reflected by another mechanical part or the like due to a large size of the light spot of the detection light, so that accuracy of the detection apparatus using the scanning module can be improved.

摘要： A camera compact module installation method and a mobile platform are provided, and are used for autonomous driving or intelligent driving. The method includes: installing a camera compact module on a mobile platform, where the camera compact module is parallel to a ground on which the mobile platform is located. The camera compact module includes a lens group and an image sensor, and the lens group includes at least one lens. A projection of a center of the lens group on a plane of the image sensor is a first position. A distance between the first position and a center of the image sensor is greater than a first threshold, and the first threshold is greater than 0. In this way, because the camera compact module can be parallel to the ground on which the mobile platform is located, it can be ensured that a motion direction is perpendicular to the plane of the image sensor. This can improve accuracy and robustness of camera motion estimation, to reduce a target positioning error. In addition, a required detection range can be met without tilting the camera compact module for installation. The method may be applied to the internet of vehicles, for example, vehicle-to-everything V2X, long term evolution-vehicle LTE-V, or vehicle-to-vehicle V2V.

摘要： This application provides a circuit board reinforcing structure, a photosensitive apparatus, and a terminal. The photosensitive apparatus may be used in assisted driving, intelligent driving, or autonomous driving. In the circuit board reinforcing structure, a reinforcing plate of which deformation varies little with temperature is used to suppress warping and deformation of a circuit board caused by a temperature change, so that an impact of the warping and deformation of the circuit board on a location of a photosensitive chip is greatly reduced. In addition, the reinforcing plate and the photosensitive chip are disposed on a same side of the circuit board, so that when the circuit board reinforcing structure is used in the photosensitive apparatus, a wire can be conveniently led out from the circuit board without disposing an additional structure for wiring on the reinforcing plate. Further, the photosensitive apparatus including the circuit board reinforcing structure in this application and the terminal have same effect.

摘要： A data transmission method, an apparatus, and a network system are used to transmit CPRI data in the Ethernet, and can support CPRI data corresponding to multiple service flows to be exchanged between multiple RRUs and multiple BBUs in any network by using an existing switching device from point to point, point to multipoint, and multipoint to multipoint. This not only reduces CPRI networking costs, but also improves CPRI networking flexibility. A specific implementation method includes: receiving, by a sending apparatus, CPRI data, where the CPRI data includes CPRI data of at least one service flow; parsing out, from the CPRI data, a CPRI data payload corresponding to each service flow, and separately encapsulating, based on a dedicated processing frame header of each service flow, the CPRI data payload of the corresponding service flow, to obtain a packet of each service flow, where the dedicated processing frame header includes a service flow identifier corresponding to the service flow; and transmitting the packet of each service flow to a receiving apparatus.
