Abstract: The present application discloses a visual enhancement method and a system based on fusion of spatially aligned features of multiple networked vehicles. The method utilizes the visual features of networked vehicles themselves and their surroundings within a certain range, and performs feature fusion after spatial alignment to realize visual expansion and enhancement. After receiving the compressed intermediate feature map of the networked vehicles in a certain range around, the decompressed intermediate feature map is subjected to affine transformation, and the transformed aligned feature map is subjected to feature fusion based on a designed multi-feature self-learning network, so as to realize the complementation and enhancement among features while removing redundant features. The fused intermediate features are used to detect the target obstacles from the perspective of the networked vehicle itself and partially or completely blocked., thus improving the safety of driving connected vehicles.

Abstract: The present disclosure discloses an autonomous vehicle remote control apparatus and a method based on heterogeneous networks. The apparatus comprises a vehicle information acquisition module, a first message sending module, a first message receiving module and a first remote control module. According to the present disclosure, the possibility of failure of remote control is avoided or greatly reduced by bypassing the area where the network quality does not support remote control when planning a vehicle path, heterogeneous network resources are reasonably utilized on the vehicle driving path, the real-time performance of obtaining vehicle-related information by a remote control terminal is improved, and the availability and reliability of remote control and the safety of vehicle driving are effectively enhanced.

Abstract: A multi-user flexible Ethernet fine granularity time slot allocation method and apparatus. The method is specifically: providing two time slot resource allocation and deployment schemes according to user demands, where the first scheme performs time slot allocation based only on an objective of global minimization of jitter of time slot allocated to all the users and can improve resource allocation equity and improve whole performance of a network. The second scheme performs weighted sum of delay and jitter minimization based time slot allocation on each user according to the quantity of time slots required for the users in sequence from large to small on the premise of most user input data in the current time slot assignment period being transmitted in the current time slot assignment period.
