Abstract

The invention relates to a data processing method and system based on a neural network, and relates to the field of intelligent transportation. The method comprises the steps that according to map data of a first area, an input feature vector of a neural network is constructed, and the map data comprises roadside information, distance information, road information and receiving information; constructing a training set, a verification set and a test set based on historical data; constructing a shallow neural network model; training, verifying and testing the shallow neural network model to generate a final neural network model; and integrating the neural network model to an automatic driving controller, and determining first information related to the map data. According to the data processing method and system based on the neural network, on the basis of multi-dimensional information such as access time, frequency, road characteristics and RSU distribution characteristics, data processing priority ranking is more reasonable, cache resources are effectively released, and the purpose of storing map data actually needing to be cached is achieved.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a neural network-based data processing method and system. Background technique [0002] In an automatic driving or vehicle-road coordination system, the automatic driving controller at the vehicle end needs to process high-precision map information. For general vehicle navigation, the high-precision map data volume is huge, and the storage capacity is several orders of magnitude higher. If it is completely dependent on the vehicle automatic driving controller, it is impossible to achieve persistent storage of high-precision map information. [0003] In the vehicle-road coordination system, the roadside unit RSU can broadcast map MAP data to the self-driving vehicle, and the MAP cache is a common method for the self-driving vehicle terminal to solve the problem that the high-precision map data cannot be persisted. In the prior art, all the map information data ...
