Abstract

The invention discloses a method and system for generating a subway environment target training set. A game confrontation generation network is used to automatically generate possible obstacles into the natural environment of rail transit by learning the characteristics of normal objects in urban rail transit. At the same time, a decision network is used to distinguish generated data from real data. Through the game process of generative network and decision network, the real simulation of urban traffic obstacles is realized, and the target training set of subway environment is obtained. The accuracy of target training can be improved by adopting the present invention.

Description

technical field [0001] The invention relates to the field of subway traffic, in particular to a method and system for generating a subway environment target training set. Background technique [0002] Due to the complex environment in the subway, a wide range of illumination conditions, and many types of targets, the device is installed on a moving train, which is difficult to detect with traditional background-based learning or morphological methods. The artificial intelligence target training method requires a large number of data sets to support, and the installation conditions of the subway train restrict the computing power of the underlying processing platform, making it difficult to use a large-scale network with strong generalization ability for training. The target training set is especially important to improve the accuracy of target training. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for generating...
