Abstract

A method and an apparatus pertaining to generating training data are provided. The method may include executing a simulation process. The simulation process may include traversing one or more virtual sensors over a virtual driving environment defining a plurality of lane markings or virtual objects that are each sensible by the one or more virtual sensors. During the traversing, each of the one or more virtual sensors may be moved with respect to the virtual driving environment as dictated by a vehicle-dynamic model modeling motion of a vehicle driving on a virtual road surface of the virtual driving environment while carrying the one or more virtual sensors. Virtual sensor data characterizing the virtual driving environment may be recorded. The virtual sensor data may correspond to what an actual sensor would produce in a real-world environment that is similar or substantially matching the virtual driving environment.

Description

technical field [0001] The present invention relates generally to vehicle systems, and more particularly to methods and systems for generating training data suitable for developing, training, testing and validating algorithms for detecting lane boundaries in a driving environment. Background technique [0002] Well-proven algorithms for interpreting sensor data are indispensable in order to provide, enable, or otherwise support functions such as driver assistance, controlling vehicle dynamics, and / or autonomous driving. In particular, algorithms for detecting the boundaries of driving lanes are crucial. Currently, such algorithms rely on real-world sensor data for development, training, testing, and validation. However, obtaining large amounts of useful real-world data is expensive in terms of time, money, and resources. Contents of the invention [0003] According to the present invention, a method is provided, comprising: [0004] A virtual driving environment is gene...
