Abstract
Systems and methods are provided that implement spatio-temporal query of perception data streams. A system is distinctly designed to implement efficient and flexible spatio-temporal queries, which conduct pattern matching over perception data streams for automotive applications, particularly autonomous vehicles. The system is also designed to enable the spatio-temporal queries to be expressed in SpREs (Spatial Regular Expressions), which is implemented as a querying language that combines the ease of REs (regular expressions) with the enhanced capabilities of spatial logic. Additionally, a method includes receiving a command associated with a spatio-temporal query, wherein the expression comprises spatial regular expressions (SpREs). Thereafter, performing the spatio-temporal query of a plurality of perception data streams using the SpREs, where the SpREs describe spatio-temporal patterns to be searched within the plurality of perception data streams.
