ABSTRACT
Text-to-logic conversion is studied in a system approach which extracts a conceptual representation of temporal developments within a road traffic scene recorded by a video camera. A Fuzzy Metric Temporal Horn Logic (FMTHL) facilitates a schematic representation of road vehicle behavior at intersections. Geometric results of a model-based vehicle detection and tracking subsystem are used to interpret this generic conceptual FMTHL representation in order to obtain a conceptual description of the specific developments in the recorded traffic scene. One task accepts a natural language (NL) English text formulation of the generic conceptual knowledge and converts this into the internal FMTHL representation. This requires to distinguish algorithmically between discourse-related and scheme-related NL statements. A separate second task creates a synthetic video sequence from a NL text, using as much as possible the same apparatus as the first one. A comparison between genuine road traffic video sequences and those generated synthetically allows to test both the text-to-logic transformation and the use of geometric knowledge represented within the entire system for image sequence evaluation and subsequent interpretation. Results obtained by the execution of both tasks are discussed. |
