A Fast and Effective Approach to Lane Marking and Neighboring Vehicles Detections Based on Vision/GPS Sensing Together with Vehicle-to-Vehicle Communication

摘要

A fast warning response to an impending crash based on vision/GPS sensing together with v2v communication has been realized to achieve line marking recognition, neighboring vehicles detection, and headway estimation, where a distributed embedded dual-platform DaVinci+XScale-NAV270 was built to improve system effectiveness as well as a data fusion QT-BPNN/ANFIS was applied to dissolving the heterogeneous data. GPS information for each car was exchanged and disseminated each other via dedicated short range communication (DSRC). It performs at the least response time 0.5972 seconds and gets reduced accident rate about 70~82%, superior to two alternative collision warning systems.
