Abstract:
1. An image-based barrier detection and warning system comprising: at least one image capture unit capturing a road image; at least one processing device electrically connected with said image capture unit, detecting a horizon and defining ROI-H (Region Of Interest-Height) according to a vanishing point proximate the detected horizon to establish a horizontal line signal according to said road image, determining whether said horizontal line signal exists in said ROI-H and whether said horizontal line signal is interrupted by a barrier, calculating a distance between said image capture unit and the barrier in ROI-G (Region Of Interest-Ground), and outputting a barrier warning instruction responsive to detection thereby of horizon interruption by the barrier within an image region defined by said ROI-H and ROI-G; and at least one warning device receiving said barrier warning instruction from said processing device and emitting at least one barrier warning alert.
