BICYCLE DIFFERENTIATION USING VIDEO DATA ANALYTICS

摘要

A vehicular observation and detection apparatus and system incorporates a detection framework using video analysis to differentiate between motorized vehicles and bicycles for improved traffic flow and safety at intersections. The detection framework creates virtual zones overlaid on lanes of a roadway and analyzes input data representing objects in the virtual zones collected from one or more cameras positioned at or near the roadway.

主权项

1. A method of detecting a presence of bicycles in a roadway for traffic signal controller management, comprising:
creating a virtual bicycle zone in a field of view that includes in one or more lanes of a roadway near a traffic intersection; generating a bicycle detection strip in or adjacent to the virtual bicycle zone; detecting motion inside the bicycle detection strip using an object detection means; and initiating one or more data processing functions embodied in a plurality of instructions configured to classify a type of object present as the object travels through the bicycle detection strip, the one or more data processing functions including determining whether the object present in the bicycle detection strip is classified as either a bicycle or as a motorized vehicle by analyzing a plurality of pixels that experience changes from frame to frame in a video data stream as the object passes through.
