Dynamic zone stabilization and motion compensation in a traffic management apparatus and system

摘要

A traffic management apparatus and system performs data processing functions on images in a video data stream to analyze differences between portions of the images and account for movement of a camera at a traffic intersection or other such environment. The traffic management apparatus and system is configured to be placed on a span wire or other non-fixed position at or near the traffic intersection.

主权项

1. A method of performing detection in a traffic environment, comprising:
receiving one or more initial images generated from a camera positioned at angle relative to and proximate to a traffic environment; performing a plurality of data processing functions configured to stabilize a detection zone for identifying a presence of one or more vehicles in the traffic environment, the plurality of data functions including
drawing one or more registration zones bordered by at least one fixed, known object in a first image frame of the one or more initial images representing an intended area of the traffic environment to be registered, the one or more registration zones drawn by establishing a presence of one or more vertical indicia and one or more horizontal indicia representing the at least one fixed, known object from the first image frame of the one or more initial images to create a template, the first image frame representative of a portion of an image in the one or more initial images,correlating additional registration zones drawn in image frames from subsequent images from the camera with the template, each image frame representative of a portion of an image in the subsequent images,continuously compiling a score from a comparison of the additional registration zones with the template,computing a change in at least one direction of the at least one fixed, known object across the image frames from the score; and applying the change in at least one direction to a plurality of vehicular detection zones.
