System and method for monitoring vehicle traffic and controlling traffic signals
First Claim
1. A system for monitoring objects and controlling a flow of the objects through a flow point, the system comprising:
- at least one three-dimensional (3D) vector imaging sensor operable for capturing object data relating to an object;
a Sensor Processing Unit (SPU) associated with the at least one three-dimensional (3D) vector imaging sensor, the SPU being operable for processing the object data relating to the object captured by the at least one three-dimensional (3D) vector imaging sensor to represent the object as a node-based object in the form of a vector image comprised of one or more nodes based on a mathematical expression as opposed to a bitmap image or a raster image, the SPU being further operable for determining a tracked object from a plurality of the node-based objects based on a movement of the node-based object over time and for extracting motion vector data of the tracked object over time to represent the tracked object as a node-based object with motion vector data, wherein the motion vector data is an accumulation of motion data relating to the node-based object represented as a graphically numerical value in the form of a vector; and
a Central Tracking Unit (CTU) associated with the SPU, the CTU being operable for classifying the tracked object and for generating object tracking data from the tracked object, the CTU being further operable for predicting a future object state of the tracked object and for generating an object control output for controlling a control signal to thereby facilitate the flow of the tracked object through the flow point.

Abstract
A system and method for monitoring objects, such as vehicle traffic, and controlling a flow of the objects, such as vehicle traffic, through a flow point, such as an intersection having traffic control signals. At least one three-dimensional (3D) vector imaging sensor is operable for detecting an object and capturing node-based object with motion vector data relating to the object. A Sensor Processing Unit (SPU) is associated with the vector imaging sensor(s) and operable for processing the mode-based object with motion vector data, determining a tracked object from a plurality of the objects detected by the vector imaging sensor(s) and extracting the object data of the tracked object to an object database. A Central Tracking Unit (CTU) is associated with the SPU and operable for classifying the tracked object, generating object tracking data from the tracked object, predicting a future object state of the tracked object, and generating an object control output for controlling a control signal to thereby facilitate the flow of the objects through the flow point.
