Patent Images
1. A system, comprising:
- memory; and
logic configured to receive and store in the memory radar data and video data indicative of possible pedestrians and vehicles in an area under observation,the logic further configured to segment and classify the radar and video data and correlate classified radar objects with classified video objects to identify correlated objects of interest, wherein the logic configured to correlate classified radar objects with classified video objects comprises logic configured to search classified video objects for correlating classified radar objects, record in a matrix a likeness of the modalities for a property, compute a likeness score for each correlated object, and assign a confidence value for each object based upon the likeness score,the logic further configured to track the correlated objects to identify tracked pedestrians and vehicles,the logic further configured to receive and store in the memory traffic rules data indicative of pedestrian right of way traffic laws for the area under observation,the logic further configured to process the tracked pedestrians and vehicles with the traffic rules data to generate and store in the memory data indicative of alleged vehicle pedestrian right of way violations.

Abstract
A system and method for monitoring vehicle traffic and collecting data indicative of pedestrian right of way violations by vehicles is provided. The system comprises memory and logic for monitoring traffic intersections and recording evidence indicating that vehicles have violated pedestrian right of way. Two sensor modalities collecting video data and radar data of the intersection under observation are employed in one embodiment of the system. The violation evidence can be accessed remotely by a traffic official for issuing of traffic citations.

5. A method of recording evidence of suspected pedestrian right of way violations by vehicles, the method, comprising:
-
receiving raw video data from one or more video cameras collecting video data of an intersection of interest; processing the raw video data to form packetized video data; spatially segmenting the packetized video data and classifying video objects of interest; receiving raw radar data from one or more radar sensors collecting radar data of the intersection of interest; spatially segmenting the raw radar data and classifying radar objects of interest; correlating the radar and video objects of interest, wherein the correlating step comprises searching classified video objects for correlating classified radar objects, recording in a matrix a likeness of the modalities for a property, computing a likeness score for each correlated object, and assigning a confidence value for each object based upon the likeness score; tracking the correlated objects of interest; receiving traffic rules data indicative of pedestrian right of way traffic laws; applying the traffic rules data to the correlated objects of interest and recording alleged violation data. - View Dependent Claims (6, 7, 8, 10)

9. A method of recording evidence of suspected pedestrian right of way violations by vehicles, the method, comprising:
-
receiving raw video data from one or more video cameras collecting video data of an intersection of interest; processing the raw video data to form packetized video data; spatially segmenting the packetized video data and classifying video objects of interest; receiving raw radar data from one or more radar sensors collecting radar data of the intersection of interest; spatially segmenting the raw radar data and classifying radar objects of interest; correlating the radar and video objects of interest, tracking the correlated objects of interest, wherein the tracking step comprises predicting state vectors for prior known objects, updating state vectors based upon current observed objects, adding state vectors for new objects, and trimming state vectors for stale objects; receiving traffic rules data indicative of pedestrian right of way traffic laws; applying the traffic rules data to the correlated objects of interest and recording alleged violation data.
