Method and apparatus for generating infrastructure-based basic safety message data
First Claim
1. A roadside infrastructure system for generating basic safety message (BMS) data, the system including a roadside module comprising:
- a camera configured to provide an image of a predetermined fixed area;
video analytics coupled to the camera and configured to process the image to detect objects within the image, the video analytics being further configured to output a position of a detected object;
a BSM generator coupled to the video analytics and configured to receive the position of the detected object and to generate a BSM comprising the position of the object and an indicator identifying the BSM as having been generated by the roadside module; and
an antenna coupled to the BSM generator and configured to receive the BSM from the BSM generator and to broadcast the BSM.

Abstract
A roadside infrastructure system configured to generate and broadcast basic safety message data to augment vehicle safety applications. In one example, a roadside module of the system includes a camera, video analytics to process images from the camera to detect vehicles, a BSM generator that generates a BSM for each detected vehicle, and an antenna for broadcasting the BSM. In another example, the roadside module is configured to detect BSM data generated by equipped vehicles, to determine whether any detected vehicles are equipped vehicles generating their own BSM data, and to generate a BSM only for unequipped detected vehicles.

9. A method of generating basic safety message (BSM) data from stand-off sensors, the method comprising:
-
obtaining an image of a predetermined fixed area; processing the image to detect an object within the image; determining a position of the detected object; receiving vehicle-generated BSM data; determining whether the vehicle-generated BSM data originates from the detected object; generating a BSM comprising the position of the detected object only if the vehicle-generated BSM data does not originate from the detected object; and broadcasting the BSM. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A roadside infrastructure system for generating basic safety message (BMS) data, the system including a roadside module comprising:
-
a camera configured to provide an image of a predetermined fixed area; video analytics coupled to the camera and configured to process the image to detect objects within the image, the video analytics being further configured to output a position of a detected object; a BSM generator coupled to the video analytics and configured to receive the position of the detected object and to generate a BSM comprising the position of the object; an antenna coupled to the BSM generator and configured to receive the BSM from the BSM generator, to receive BSM data from BSM-generating objects, and to broadcast the BSM; and a processor coupled to the antenna and to the BSM generator, the processor configured to determine whether the detected object corresponds to a BSM-generating object and to control the BSM generator to generate the BSM only for non-BSM-generating detected objects.
